Removing the Joomla Generator Tag

A common request from Joomla web masters is the ability to remove the generator meta tag from the source output of the site.  This is usually for security reasons to make it less obvious that the site is running Joomla.  The generator value is really easy to modify and remove with one line of PHP code.

Fire up your favourite editor and load the index.php file of the default template on your site.  Most templates should have a block of PHP at the top of the file starting with and closing with ?>.  Find this block and just before the closing PHP brace, insert the following lines of code:

// Remove the generator meta tag
$this->setGenerator(null);
?>

What we have done here is told the template (that's what $this is) to set the value of the meta generator tag (that's what setGenerator does) to nothing (that's what null means).  When you do this, refresh your web page and view the source of the output.  Scan down from the top of the file to find the meta generator tag.

  <meta name="generator" content="" />

You can see it's obviously still there but the value is empty, giving you no clues as to what CMS is running the web site.  Nothing is probably the safest value, but you could set it to anything you like if you really wanted to.

There are several other files that could be loaded by Joomla in the template.  You will also need to do this to the component.php (that supports the Joomla Print View) and if you have a custom Error or Offline page, you will need to add the line of code to error.php and offline.php respectively.  You can find out more about these additional template files in the Template section of the Art of Joomla Developer Reference.

This is just another example of how flexible the Joomla templating engine is and why it's a makes Joomla a great choice to power your web site ... anonymously.

Joomla's hidden feature - hiding Intro Text

Joomla Web sites typically use the "Intro Text" and the "Read more button" and just continue the story from the Frontpage Blog view, or a Newsflash module - but it doesn't have to be that way.  You can actually hide the Intro Text when displaying the full article.

To do this, edit the article in the Joomla Administrator.

Click on the "Parameters (Advanced)" pane to the right of the text of the article.

Find the parameter called "Intro Text" and change the select list to "Hide".  Your article might look something like the following screenshot (click it to enlarge):

Screenshot

(You will note that I've fixed up some of the typo's since I took this shot.)

Save the article.

Now have a look at the article as it appears in a blog view, or a module, and then look at the full article.

The effects can be dramatic, such as in this article, or they could be more subtle.  You could make small adjustments such as you might see at spacedaily.com (this is not a Joomla site, but it's a site that inspired many of the early features I built into Mambo, the project from which Joomla was born) where the introduction on the frontpage changes slightly and the image includes a caption in the full article.

I hope you enjoy this useful, yet overlooked, feature of Joomla - hiding Intro Text.

Joomla Caching Explained

Any dynamic content management system makes the web server work and Joomla is no exception. However, most Web sites have content that does not change frequently where caching techniques can be employed to reduce reinventing the wheel (or the content as it may be) each time a page is visited. This article looks at the three levels of caching available to a Joomla 1.5 web site.

The idea behind caching is that once you’ve gone to the trouble of running a component, a module, or even building a whole page, it makes sense to take a copy and reuse that if possible. By default, Joomla does not cache any content. This means that every time someone visits your page, all the computations that it took to build the page are done over and over again even it there is actually no change in what the visitor sees. To overcome this, Joomla provides three levels of caching:

  1. Page caching
  2. View caching
  3. Module caching

Page Caching

Page caching is where Joomla takes a copy of the whole page when it is first displayed. If that page is then visited again, it takes that copy it saved and just displays the output, bypassing much of the code and many of the database queries that were required to build it.

Page caching is supported by the System Cache Plugin that comes with Joomla. To enable this, log into the Joomla Administator and choose Extensions -> Plugin Manager from the menu. Change the type filter to "system" so that the plugin is easier to find (or just search for "cache" in the filter box).

Screenshot

Click the icon in the enabled column to activate the plugin.

