== Ontology ==

Ontologies provide a set of defined terms and relationships between the terms to capture the information that describes the physical, functional, performance, and programmatic aspects of the system.

Common ways for describing such ontologies is Entity, Relationship, and Attribute (ERA).LML uses the ERA approach, because ERA is often used to define database schemas. LML extends the schema with Attributes toon Relationships to reduce the number of relationships needed, just as attributes reduce the number of entities needed.

In alignment with the first goal of LML, Entity, Relationship, Attribute, and Attributes toon Relationships have equivalent English language elements: noun, verb, and adjective. <ref name="specification"/>
