# Base ontology

The base ontology is the seed for defining application-specific ontologies. It defines the basic types and property/class definitions themselves, so that classes and properties may be created.

Subpages:

XML schema (XSD) – Basic types definitions (int, double,...)

Dublin Core metadata (DC) – Common superproperties for documents

Resource Description Framework (RDF) – Core RDF classes to keep the internal consistency of the ontology

RDF Schema (RDFS) – Data-modelling vocabulary for RDF data

Nepomuk Resource Language (NRL) – Properties describing the ontologies.
