Content Management System (CMS) investigation [2005-08-19]
One of the key success factors for any type of collaborative team (not just software development) is the ability to quickly and effectively capture and disseminate their knowledge. In terms of ubiquitity, you just can't go past a web server and web browser. However, all but the most trivial web sites really need some sort of Content Management System. Without some sort of tools based assistance, it just gets too hard to achieve ...
- Ease of content creation and instant publishing (absolutely crucial)
- Ease of locating, indexing or searching for information (also absolutely crucial)
- Content and presentation consistency
- Version control
- Access control
- Interoperability with other systems
Starting from a base of Internet standards, there are many different approaches to capturing and dissemination information. From the most ephemeral, such as instant messaging, through to email lists, static web pages, forums, blogs, wiki-wikis and so on.
However, when it comes to a balance of easy content authoring, instant publishing, collaborative approach, capturing non-linear thought processes and incremental assembly into more structured documentation. Then, systems based around a wiki-based approach are hard to beat. Perhaps the premier example in the world is the Wikipedia, a collaborative encyclopedia. Wikis are not without their problems, but they are a reasonable compromise.
This technical note is written from the perspective of knowledge capture and dissemination, as well as integration with other systems, rather than pure content publishing.
Underlying technology choices
If it is possible to get an out-of-the-box solution that will meet 100% of your current and future needs, then what's under the covers of your CMS probably isn't an issue.
However, typically, a CMS will need to be customized. Perhaps only the skin for external appearances. Also, you may need to integrate the CMS with other information systems in the organization. Finally, there may be a need to extend the CMS with new functionality via site specific programming. In these cases, the technology underpinning the CMS becomes a factor. A key consideration will be whether either in-house skills and / or external assistance is available to make the modifications.
Since my current weapon of choice is Java, my starting point was to check out Java based CMS projects / products.
However, in the open-source world, it would appear that many people favor PHP based CMS systems. This article is one example ... Ask TSS: Do any Java CMS/Portals match the PHP ones?
There is a tension between the quick and (often) dirty PHP based systems that are feature rich and constantly changing and improving, but are (often) a complete mess internally ... and, on the other hand, the slower and well-engineered (perhaps over-engineered) Java based systems. One thing is for sure, the PHP community seems to have got it's CMS act together a couple of years ahead of the Java crowd.
Is Daisy the best CMS ? For your needs, perhaps not.
But, what I like about Daisy is ...
- Content is based on standard HTML tags. No obscure CMSor Wiki specific mark-up to learn
- Based on Cocoon 2 (an old favorite of mine) and Java
- Is well engineered with clean seperation between content, logic and presentation / layout (thanks to Cocoon)
- Handles non-HTML content and other documents quite readily
- Reasonably easy installation and administration
- Is actively under development
- Has a number of neat features, e.g. document collections and faceted browsing
Other noteworthy open-source CMS
WikiMatrix is an
excellent web-site that reviews and provides detailed comparison between a
bewildering array of CMS offerings !
CMSMatrix is another source of (self-proclaimed independent) information and analyst.

Over time, the JSR 170: Content Repository for Java technology API specification will become more of a factor.
There also appears to be some interest in these systems being built using the JSR 168: Portlet Specification.
