Standard API Protocol for ECM Systems?

Question

I am wondering if there is an established standard or protocol when working with APIs for document management systems or ECMs. For example, let's say I'm working on a new product and I want it to have support for both FileNet and Documentum. Is there a protocol established across the major ECM systems that I could target my application for? This may very well not exist, so I'm asking because I'm sure one of you will know.

Answer 1

Content Management Interoperability Services (CMIS) was an attempt at standardization:

Ovum urges organizations to take a "solutions view" to ECM by thinking about their pain-points and then shortlisting vendors that provide solutions that best address these issues. Consider mixing and matching solutions from different vendors to create a best-of-breed approach to ECM. However, this will require integration between different vendors' products, so ensure that the solutions selected adhere to CMIS (Content Management Interoperability Services), the standard for interoperability between content management systems
