Data Governance - Knowledge Catalog

Hi,

we are investigating what the best way is to map an UML class diagram to the Knowledge Catalog.

This for the class, attributes, data types, enums, assocations,...

did anybody do this before?

any recommendations?

thank you,

René

Map UML Elements to IKC Components

• Classes → Data Assets:
  • Each UML class becomes a data asset.
  • Use the class name as the data asset name.
  • Add a description from the UML documentation.
• Attributes → Metadata Properties:
  • Define attributes as metadata fields for each data asset.
  • Specify types (e.g., string, integer, date) as seen in the UML diagram.
• Relationships → Lineage or Associations:
  • Represent relationships between classes as data lineage or associations in IKC.
  • Use links to establish dependencies or flows between assets

Prepare a Mapping Document

• Create a structured mapping table, for example:

  UML Class Name	IKC Asset Name	Attribute	Type	Relationship/Dependency
  Customer	Customer Data	Name	String	Linked to Orders
  Order	Order Data	Date	Date	Linked to Customer

Automate the Mapping (Optional)

• Use tools like Python scripts or the IBM Knowledge Catalog APIs to programmatically create assets, assign metadata, and set up relationships.
• Parse the UML diagram (e.g., in XMI format) and convert it into API calls to IKC.

Enrich Metadata

• Add business terms, classifications, and governance rules to enhance each asset's metadata.
• Use existing business glossaries in IKC to link terms to assets.

Validate the Mapping

• Review the mapped structure in IKC to ensure consistency and correctness.
• Test the usability of the catalog by searching for assets, browsing relationships, and validating metadata accuracy.

Publish and Share

• Once verified, publish the catalog and share it with stakeholders.
• Assign roles and permissions for managing and accessing the catalog.
