Simple OML Diagram
Reminder: Because MS-Word 2000 is being used to generate these web pages, it is highly recommended that you use Microsoft Internet Explorer version 5.0 when viewing this site. The elements of the Classification Projection Diagram are illustrated in the following simplified diagram. An elaboration of this classification projection diagram, as depicted below, illustrates the core concepts in the OML model. This model renders more explicitly the connections found in the OML Grammar. As a rule of thumb, XML elements become entity types in the OML model, and attributes and content nonterminals (child embeddings) of XML elements become functions and binary relations in the OML model. A type is depicted by a rectangle and an entity is depicted by a large dot. The elements that are colored black are elements of Simple OML. They largely correspond to the RDF/Schema model. Although they are specified in the Simple OML Ontology, the generic classification and subtype hierarchies have not been included as types (rectangles), since their instances are not needed until CKML is specified. When more than one subrectangle (subtype) is present, the subtypes partition the supertype.
