Announcing the Content Management Interoperability Services (CMIS) Specification
Today represents the start of a new era in Enterprise Content Management (ECM) interoperability as Microsoft, EMC and IBM announced a jointly developed specification that leverages SOAP, REST and Atom to enable communication with and between ECM systems. The new specification known as Content Management Interoperability Services (CMIS) defines a platform and language independent means of accessing ECM repositories and will be submitted to OASIS for advancement through its rigorous standards development process.

As well as enabling communication between ECM systems, CMIS will also enable rich, content centric applications and mashups to be developed independent of the underlying storage repository. For more details, you can download a draft of the specification or take a look at Ethan's post on the ECM team blog.
