[Tdwg-tag] RDF instead of xml schema

RDF to me appears on a level of abstraction making it very hard for me to
follow the documentation and discussion. Most of the examples are embedded in
an artificial intelligence / reasoning use cases that I have no experience
I am a biologist and I feel comfortable with UML, ER-modeling, xml-schema-
modeling, and - surprise - relational databases. I believe many others are as
well - how many datastores are actually build upon RDBMS technology?
To me xml-schema maps nicely to both UML-like OO-modeling and Relational DBMS.
I can guess about the advantages of opening this all up and seeing the world as
a huge set of unstructured statement tupels. But it also scares me.
Angst is a bad advisor. But then if only a minority of the current few people
involved can follow on the RDF abstraction level. A few questions I have:
* Would we be first in line to try rdf for such complex models as biodiversity
* Do Genbank/EMBL with their hundreds of employees and programmers use rdf?
Internally/externally? The molecular bioinformatics is probably 1000 times
larger than our biodiversity informatics.
* Why are GML, SVG etc. based on xml schema and not RDFS? Is this just
* Are there any tools around that let me import RDF into a relational database
(simple tools for xml-schema-based import/export are almost standard part of
databases now, or you can use comfortable graphical tools like Altova
-- I am just trying to test some tools to help me to visualize RDFS productions
(like Roger has send around) on a level comparable with the UML-like xml-schema
editors (Spy, Stylus, Oracle, etc.) I will try Altova SemanticWorks and Protege
over the next week. The screenshot seem to be about AI and semantic web much
more than about information models (those creatures where you try to simplify
the world to make it manageable...).
