Content Management Interoperability Services (CMIS) is an open standard that allows different content management systems to inter-operate over the Internet. Specifically, CMIS defines an abstraction layer for controlling diverse document management systems and repositories using web .
CMIS defines a domain model plus bindings that can be used by applications to manipulate content stored in a repository.
CMIS provides a common data model covering typed files and folders with generic properties that can be set or read. There is a set of services for adding and retrieving documents ('objects'). There may be an access control system, a checkout and version control facility, and the ability to define generic relations. Three protocol bindings are defined, one using WSDL and , another using AtomPub, and a last browser-friendly one using JSON. The model is based on common architectures of document management systems.
The CMIS specification provides an API that is programming language-agnostic, as REST and SOAP are implemented in many languages.
Many of the original contributors to the specification believed a simplified and standardized way to access unstructured content across all vendors would increase the adoption of ECM products. But only if the standard could remain compatible with existing deployed systems. Much the way that ODBC Open Database Connectivity did for the relational database market in the 1990s.
The initial work of developing the momentum and use cases that led to the CMIS proposal was conducted by the iECM Initiative sponsored by AIIM. This ongoing project to foster interoperability among ECM systems is supported by the collaborative efforts of governmental, commercial, vendor, and consulting organizations.
