Custom Metamodel & Shapes

Every enterprise has its own terminology: internal cost center codes, regulatory classifications, SLAs, or custom technology types. Kyb provides a dedicated Metamodel Studio at /ontology where organization administrators can define custom classes, attributes, relationships, and SHACL shapes.

Tenant-Isolated Named Graphs

Your custom metamodel definitions are strictly tenant-isolated. They are stored in your organization's dedicated named graph in Oxigraph (e.g. urn:kyb:org-ontology:{orgId}) using the custom namespace (https://kyb.fyi/ontology/custom/). Your custom types are immediately available to all members of your organization and remain completely private.

1. Custom Classes

Create custom entity types that specialize or extend core ArchiMate layers:

• Parent Class Inheritance: Inherit from core ArchiMate classes (e.g., creating a SaaS Product subclassing Application Component).
• Layer Classification: Assign the element to an architectural layer (Motivation, Strategy, Business, Application, Technology) for automated swimlane layout.
• Custom Icons & Labels: Choose visual symbols and display labels for the canvas and element palette.

2. Custom Properties & Datatypes

Attach typed metadata fields to any entity or relationship. Kyb supports:

3. SHACL Constraint Shapes

Every property can be paired with automated SHACL constraint shapes:

• Required Fields (sh:minCount 1): Mark properties as mandatory for specific entity classes.
• Allowed Values (sh:in): Enforce that only approved enum values are accepted.
• Datatype Bounds: Validate minimum/maximum values on integers and decimal currencies.

Guided Concept Migration

When an administrator removes or renames an allowed option from a controlled vocabulary, existing entities might become invalid. Kyb prevents silent corruption through automatedImpact Checking:

Before the change is committed, the Concept Migration Modal displays every entity currently using the deprecated option, prompting the administrator to map the legacy values to a new replacement option or clear the property safely.
