The CMIS specification outlines a standard for content management interoperability services, enabling applications to read and write data across various content repositories. It includes a domain model, services for operations, and a SQL-like query language, enhancing developer efficiency by reusing existing knowledge. The specification has received support from major ECM vendors and offers implementations that developers can integrate into diverse programming environments.
