CDMI 3.0 is the third major revision of the Cloud Data Management Interface, which provides a standard for discovery and declarative data management of any URI-accessible data resource, such as LUNs, files, objects, tables, streams, and graphs. Version 3 of the standard reorganizes the specification around data resource protocol "exports", data resource declarative "metadata", and adds new support for "rels", which describe graph relationships between data resources. This reorganization highlights common use cases for using CDMI to discover and manage multi-protocol access to stored data.

This presentation will provide an overview of the changes and additions to CDMI 3.0, and will cover how CDMI is used to solve the following common data management challenges:

1. As a data access client, how can I discover which protocols can be used to access a data resource?

2. As a data management client, how can I control which protocols can be used to access a data resource?

3. As a data management client, how can I specify desired storage management behaviours for a data resource?

4. As a data management client, how can I efficiently transfer and package data resources for portable transfer between systems?

The presentation will conclude with a discussion of the CDMI 3.0 release timeline and a call for participation for interested attendees to get involved in the standardization process.
