Can anybody teach me how to study ontologies on the Web as related to XML
etc.? What is the relationship between ontologies and XML etc.?
Many Thanks!

XML itself is nothing but some way to present knowledge.
The so-called 'hot' XML is just hot on terms for now.
The real hot things are the methods/ways to extract useful info from XML.
Just go to W3C, there are more than plenty of materials about XML and
your questions about ontologies. But, I doubt it'd would be helpful
unless you're doing research project on it.

why dont we learn it together here instead of ...?
I'd like to understand it well too. In today's talk, somebody talked
about ontology, but i'm still not very clear.
I found a link here for ontology:
http://www-ksl.stanford.edu/kst/what-is-an-ontology.html
It defines ontology as "a specification of a conceptualization", but it
is still too abstract :(
as i understand, ontologies are some rules, or constraints for some models.
hey, middleman, or anybody else, any idea?

I saw this word a couple of times in my lab project proposals.
What we did is to develop XML schemas to specify or standardize concepts.

a good suggestion made by you.
I would like to understand ontologies as generally an authoritative expression
of conceptual
relationships between a group of terms (entities) in a defined
area, such as ontoloties for a medical area, a branch of science etc.
XML is a tool to express ontologies. A variety of operations can be
applied to ontologies, e.g., modification and join with
each other etc.
Any comments?