If you edit the System Cache plugin you will see that it has two options:

Screenshot

Use browser caching

The help text for this is a bit cryptic:

"If yes, use mechanism for storing page cache in the browser”

What this actually means is if you enable this option, Joomla will send a "304 Not Modiifed" header to the browser if the page has previously been cached. This will tell your browser that the page has not changed since you last saw it and saves another request to the server to actually get the contents of the page (assuming the browser stored a local copy). This is really only needed if visitors would return to pages while browsing your site. In this case, when they go back to a page they have previously visited, it can make the site feel a little more responsive. If your site visitors generally do not visit any page more than once during their browsing session, this option is of no real advantage.

Cache Lifetime

This is the time, in minutes, to store a copy of the page before a full refresh is done. The choice of time depends on how frequently content is updated. If you have news coming out every few minutes, then you will want to keep this setting low, even as low as one minute. If you only update your content once a day, then several hours may be appropriate. When adjusting the cache time, you need to consider dynamic modules and the content they display. While you may only update your content once a day, or even once a week, you you have a comments system linked to a "Latest Comments" module, and those comments are made, on average, once every 10 minutes, then you may need to set your cache time as low as 3 to 5 minutes so those changes are reflected in a timely fashion.

Page Caching Performance Testing

The following results are from testing a Joomla 1.5.14 site on a local development laptop (Macbook Pro 2.1.6 GHz Core Duo with 2 Gb of ram, PHP 5.2.6, MySQL 5.0.41).  The results where complied by turning on the System Debug plugin (and a little hacking to make the results show under cache due to a bug in the plugin).

SEF Off, System Cache Plugin Off

Application afterLoad:       0.000 seconds, 0.24 MB
Application afterInitialise: 0.072 seconds, 3.72 MB
Application afterRoute: 0.114 seconds, 5.46 MB
Application afterDispatch: 0.165 seconds, 6.86 MB
Application afterRender: 0.667 seconds, 7.98 MB

SEF Off, System Cache Plugin On

Application afterLoad:       0.000 seconds, 0.24 MB
Application afterInitialise: 0.077 seconds, 3.79 MB
Application afterCache: 0.080 seconds, 3.97 MB

The improvement is significant where caching delivers the same content about eight (8) times faster and uses half the memory.  This effectively constitutes a no-load test (in other words, ideal conditions) so it demonstrates the best possible performance you can get from turning caching on.  You will generally not see the same magnitude on a production server and probably even less in a shared hosting environment but the effect should still be noticable (although, if your pages are module heavy, you might see a greater increase).

Things to Watch When Using Page Caching

There are a number of things that you should watch when using the page caching plugin.  These include:

  • It does not apply to the Administrator.
  • It only applies to guest visitors (not logged in).
  • It does not apply to posted forms (which is a good thing).
  • It replaces security token with the correct value if required (another good thing).
  • It adds a profiling mark called afterCache (but due to a bug, you will never see it).
  • It stores a copy of the whole page after it is rendered based on the URL, so it will work for any unique URL regardless of the component.
  • Articles hits will not increase when page caching is turned on (making any sorting options on hits ineffective).
  • Javascript based dynamic content, such as Google Analytics or Google Adsense, still work.
  • Page caching does not work if Debug Site in Global Configuration is set to Yes.

The cached pages are stored in the /cache/page/ folder.  If your have a very large site on shared hosting you may need to watch your disk quota.

Clearing the Page Cache

Sometimes you need to clear the page cache so that you can see recent changes you have made to the site.  To clear the page cache, select Tools -> Clean Cache from the Administator menu.  Check the box next to the Cache Group called "page" and then click Delete in the toolbar.

View and Module Caching

View and module caching is different to page caching because it only stores copies of parts of the page.  Joomla still analyses and renders the template but you receive a performance boost because parts of the page can be retrieved very quickly.

View and Module caching is controlled by the Cache Setting section under the System tab in Global Configuration.

Screenshot

This allows you to enable caching and set the cache time (in minutes) and the handler (usually just file unless you have some fancy software installed on your server).

View Caching

View caching is only supported in components that enable it within their MVC architecture.  The only component that enables it in the Joomla 1.5 stack is the Articles component but only for guests (visitors that are not logged in) and only if you are not looking at a Category Blog page (the reason why this view is singled out escapes me).  Several JXtended extensions also support view caching.

