First of all, it's my pleasure to recognize Alfresco's 5th birthday. In January 2005, a group of eleven of us started on a fantastic journey from a familiar world, Enterprise Content Management, into an unfamiliar one, Open Source. During this time, we have re-kindled our excitement for ECM, learned a lot about open source and become the largest private open source company. Not bad for a little company in suburban England.
One of the things that we have had to learn and be flexible on is the whole area of open source licenses. It's been nearly three years since we went to the GPL license with Alfresco Community. The GPL was and is the most widely used open source license and provided a fairness of use that meant that we could feel comfortable to grow the project, company and brand. Alfresco is now one of the strongest brands in both open source and ECM.
Now we have grown the Alfresco brand considerably since its beginning, we believe that we can now move the Alfresco repository to the LGPL license. This moves us back to the model that is similar to the JBoss license model (see JBoss's "Why We Use the LGPL"), which we experimented with in the very early days of Alfresco. Compared to 2005, we see more of an opportunity to be a platform beyond individual applications, particularly with the emergence of CMIS. What the LGPL license provides over GPL is the ability to link in the Alfresco repository without affecting proprietary software that links it. As stated in JBoss's document:
We do this in the spirit of making Alfresco available as a CMIS platform and a general ECM platform to build content applications without inhibiting your business opportunities. What we hope is that your applications will build demand for Alfresco services from Alfresco Software, particularly in larger enterprise environments.
What this means practically, is that we are changing the license of all the software in the alfresco.war file. This is not an overnight operation, since every single files header needs to change to reflect the new license. Thus the license officially will change with the Alfresco 3.3 Community release in March. If you wish to consider alfresco.war today as LGPL, you may do so.
If you are an enterprise customer, then this won't affect you. You still have a full commercial license from Alfresco and have the full freedom of those terms.

We use the LGPL for JBoss because it promotes software freedom without affecting the proprietary software that sits alongside and on top of JBoss.This reflects our feeling too. The LGPL code is share and share alike, but you can link it with any proprietary code without affecting the license of that code. We have considered more liberal licenses as well, but we currently have two main LGPL components - Hibernate for database access and JBPM for workflow - which prevent us from going to something like Apache or BSD licenses. However, this is something we may consider changing in the future.

John,
I know this isn't really the best place to do this, but I couldn't find an email contact for you on this site. Do you take material from outside contributors?
I work for IT Brand Pulse, an analyst firm that is currently expanding its practice to cover document management, unified communications and electronic document delivery. One of the things I'm interested in doing is having Frank Berry, our founder and senior analyst, start blogging on established sites like yours. Please let me know if you have any interest in adding an author to your site.
If are interested in adding Frank to your roster of contributing writers, or have questions about IT Brand Pulse and its services, please do not hesitate to call me at 714-273-1398 or email me.
Attached is an Industry Brief we published recently based on an interview with Mike Harding, GM of the JUNOS business unit at Juniper and Vikram Mehta, CEO of Blade Technologies. You can view the corresponding articles at:

Seeking Alpha:

Our articles are widely syndicated because we tag them with stock symbols, so the Network Computing articles are picked up by Google Finance and the Seeking Alpha articles are picked up by Yahoo Finance.
In addition, our articles are widely distributed because they're popular. The #1, #3 and #4 most popular blogs on Network Computing right now are by Frank Berry.
Regards,
Jeff
