PREMIS OWL Ontology for version 2.2
As a standard for preservation metadata, PREMIS is based on a data model that defines the entities that are described (Objects, Events, Agents and Rights), the properties of those entities (semantic units), and relationships between them. The PREMIS OWL ontology provides an RDF encoding of the PREMIS data model that defines the entities that are described (Objects, Events, Agents and Rights), the properties of those entities (semantic units), and relationships between them.
The first version of the ontology was based on the PREMIS Data Dictionary for Preservation Metadata, version 2.2. This version reflected an encoding of the PREMIS XML schema in RDF which was fairly faithful to the semantic units in the version 2.2 of the PREMIS Data Dictionary, enhanced by value vocabularies available at http://id.loc.gov/preservationdescriptions/. It was released in June 2013. The following documents that version of the PREMIS ontology:
- PREMIS Ontology (for PREMIS version 2.2)
This OWL ontology identifies the classes and properties used to describe preservation metadata in RDF.
- PREMIS Ontology Diagrams (PPT, 2KB)
This Powerpoint presentation shows diagrams illustrating the modeling of PREMIS in RDF.

The PREMIS OWL Ontology Revision Working Group released a draft revised version of the ontology and is soliciting comments before finalizing it. Further information and documentation are available at: [link to new page for version 3].