View caching captures a copy of the output of the component before it is handed off to the template for rendering.  This can be useful if the amount of work to generate a page is processor intensive (that is, it makes the web server work hard).

Like page caching, the view caching is linked to the URL.

Module Caching

All modules (should) have a Caching option, usually in the Advanced Parameters pane and (should) have a Cache Time option which is the time, in minutes, to keep the copy of the module output.  The Caching option allows you to either Use Global, in which case use the setting in Global Configuration, or No Caching.  This means that you have three combinations to work with on your site:

1. Global configuration Caching is Off, so no modules cache their output.
2. Global configuration Caching is On, so all modules using Use Global will be cached.
3. Global configuration Caching is On but modules can individually opt out of caching by selecting No Caching.

It is important to note that this caching setting is different from the caching that the System Cache plugin does.  Actually, they are completely unrelated except that the Cache Plugin takes precedence.  In other words, when the System Cache plugin is page caching, a copy of the whole page, including the modules, is stored.  When the page is pulled out of cache, there is no processing to check whether any modules were set the No Caching.

There are several modules where you should choose the No Caching option.

The menu module generally should not be cached unless it is set not to expand (in other words, it stays open all the time).  Depending on how they are set up, split menu modules should not be cached.  If you do cache an expanding or split menu, it is going to get stuck and confuse your visitor.

Rotating content modules, such as the banners module, should not be cached.  If they are cached, then they will stay on the same content until the cache expires.  One exception is advertising modules that use javascript to display the content (such as Google Adsense).  This is not affected by caching.

The Polls module should not be cached otheriwise you risk getting an "Invalid Token" message when someone votes.

Highly dynamic content modules should either use No Caching or set a very low value for the Cache Time (one or several minutes).

Module caching will work regardless of whether the visitor is a guest or logged in.

Notes for Module Developers

Module developers need to be aware that module caching is handled by the module renderer in the JDocumentRendererModule class.  If the cache parameter is not provided, the module will never be cached regardless of the setting in Global Configuration.  To allow a module to be cached, you must include the following parameter in the module's XML file:

        
            name="cache"
            type="list"
            default="1"
            label="Caching"
            description="Select whether to cache the content of this module">
           
                value="1">Use global
           
                value="0">No caching
       
Introducing the new permissions in Joomla 1.6

Joomla 1.6 already demonstrates the ability to add your own user groups and access levels.  Mark Dexter has done a very good tutorial on this at http://docs.joomla.org/ACL_Tutorial_for_Joomla_1.6 which shows some of the supporting user interface under development.  Thanks also go to Mark for developing the design of the inheritance diagrams that you will see in this article.

This article presents the theory behind how the completed permissions management system, a part of the Joomla access control system, will work in Joomla as it currently stands to for Version 1.6 Alpha 2.  Screenshots of the user interface that allow you to set permissions will follow in other articles when the design of the appropriate pages becomes more stable.  This article also includes material presented by Andrew Eddie during his keynote address to the Sydney Joomla Day in October 2009.

Four Levels of Permissions Management

There are four levels of permissions management in Joomla 1.6 and these are set against the user groups defined in the User Manager.  Permissions can be set:

  1. in Global Configuration,
  2. then in each component,
  3. then in each category, and
  4. then in each article.

Each level allows you to choose more granularity for which to set the permissions.  For example, permissions set in Global Configuration will apply to the site as a whole without any additional work.  At the other end of the scale, you can customise the permissions of each article if that level of detail suits your business processes.  Obviously there is a trade-off.  As you apply specific permissions at deeper layers, the administration increases because you are micro-managing permissions on more and more objects.

Actions and Permission Rules

There are eight base actions that you can perform in Joomla 1.6.  These are:

  1. Login Site
  2. Login Admin
  3. Manage
  4. Admin
  5. Create
  6. Delete
  7. Edit
  8. Edit state

A component developer can add more, but most things that you want to restrict a user to do (based on the user groups they reside in) can be mapped to those eight actions.  However, each level of the permissions management system unlocks different abilities for each of the actions (sounds a bit like a computer game, doesn't it)

The rules for the permissions on these actions are quite easy because there are only three possible values as follows:

  1. You can leave a permission unset (in the case of Global Configuration), or you can set it to inherit the permissions from the levels above.
  2. You can set a permission to allow an action to be performed.
  3. You can set a permission to deny an action from being performed.

