Organizations benefit from advocating the use of OCF connectors for their systems because the OCF connectors provide a consistent approach to governance enforcement and audit logging. The virtual data connector is an example of this type of connector. This type of connector delegates the requests it receives to to one or more physical data resources. An OCF connector can represent a simplified logical (virtual) data resource that is designed for the needs of a specific application or tool. OCF connectors are not limited to representing data resources as they are physically implemented.This is particularly useful for data science tools where the metadata can help guide the end user in the use of the data resource. This provides applications and tools with a simple mechanism to make use of metadata as they process a data resource. The first set provides access to the data resource and the second set provides access to the metadata that the open metadata repository has about the data resource. The OCF connector provides two sets of APIs.If the location of the data changes, then the named connection configuration is changed in the open metadata repository and the application will be connected to the new location the next time they request a connector.There is no need to hard code user ids and passwords in the application code - nor manage keystores for this sensitive information since the open metadata and governance server handles this.The application need only supply the name of the connection and provided they have the appropriate security credentials then a connector is returned to them for use. Network and security parameters for accessing the data resources are managed in the open metadata repository as part of a named connection.The application supplies the name of the connection it needs and assuming it is authorized, the OCF returns the connector.Īpplications and tools benefit from using OCF connectors because: The OCF acts as a secure factory for connectors to data stores. These details are normally hard-coded in the calling application code which creates both a maintenance and security issue. These data resources may be data stores (databases, files etcetera) or APIs to application data, transformations and analytical functions.Īccessing data through an APIs requires knowledge of the network address of the API for the data store, plus additional parameters such as userId and password. It provides interfaces and factories for named connectors (called OCF Connectors) that access distributed data resources. The Open Connector Framework (OCF) governs access to data assets and metadata through standard mechanisms whilst preserving (where possible) the native asset access APIs.
