# Open Connector Framework (OCF)
The OCF, as the name suggests, is an open framework for supporting connectors.
Connectors support access to remote assets such as data sets, APIs and software components.
OCF Connectors also provide access to metadata about the asset and they may call the Governance Action Framework
GAF to execute appropriate governance actions related to the use of these assets in real-time.
## Terminology
There are a number of key components within the OCF:
* **Connector** - this is a Java object for accessing an asset and its
related metadata and governance functions.
* **Connection** - this is a Java object containing the properties needed to
create a connector instance.
Connection properties are typically managed as metadata entities in the metadata
repository but they can also be manually populated.
Connections have 2 sub-objects:
* **ConnectorType** - this is a Java object that describes the type of
the connector, including the Java implementation class of its connector provider (see below).
* **Endpoint** - this is the Java object that describes the server endpoint where the asset is accessed from.
* **Connector Broker** - this is a generic factory for all OCF connectors.
* **Connector Provider** - this is a factory for a specific type of connector.
It is used by the Connector Broker.
* **Connected Asset** - this is the asset that the connector is accessing. It is hosted on a server
and the connector makes the remote calls necessary to retrieve, update, delete the asset itself.
The connector also includes an API to retrieve the metadata properties about the connected asset.
## Open Metadata Type Models
Model 0040 defines the structure of an Endpoint and
model 0201 defines the structures for Connections and Connector Types.
Model 0205 defines the linkage between the connection and the connected asset.
## Java Implementation
The OCF provides the interface schema and base class implementation for these components.
The Java implementation is located in packages org.apache.atlas.ocf.*:
* **org.apache.atlas.ocf** - Java interface and base classes for Connector and Connector Provider
plus the implementation of the Connector Broker.
* **org.apache.atlas.ocf.ffdc** - Implementation of the OCF's error codes and exceptions.
* **org.apache.atlas.ocf.properties** - Implementation of the properties for connections and connected assets.
These are simple POJO objects.
## Related Modules
The ConnectedAsset OMAS (omas-connectedasset) supports the retrieval
of connection and connected asset properties from the open metadata
repository/repositories.
The AssetConsumer OMAS (omas-assetconsumer) embeds the OCF to provide
client-side support for connectors.
The Open Metadata Repository Services (omrs) provides implementations
of OCF connectors for accessing open metadata repository servers.
These connectors are collectively called the OMRS Connectors.

* </p>
* <p>
* Each connector implementation is paired with a connector provider. The connector provider is the factory for

* It is supplied to the connector later during its initialization through the initializeConnectedAssetProperties() method.

# Open Connector Framework (OCF) FFDC
Package org.apache.atlas.ocf.ffdc provides the first failure data capture
(FFDC) support for the OCF module. This includes an error code enum,
a runtime exception, a base class for checked exceptions plus
implementation of each specific checked exception.
The error code enum (OCFErrorCode) has an entry for each unique situation
where an exception is returned. Each entry defines:
* A unique id for the error
* An HTTP error code for rest calls
* A unique message Id
* Message text with place holders for specific values
* A description of the cause of the error and system action as a result.
* A description of how to correct the error (if known)
Each exception (whether a checked or runtime exception) has two constructors.
* The first constructor is used when a new error has been detected.
* The second constructor is used when another exception has been caught.
This caught exception is passed on the constructor so it is effectively
embedded in the OCF exception.
Both constructors take the values from the OCFErrorCode
enum to define the cause and resolution. These values are passed
as individual parameters so that subclasses implemented outside of
the OCF packages can define their own FFDC values.
