[jira] [Commented] (CMIS-883) Asynchronous Rendition Retrieval

["Florent Guillaume (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CMIS-883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14326010#comment-14326010 ] 

Florent Guillaume commented on CMIS-883:
----------------------------------------

Another option to communicate this information to the client would be to abuse slightly the content type and return for instance a {{Content-Type: application/pdf; incomplete=true}}. Parsers should be able to work with that.

> 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?
