Short for Open Document Management API, an open industry standard that enables desktop applications to interface with a document management system (DMS). ODMA simplifies cross-platform and cross-application file communication by standardizing access to document management through an API. ODMA allows multiple applications to access the same DMS without the need for a hard-coded link between the application and the DMS.

ODMA starts from the premise that desktop applications are file-oriented rather than object-oriented and must be managed in a way that is similar to how data is stored in a database. The users need a way to access files that are made from multiple applications (e.g., a MS Word document that contains an Excel spreadsheet and a graphic image within the file) no matter what platform or environment they are working with. Client-side compound-document architectures, such as PDF, HTML and the Windows OLE standard, need to manage the data on the server side. Complex data objects must be linked, embedded, cross-referenced, searched, queried, distributed, and made secure, -- as well as viewed, edited, and printed, just as objects in a DBMS.
