The Ontologies section provides help with developing new ontologies and also with finding and reusing existing ontologies.
Schemapedia is a good place to find an existing ontology.
Linked Datasets provides links to the growing number of Linked Data datasets that can be incorporated as part of developing a Linked Data application.
The Data Hub's list of LOD Linked Datasets is a good place to find Linked Data datasets.
