Synthetic Biology:Semantic web ontology/RDF
From OpenWetWare
Resource Definition Framework - used for making statements about facts
<http://www.example.org/index.html> has a creator whose value is John Smith
the RDF terms for the various parts of the statement are:
- the subject is the URL <http://www.example.org/index.html>
- the predicate is the word "creator"
- the object is the phrase "John Smith"
Beware of thinking of RDF as a format for serailizing objects. The semantic web is different - it is weblike.
- Any document can (potentially) say anything about anything. There is no set of "slots" or "attributes" for a class. The properties defined in a schema are not the only properties which one can use to describe something which is in that class.
- An object can be in many classes. When you create a semantic web document about something, others can deduce more things about it, in vocabularies you have never heard of.
- Entity-Relationship and UML diagrams are useful for describing RDF -- so long as you remember the above.

Levels (from Semantic Web roadmap)
- Basic model contains just the concept of an assertion, and the concept of quotation - making assertions about assertions.
