Description

Assume a CMIS client wants retrieve a high-fidelity PDF rendition of a large, volatile Word document with minimal idle time. In this case, a standardized mechanism may be needed to inform the client that the rendition is 'not yet ready'. This scenario might occur, for example, when the client is interfacing with a Linux-based CMIS server that forwards Word-to-PDF conversion requests to a remote Windows server. Here, the rendition generation may take some time to complete.

Would it make sense to send a standard '202 - Accepted' response code to the client to indicate this 'rendition is not-yet-ready' condition? Once the rendition becomes available, the rendition retrieval would return a standard 200 success response. Do you have other ideas about how this use case might be supported in a standard way across CMIS servers?
