The Data Provision Subsystem provides data sharing, data discovery and data access functions and is composed of a data provision service object, a data inventory service and a data storage controller.

Computational Model for Data Provision Subsystem

The Data Provision Service is a proxy service for the Data Provision Subsystem. It supports the following interactions:

• share data (server). Public interface for allow data to be shared.

• discover data (server). Public interface for searching provided data.

  • access data (server). Public interface for accessing provided data.

The Data Storage Controller is a controller object that persists the published data. It supports the following interactions:

• post data (server). Interface for persisting data to the data storage controller.

• retrieve data (server). Interface for getting data from the storage controller.

The Data Inventory is a computational object that allows data to be discovered. It supports the following interactions:

• index data (server). Interface for registering/indexing data in the inventory .

• query inventory (server). Interface for querying the inventory for registered/indexed data.
