Gregory Melahn updated CMIS-735:
--------------------------------

    Proposal: 
Add a new service called appendContentStream 

2.2.4.17 appendContentStream
        Description: Appends to the content stream for the specified Document object
        Notes: 
                * A Repository MAY automatically create new Document versions as part of this service method. 
                  Therefore, the objectId output NEED NOT be identical to the objectId input.
                * The existing content stream for the specified Document may or may not be empty prior to 
                  calling this service method.  If the existing content stream was empty, this service has the effect of 
                  setting the content stream with the value of the input contentStream..
2.2.4.17.1 Inputs
        Required: 
                * ID repositoryId: The identifier for the Repository.
                * ID objectId: The identifier for the Document object. 
                * <contentStream> contentStream: The Content Stream 
        Optional: 
                * String changeToken: See section 2.2.1.3 Change Tokens.
2.2.4.17.2 Outputs
        * ID objectId: The ID of the document.
        * String changeToken: See section 2.2.1.3 Change Tokens.
2.2.4.17.3 Exceptions Thrown & Conditions
        * See section 2.2.1.4.1 General Exceptions
        * storage: See section 2.2.1.4.2 Specific Exceptions.
        * streamNotSupported: The Repository MUST throw this exception if the contentStreamAllowed
          attribute of the Object-Type definition specified by the cmis:objectTypeId property value of 
          the given document is set to notallowed. 
        * updateConflict: See section 2.2.1.4.2 Specific Exceptions.
        * versioning: The repository MAY throw this exception if the object is a non-current Document Version.

Another alternative would be to add an optional input parameter to setContentStream to indicate this was an append.

  was:
Several ideas come to mind.
1.  Add a new service called appendContentStream (preferred approach)
2.  Add an optional appendFlag to setContentStream
