The Connected Asset OMAS implements the open metadata ConnectedAssetProperties API for an OCF connector.  An OCF connector is a connector that supports the Open Connector Framework (OCF). It has two APIs:

  • An API to access the asset it connects to
  • An API to access the metadata about the asset the connector accesses

The ConnectedAssetProperties is the second API on an OCF connector - the one for the metadata about the asset.   It is a generic API for all types of open metadata assets. However, it assumes the asset's metadata model inherits from Asset (see model 0010 in Area 0).

 


The Connected Asset OMAS returns metadata about the asset at three levels of detail:

  • Asset Summary - used for displaying details of the asset in summary lists or hover text
    • Type - information about the specific type of the asset
    • QualifiedName - official name of the asset (name from Asset - model 0010 in Area 0)
    • ShortDescription - short description about the asset (assetSummary property from ConnectionsToAsset relationship - model 0105 in Area 2)
    • Description - full description of the asset (description from Asset - model 0010)
    • Owner - name of the person or organization that owns the asset (owner from Asset - model 0010)
    • Classifications - list of classifications assigned directly to the asset, or its schema/definitions
  • Asset Detail - adds the following information to Asset Summary.  It is used to display all of the information known about the asset with summaries of the relationships to other metadata
    • Properties - properties and nested structures for the asset (these are defined in the type model)
    • Relationships - summaries of the relationships to other assets
  • Asset Universe - adds the following information to Asset Detail.  It is used to define the broader context for the asset
    • Infrastructure - details of the underlying infrastructure supporting the asset (all from Area 0)
    • Collaboration - details to the people, products and feedback that are connected to the asset (see Area 1 of the model)
    • Definitions - details of the schema(s) and definitions associated with the asset (see Area 3 and Area 5 of the model)
    • Governance - the list of governance requirements, typically associated with the classifications associated with the asset (see Area 4 of the model).
    • Annotations - details of the annotation added by the discovery services (see Area 6 of the model)
    • Lineage - details of the lineage for the asset (see Area 7 of the model)