With that in mind, there are four simple rules by which Joomla evaluates whether you can perform an action.

  1. By default, you can't do anything.  We call this an implicit or soft deny.
  2. You can allow an action, and we call this an explicit or hard allow.
  3. You can deny an action, and we call this an explicit or hard deny.
  4. An explicit or hard deny always wins regardless of whether a soft or hard allow is also available.

There is one exception to these rules concerning the Admin action which will be discussed later.

Permission Inheritance

Permissions are always inherited, in order, down the levels and also down the user group tree.  For this reason, the user groups have been rearranged slightly in Joomla 1.6.

Screenshot

The Public Frontend and Public Backend groups have been merged together to form a single, top-level group.  Both the frontend and backend user group trees hang off the Public group.

The Super Administrator group is now called Super Users (to reduce confusion with the Adminstrator group).

With those things in mind, it's best to look at this with some diagrams that explain each action individually.  In each diagram as a number of symbols that represent the state of the permission that has been set for the action relative to both the user group and the permission level.  The following table explains the meaning of each symbol:

Screenshot An unset permission (which really means deny).
Screenshot An explicit, or hard, allow.
Screenshot An explicit, or hard, deny.
Screenshot An inherited allow.
Screenshot An inherited deny.

 

The Login Site Action

The Login Site action simply allows you to login to the frontend of the web site.  It has no effect at the component, category or article level (symbols shown dashed).

Screenshot

The Registered user group is set to Allow and, as you can see, this inherits down the tree through to the Publisher group.  Likewise, the backend groups are also given Login Site through the Manager group (set to Allow) and this inherits down the backend groups tree to the Super User group.

The Login Admin Action

The Login Site action simply allows you to login to the backend of the web site.  It has no effect at the component, category or article level (symbols shown dashed).

Screenshot

The Manager user group is set to Allow and, as you can see, this inherits down the tree through to the Super User group.

The Admin Action

Admin is a very special action.  When set at the Global Configuration level, it allows users in that group to perform any action regardless of any other allow or deny permissions (this is the one exception to the rule).  The default installation of Joomla will assign this permission to the Super Users group.

At the Component level, the Admin permission allows a user to change the component options (these are accessed via the Toolbar button called Preferences or Parameters in Joomla 1.5) which also includes the ability to change the component permissions.

Screenshot

Because the component options allow you to change the component permissions, you need to be careful how this is assigned.  The diagram above shows that in Global Configuration we have not assigned Admin to any user groups.  This is because that would also make an Adminstrator into a super user (and then they would be able to do anything).  However, in each component we have set Allow for the Administrator Group.  This means that users in the Administrator group are able change component options, but users in the Manager group will not because we have left the action unset.  In fact, users in the Manager group will not even see the Toolbar button for the options.

One thing to note is that if you install a new component (represented by the "New" component in the diagram) the Administrator group will not automatically have the Admin action.  Providing the component supports options and permissions, you will need to go into the component options and manually add the Admin action to the Administrator group.  In summary, this means that only your Super Users are allowed to assign who else can have access to change permissions.

The Admin permission has no effect at the Category or Article level.

The Manager Action

At the Global Configuration level, the Manage action has no effect (but can still be set).

At the Component level, the Manage action allows the user group to actually access the repsective component.

Screenshot

The diagram above shows that at the Global Configuration level we have set Allow for the Administrator group.  Unlike the Admin action, setting the Manage action globally means that any user in the Administator group can access any component, even new ones that are installed by the site master.

At the component level we can see that the Administrator group inherits Allow for all components.  However, Manager group has allow set individually for each component.  You can see that users in the Manager group will not have access to extension installation or languages because the action has not been set (therefore the implicit deny rule applies).

