Open Source Content Management systems

Off-late, I have been scouting in Open source community to find tools which can be useful in my organization. Yesterday, my colleague mentioned that his team is looking for an alternative to our enterprise CMS. That encouraged me to focus on CMS this time, just so as to make my efforts worthwhile. 

Here are my findings..

Open Source based CMS are achieving popularity because of the increased maturity of these products. This is evident from the fact that the commercial CMS solutions are feature rich but a typical small or medium size enterprise needs barely 20-30% of these features.

The market trend suggest high adoption rate in Europe & USA. APAC adoption trend shows improvement. Specific to the Industry domains, Media & Entertainment, Retail & Govt domains have very high rate of adoption. Manufacturing & BFS have moderate rate of adoption.

Here are some notable Open source CMS
- Alfresco
- OpenCMS
- Apache Lenya
- Hippo CMS

Here is a comparative study of these tools. Source CMS Matrix
