Metadata Store System. The Metadata Store system includes services for the storage of metadata objects in XML format. The core service is the MDStore Sevice, a web service that implements the factory pattern for the management of MDStore units. An MDStore unit is a metadata store capable of storing metadata objects of a given metadata data model. Consumers can create and delete units, and add, remove, update, fetch, get statistics on metadata objects from-to a given unit via the MDStore Service. The Service is implemented as an abstraction over the document-oriented storage MongoDB in order to exploit its high-scalability and replica management features, but also to take advantage of out-of-the-box support with the Hadoop Map-Reduce framework, if necessary.
