# Connected Asset Open Metadata Access Service (OMAS)

The Connected Asset OMAS implements the ConnectedAssetProperties API that is
available on every **OCF connector**.

An OCF connector is a connector that supports the open connector framework (OCF).
It has 3 sets of APIs:
* An API to return properties about the connector and its connection
* An API to access the asset it connects to
* An API to access the metadata about the asset the connector is used to access

The Connected Asset OMAS is the third 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:

* getAssetSummary - returns the summary information organized in the assetSummary structure.
* getAssetDetail - returns detailed information about the asset organized in the assetDetail structure.
* getAssetUniverse - returns all of the common metadata properties connected to the asset such as its schma, meanings
and platform.

These structures are defined in the OCF module as POJO property objects.
