The document discusses the integration of domain-specific languages (DSLs) and ontologies through metamodel integration, focusing on the Business Entity Domain Specific Language (BEDSL), Feature Oriented Domain Analysis (FODA), and OWL2 ontology language. It outlines a proposed solution for creating an integrated metamodel that supports constructing a domain model that includes device structure, feature definitions, and constraints. The result is a cohesive framework that allows for modeling various business entities and their relationships within network management.
