Linked.Archi EA-as-a-Service Metamodel Definition

Extension ontology for modeling the EA function as an internal management consultancy. Provides vocabulary for EA service catalogs, service engagements, stakeholder satisfaction, EA capability portfolios, and maturity assessment. Addresses the Gartner 2025 prediction that by 2028, half of EA teams will rebrand themselves to emphasize their strategic role as business partners. Formalizes the shift from "architecture practice" to "architecture services" by making service offerings, engagements, outcomes, and satisfaction into queryable elements in the knowledge graph. Designed to be lightweight and adaptable — organizations customize the service catalog and maturity model to their operating model.

SHACL shapes for validating EA-as-a-Service models. Enforces governance rules: every service must declare required capabilities, every engagement must have an assigned architect and status, and every EA service must have a label.

Classification of EA service concepts by service type, engagement duration, stakeholder type, and maturity level.
