The Java marketing machine has worked assiduously to associate the concept of a portal with the Java language, but there is no real dependency between the function of a portal and its implementation language. See the section for CakePHP CMS.

Some interesting questions and comments about portals.

It is a browser plugin, which introduces browser dependencies, but the project is Open Source and seems to be active and well-supported.

From the site:

Mozilla RDF was originally used to support the Aurora/Sidebar user interface and SmartBrowsing metadata services. It's main use in Mozilla now is as a common data model and API for use in XUL-based applications.

From the project page:

Node linking and Metadata

The Relationship Manager module is intended to allow free-form links between nodes, recording not just that one page relates to another, but HOW it relates. ... The core module is made available to be extended by other modules that wish to make use of the generalized relationship management functions. Several examples of simple modules that leverage this power are provided as optional plugins.

The major plugins are:

Revised: Sept 20 2007

After a great burst of initial activity with the NINA project and then with Dan Morrison driving the Relationship Manager project, there was good momentum to semantic web projects for Drupal. But the efforts seem to have gone into something like a hiatus during the the last year or so.

Note: my understanding of these services is evolving and may be incorrect at this point. Updates coming soon probably ...

Of course, the best example of a Seaside-powered site may be the Seaside site itself. But there are several interesting ( and either cheap or free ) hosting sites for Seaside web applications.

A strong candidate for a Smalltalk RDF/OWL inference engine is the Smalltalk Open Unification Language (SOUL).

Found it !

Modularization will help tame the Squeak image a bit and may be critical to the long term success of Squeak. The image is getting very big, especially the Object class which is a bad place to be big.

Drupal has been good to me, no question about it.

I had planned to roll up my sleeves and do some PHP coding to make it work the way I wanted. But, between the Drupal core, Links and a few other modules, it pretty much does what I need already ( with maybe some more meta-data for the links ). So instead of coding PHP, I devote my time to creating content, which was the point of the exercise in the first place. It's worked very well for my purposes.

According to the Drupal web site,

Seaside

To get a good feel for Seaside development environment, read the excellent technical introduction by Shaffer Consulting.

Note that the article was written in 2005 and may be obsolete in parts. For example, Seaside now supports several object-oriented databases, including Gemstone.

I finally got XAMPP working correctly on multisession CD. No, not symlinks, although it looked like it for a while.

Copy down from the Puppy Linux Discussion Forum:

So far, I've got Squeak installed on Puppy 210 and 2.16 disk installations. No go for CD / multi-session CD, no surprises there. Need to stick symlinks in appropriate places and try again. I hope it's a unionsfs issue and not a VM issue.

Update: July 20, 2007

The Puppy Linux Multi-Session CD is one of the great hacks of all time. In a nutshell, you boot into the Puppy operating system from a CD or DVD disk, do some work and then save the work back to the CD by using a standard multi-session write. The next time you boot from the CD, your work from the previous session is restored into your live-CD file system.

It may not sound like much but no other major Linux distribution can do it.
