I'm poking my way around the open source channels and lurking for information.  To be honest, I'm a professional Microsoft developer by trade.  I haven't made the switch, yet, to open source tools.  I do run Mandrake Linux at home on one machine to handle mapping multiple domains to a Windows 2000 Professional box.  (IIS on Win2KPro only allows one domain.)

Anyway, I came across Zope.  It claims to be an application server. 

Zope is a leading open source application server, specializing in content management, portals, and custom applications.

That can be a broad term, and I am only posting this for my own benefit (yours too, if you're as green as I am in open source).  I have dabbled in Java, PHP, and Perl, but nothing substantial.  So, forgive me if this sounds ignorant.

Anyway, the Christian Open Developers' Network encompasses a project called Centrallix, which also claims to be an "application server."  So, needless to say, I wondered what the difference was.  (I'll investigate this more myself later, of course.)  Here is Centrallix's own definition of what the system is:

Centrallix is a web-based app server and data management engine featuring data abstraction, structural embedding, "pro"-DHTML generation, a SQL engine for multi-source queries, and object-based development.

OK, there are the definitions.  I'll try to find more later on both.  If you have any insight into either, please comment on this entry (see the attached comment link).  Thanks.

I found this blurb about an open source weblogging software package by linking from connexions.  Anyway, it's new to me.

What is Greymatter?

Greymatter is the original opensource weblogging and journal software. With fully-integrated comments, searching, file uploading and image handling, completely customisable output through dozens of templates and variables, multiple author support, and many other features—while having perhaps the simplest installation process and easiest-to-use interface of any program offering this level of functionality—Greymatter permanently raised the bar for weblogging and journaling, and it remains the program of choice for tens of thousands of people around the world.