The Manage action has no effect at the Category and Articles levels.

The Create Action

The Create action allows a user to create categories and content in categories in components.

Screenshot

The diagrams shows that only the Manager groups has set this action to Allow in Global Configuration and the Author group has been set to Allow at the component level (specifically, only in the Article Manager and Web Links Manager).  The Administator, Editor and Publisher groups also inherit the Allow setting at their respective levels.  This means that a users in the backend user groups are able to create content in any component and any category, and also create categories.  Users in the author, editor and publisher group are able to create articles in any category from the frontend.

The Create action obviously does not apply for articles (because if they exist, you've already created them).

The Delete Action

The Delete action allows a user to delete categories and content in categories in components.

Screenshot

The diagrams shows that only the Manager group has been set to Allow.  The Administrator group also inherit the Allow setting.  This means that only users in the Manager and Administrator groups can delete categories and content in any category in any component.

The Edit Action

The Edit action allows a user to modify categories and content in categories in components.

Screenshot

The diagrams shows that the Manager group has been set to Allow in Global Configuration.  The Editor group has also been set to Allow but only at the Component level (specifically in the Articles and Web Links components).

The Administrator group inherits the ability to edit categories and content from the Manager group at the Global Configuration level.

The Publisher group inherits the ability to edit categories and content from the Editor group at the Component level.

However, we have not set the Author group at the Component level.  This prevents a user in the Author group from editing any content or any categories (note that the ability for users in the Author group to edit their own content has not been implemented yet). 

The Edit State Action

The Edit State action allows a user to modify secondary information, such as the published state, of categories and content in categories in components.

Screenshot

The diagrams shows that only the Manager group has been set to Allow in Global Configuration.  The Publisher has also been set to Allow but only at the Component level (specifically in the Articles and Web Links components).

The Administrator group inherits the ability to edit categories and content from the Manager group at the Global Configuration level.

The Author and Editor group have not been set.  This prevents a user in the Author or Editor groups from changing the published state of categories and content in the respective component.

Conclusion

This article provides an introduction to interpretting the new permissions management system in Joomla 1.6.  The key points to remember are:

  1. Permissions inherit down the user group tree in order, and down the four levels in order.
  2. By default, a soft deny applies until you Allow an action but then an explicit, or hard, Deny completely prevents access to the action.

We'll look at the effects of adding users to multiple groups and placing permissions on specific categories in future articles.

Bridgeway Releases Legal Hold 2.1, Learns How Companies Work

When it comes to eDiscovery Bridgeway Software (site) goes straight to the source — their customers — to understand exactly the processes they use. So when it comes to Bridgeway Legal Hold 2.1, Bridgeway’s newest release, the new enhancements reflect the needs of their users.

Focusing on the business side of things is what Bridgeway does. Technology for technology sake doesn’t make much sense to Rich Hall, vice president of eDiscovery and Brian Johnson, director of marketing at Bridgeway. CMSWire spoke with them recently about Legal Hold 2.1 and about how they work to better understand how their customers work.

Learning from Lawyers

Upon developing 2.1, which provides customers the functionality to properly manage and control the legal hold process delivered in an easy to use and easy to deploy application, Bridgeway talked to lawyers to understand what they need to collect, review and process date quickly and efficiently.

What they learned wasn’t revolutionary, yet not always apparent:

  • If the process is complicated, customers won’t use it.
  • Technology isn’t important if it isn’t easy to use, easy to implement and more efficient.
  • There is more to business than eDiscovery.

Bridgeway consistently works with companies to develop more business-minded processes and ways to practically improve how matter management fits into the bigger picture. In order to do this Bridgeway asks companies about their existing processes. Not only can they learn how those within the enterprise are executing searches and organizing data, it provides both parties with a teachable moment.

Prepared Inside and Out

The legal hold process is best carried out when people are equipped to make informed decisions. Bridgeway’s unified approach to legal hold lets in-house legal departments stay in control of complying with “duty to preserve” obligations. Feeling prepared goes well beyond what software a company chooses, it lies within an organization to get everyone on board, absorb the process and circle back to evaluate.

