Recently a new version of the Content Management Interoperability Services has been approved by OASIS. The CMIS standard allows accessing content for an application from a content management repository or sharing content between repositories. CMIS 1.0 was published in 2010 and is supported by many repository vendors and applications. SAP was participating in the standardization committee from the beginning on and supports CMIS in multiple areas in the ABAP and Java platforms. The document service in SAP HANA Cloud implements this standard and the  application SAP Mobile Documents relies on it.

The new features coming with 1.1 in brief:

  • a new protocol (Browser Binding) based on JSON
  • Type mutability
  • secondary object types
  • a new CMIS base object type (cmis:item)
  • bulk updates
  • appending content
  • Retention and Hold support
  • and more…

The browser binding allows CMIS applications running in the browser (Javascript) and is more efficient than AtomPub or SOAP. Secondary object types give much more flexibility with metadata handling. cmis:item is a new lightweight object. The SAP HANA cloud document service already supports some of the new 1.1 features (most important is the browser binding) and more will come.

For more details see the specification and the Apache Chemistry project.
