Last uploaded: May 1, 2026






Details
Acronym SIO
Visibility Public
Description The semanticscience integrated ontology (SIO) provides a simple, integrated upper level ontology (types, relations) for consistent knowledge representation across physical, processual and informational entities. It provides vocabulary for the Bio2RDF (http://bio2rdf.org) and SADI (http://sadiframework.org) projects., integrated ontology (types, relations) for objects, processes and their attributes. This project provides foundational support for the Bio2RDF (http://bio2rdf.org) and SADI (http://sadiframework.org) projects. website: http://semanticscience.org email: [email protected] mailing list: http://groups.google.com/group/sio-ontology
