Introduction

A number of folks have been interested in aligning CMIS and OpenSocial.  While there was an initial prototype of this done earlier this year, we need to take the next step and document the base set of use cases and high-level positioning.

...

Many enterprise social platforms have some basic form of file management, and increasingly, OpenSocial is becoming part of the programming model that these platforms offer for integration at the application (gadget) layer, as well as the server to server integration layer (REST). Increasingly, customers of both CMIS systems, and social platforms are expecting these two systems to "just work together". By aligning with CMIS, the OpenSocial community will get the benefit of a more complete, feature rich data model that can easily be plugged in at the server layer with a CMIS system. The CMIS community benefits by having a rich social model that can be used to foster collaboration around the content that resides in their systems. The open ecosystem of vendors, application developers, and customers benefits by having clearly defined boundaries among standards, a consistent Web 2.0 social application model, and perhaps most importantly, an open standards based integration path for enterprise systems.

Use Cases

Document & Folder CRUD Operations

Explain basic crud use case in more detail here.

...

CMIS supports the notion of document sub-types, which inherit certain properties and attributes from their parents.  Sub-types may require certain properties/attributes to be defined in order to create documents of that type.  We must, at minimum, allow gadget developers to retrieve the repository's sub-types and metadata to facilitate creation of those sub-types.

CMIS Queries

CMIS supports querying, such as full text searching within CMIS documents.  For the first pass, OpenSocial will not support querying operations (subject to change).

...

Deprecating Albums and Media Items

As a result of this effort, there will no longer be a need for the OpenSocial specification to carry forward the definition and APIs for Album and Media Item. As such, they will be deprecated when support for the new APIs & data model that is based on CMIS is introduced. Whenever possible, we'll outline the migration path from the old APIs to the new data model. In addition, there are social constructs that will be carried forward and remain the responsibility of the OpenSocial based container.