Deployed as either a standalone application or part of Bridgeway’s integrated eDiscovery solution, Bridgeway Legal Hold is a complete solution for custodian and case management, notification, acknowledgment, interviews and collection management.

Customers can sample the benefits of streamlining the entire legal hold process, with Bridgeway’s 60-day risk-free trial of its Legal Hold solution. As well, Bridgeway will be showcasing its latest Legal Hold product at booth #500 at Legal Tech in New York, Feb. 1 – 3.

Consolidate Your Cloud Servers with Cloudkick

Are your skies a little too cloudy? Cloudkick is here to help. The application visually unifies the deployment of seven different providers, including EC2 and Rackspace.

Say No to Multiple Dashboards

Cloudkick's basic M.O. is to consolidate. With their all-in-one API, users get a view into the performance of several providers at once, and can hop from one to the next. Features include nifty management tools for monitoring cloud resources, like intuitive charts:

 Cloudkick performance data

 

And critical metric summaries (load, CPU, bandwidth, memory, and disk space):

Cloudkick monitoring overview

The benefits to this kind of thing are obvious. Cloud computing is – and continues to be – pretty big news. (Note: A recent Cloud Development Survey reported that 61% of the developers in Evans Data Corp believe that a portion of their IT resources will move to the public cloud within the next year.) Naturally, a middleman to control the lot could be a really constructive solution.

Additionally, the company claims that their tool is a great way to analyze the performance of the service providers themselves. For example, earlier this month Cloudkick provided visual evidence of an Amazon network issue (which has since been resolved).

Movin’ On Up

It used to be that Cloudkick primarily managed Amazon Web Services accounts. Now, the software offers a dashboard that enables customers to migrate to any supportcloud provider (EC2, Rackspace, Slicehost, Linode, GoGrid, VPS.NET, and Rimuhosting). And perhaps more importantly, it provides a type of freedom by relieving users from having to stick with a particular vendor’s approach. 

Said co-founder Bob Hrdinsky in an interview with CNET:

We feel that we're leading the democratization of the cloud - users have a lower barrier to entry in participating in the cloud, and don't have to fear the burden of relearning tool sets if they switch providers. We are offering people who use multiple providers (or simply manage multiple accounts from the same provider) a super-accessible way to do so.

Get it

During a time when cloud computing is as explosive as it is now, a tool like this is, at the very least, interesting. But could there really be a long-term market? Thankfully, it won't cost you a penny to find out. Cloudkick offers a 30-day free trial on all of their plans, and beyond that they accept payments on a month-to-month basis. Check it out.

Growing eDiscovery Market Sees Iron Mountain Division Expand

Growing eDiscovery Market Sees Iron Mountain Division Expand

Stratify, a California-based division of Iron Mountain (site) has acquired Legal Imaging Technologies to beef up its eDiscovery capabilities.

eDiscovery is a Booming Market

eDiscovery is a big topic among the likes of Gartner and Forrester, and one that all companies, big and small, should have a handle on. Single-point solutions are pretty rare, but are getting closer as the industry shakes down to a few larger players.

The latest move to make industry news is Stratify's acquisition of Legal Imaging Technologies (LIT) for an undisclosed amount. LIT is an expert in image processing and document conversion. The two companies have a partnership dating back to 2006, so this isn't news out of the blue. LIT is a major force in the San Francisco area where it has been involved in legal document support since 1993. 

Document Protection

The integration of LIT’s processes into Stratify’s eDiscovery capabilities will increase them by at least 200% in its data center operations supporting the North America, EMEA and Asia/Pacific markets.

Over the last couple of years, Iron Mountain has expanded and developed its solutions to rank as one of the major players in this increasingly important market. It also works on disaster recovery, archiving and document management, both in the cloud and on-premises.

Iron Mountain itself picked up Stratify for US$ 158m back in 2007 and shows little sign of slowing down as its business expands.

