We have several resources available to help support the usage of the
ontology.
The Ontology FAQ can be useful for a
new user to get a better understanding of ontology related
terminology as well as decisions and rationale for the ontology.
The Ontology Cookbook
collects frequently used ontological expressions that can be useful
for writing queries, for using the pub/sub facility.
The OAA Query API gives the APIs
that need to be used for accessing the information using the CALO
ontology.
To make the updates into the ontology, you can use OAA Update API.
To use the ontology in pub/sub, the necessary API is forthcoming (as of 2007-01-16).
