PLCS RDL
Top level standardized PLCS Reference Data (common for all projects) is made up of several related Reference Data Libraries:
- a representation of a classifiable subset of the PLCS EXPRESS schema as an OWL (Ontology Web Language) ontology
- a subset of the Dublin Core meta-data elements and terms, with a few OASIS-specific extensions, for internal management of the Reference Data (e.g. creator and date modified)
- the Reference Data itself, which includes:
- Classes
- a Class hierarchy
- properties of the Classes
- instances or Individuals based on the Classes
- relationships between Classes
- relationships between Class hierarchies and relevant PLCS EXPRESS schema elements.
