Hi adam, sorry I don't check this list that often, for specific Zemantic 
questions you should use the z3-zemantic at codespeak.net mailing list, 
reachable from http://zemantic.org

I don't know, I think you might be using an older version of Zemantic that 
confused the term "catalog" because at the time I wrote it there was no Zope 
3 catalog and my brain was catalog centric.  There might be some 
unfortunately uses of the term catalog still in the docs.  Paul has been 
yelling at me to update those ;)

But now there *is* a Zope 3 catalog, and I have resolved my own confusions, so 
it is important to make sure you don't use the term or verb "catalog" the 
wrong way when you are referring to Zemantic.  The correct term (and verb) is 
"graph".  Zemantic objects are graphs, when you modify a graph, you are 
graphing.

Next, the currently released versions of Zemantic work only on the Zope X3.0 
release, *not* the Zope 3 trunk.  I am working on a trunk version now, but my 
priority right now is to help Dan get an rdflib 2.1 out the door, so it might 
be a couple of weeks before I can land a 3.1 version of Zemantic, but I will 
be landing one soon.

Last, the 3.1 version of Zemantic will work hand in hand with Zope 3 catalogs.  
That might also be the source of your confusion if you read that somewhere 
like on the zemantic list.  How that happens is a discussion for the zemantic 
list. See 

http://codespeak.net/pipermail/z3-zemantic/2005-March/000025.html

Zemantic is changing fast, actually a more accurate way to put it is that 
Zemantic is disapearing fast, Dan and I have been pushing many features from 
Zemantic down into rdflib, so that the 3.1 version of Zemantic will just be 
interfaces, skins and ZCML that "wrap" rdflib.  All the components will come 
from rdflib.

So I would advise waiting a bit (for 3.1), or diverting your energies into 
helping devlop 3.1 with us, or steping back to Zope X3.0 and using a released 
version of Zemantic (the most recent is, I belive, 0.6).
