Ontology Workshop Relation of the MGED Ontology to MAGE Brief review of the MGED Ontology Policies for coding the MGED Ontology in MAGE Examples Discussion

OntologyEntry in MAGE BioMaterial Package

OntologyEntry in MAGE Description Package

MGED Ontology v1.1.6 “Finished” version of the MGED Ontology Available at Two major branches: Core and Extended Consists of classes, properties, and individuals (instances) Classes may have instances or be abstract Classes may refer to other ontologies, controlled vocabularies

“Finished” MGED Ontology A stable version of the MGED Ontology that can code can be based on. The next major version will be developed in concert with MAGE v2. A few minor changes to be finished up this month Additions allowed (like MAGE, as long as it won’t break code).

Available at html Daml file Rdfs file NCI DTS Browser

MGED Ontology is registered as GO Xref and at MOBY abbreviation: MO database: The MGED Ontology object: ontology term example: MO:Action generic_url: url_syntax: url_example:

MO has two major branches: Core and Extended daml file in OILed

MO consists of classes, properties, and individuals (instances)

Classes may have instances or be abstract

Classes may refer to other ontologies, controlled vocabularies

Policies for coding MO in MAGE All MO terms are to be database referenced When the MAGE category in the OntologyEntry tag is a MO class with individuals. When the MAGE category in the OntologyEntry tag is a MO class without individuals because it is an abstract class. When the MAGE category in OntologyEntry tag is a MO property. The MO OntologyEntry class and its subclasses.