OmniUpdate Reports Strong 2009 with CMS for Higher Education

Crisis, what crisis? Almost every Web CMS vendor who has to or chooses to publicize their 2009 financials is reporting growth and bright future. Some are even going public. OmniUpdate (site) joins this joyous bunch and says 2009 was a success in its higher education focused web content management segment.

Last year was marked for OU as a year of record sales revenues. Other 2009 highlights include:

  • 28 new clients
  • Existing customers increasing/renewing their service levels/terms
  • 12 product releases with 16 additional capabilities and feature enhancements (e.g. multi-language preview, global find and replace, garbage can, Serena Collage conversion tool, Live Delivery Platform and others)
  • Onboarding of integration partners
  • Ability to deploy OmniUpdate's CMS — OU Campus — either traditionally or as SaaS

As with all privately-held companies, the amount of financial information being released is limited. For buyers looking to evaluate Web CMS products for higher ed verticals, record sales is probably a little too ambiguous to indicate the overall viability and stability of the company.

While growing revenue is good news, we’ll continue to watch OmniUpdate and update you on where these folks are headed.

Lucid Imagination Turns 1, Triples in Size

Lucid Imagination (site) has survived their first year of business with flying colors. That is, the enterprise search company reported that they more than tripled in size over the last 12 months.

Open Source Search = <3

We can’t say that Lucid’s impressive numbers surprise us. As a one-stop kind of shop for technology that has more than 9,000 downloads per day and over 4,000 organizations using the software (Netflix, Alfresco and Myspace included), we wouldn’t expect anything less.  

What it comes down to is that effective search functions have always been critical for productivity, but 2009 saw an especially big spike in interest in the Apache Lucene technology, including the CIA's investment.

As Lucid Imagination's CEO Eric Gries put it, there were two big trends: "the pent-up demand for delivering timely access to corporate information in all its forms, and the disruptive innovation of Lucene/Solr open source search."

In response to this demand, Lucid's recent updates include the LucidWorks Certified Distributions for Solr 1.3 and Solr 1.4, as well as for Lucene 2.4 and 2.9. 

Ready to hop on board? You'll be lodging with an impressive lineup, including AT&T, Nike, Sears, Ford, Verizon, The Guardian, Elsevier, The Motley Fool, Cisco, Macy’s and Zappos.

eDiscovery Appliance Can Process up to 1 Terabyte per Day

What’s faster than a speeding bullet, more powerful than a locomotive and capable of leaping tall buildings in a single bound? Superman, of course, but when it comes to processing data at the speed of 1 terabyte per day and scales to 100 million documents on a single appliance – that’s version 5.5 of Clearwell eDiscovery Platform.

CMSWire recently spoke with Kamal Shah, vice president of marketing; Venkat Rangan, co-founder & chief technology officer and Kurt Leafstrand, director, product management at Clearwell Systems ( site) about the release of 5.5 and its impact on eDiscovery.

Clearwell is confident that its platform’s end-to-end eDiscovery capabilities mark the beginning of a “new era in eDiscovery processing” and with it will transform the way analysis and review of large volumes of data is carried out.

The Demand for Scalability

Scalability, after all is in high demand. Recent surveys have shown that in 2009 the average case size increased by 24 percent, making it necessary to process large amounts of data in a short time period across a single appliance that can handle growing volumes of data.

Clearwell seeks to deliver. Not only does 5.5 scale up to 100 million documents on a single appliance, but it also offers a variety of new capabilities that make processing data for early case analysis simpler, easier and quicker to administer, including:

  • Pre-processing filters and analytics
  • Extract containers / embedded objects
  • Automatically OCR image content
  • Full Unicode support + language identification
  • Global de-duplication
  • Create discussion threads
  • Perform social network analysis
  • Immediate availability for analysis / review

Highways of Data

Rangan likens the increase in scalability to transforming a single road into a six-lane highway. Data can be pushed through faster, filling up all the lanes to maximize space.

Clearwell E-Discovery Platform version 5.5 will be generally available in the second quarter of 2010 and will be showcased at Legal Tech NYC
