             Summary: Allow simultaneous/atomic update of both document properties+content
without PWC requirement.
                 Key: CMIS-529
                 URL: https://issues.apache.org/jira/browse/CMIS-529
             Project: Chemistry
          Issue Type: Wish
          Components: opencmis-client
    Affects Versions: OpenCMIS 0.7.0
            Reporter: Chris Hubick
            Priority: Minor


There exists a method Document.checkIn(boolean major, Map<String, ?> properties, ContentStream
contentStream, String checkinComment); which is used to simultaneously update *both* the properties
and content for the private working copy. Very handy.

However, if one is not modifying a private working copy, then they must perform *two* separate
method calls: CmisObject.updateProperties(Map<String, ?> properties, boolean refresh);
and Document.setContentStream(ContentStream contentStream, boolean overwrite, boolean refresh);

If a CMS implementation performs automatic version incrementing upon modifications, this will
then result in *two* version increments, instead of only one when using a private working
copy.  That is less than ideal.

It would be nice if the CMIS protocol had an atomic operation for this, and if anyone from
the Chemistry project is in contact with the CMIS working group, it would make a nice feature
for CMIS 1.1 :)  (I can't file this enhancement request in the OASIS JIRA, as it isn't really
public)

With the hope that such a protocol feature might be added in the future, or even without such
support, it could still be a nice feature for the OpenCMIS client API to provide programmers
an easy way to combine those two method calls into one, perhaps by adding a method like:

ObjectId Document.update(Map<String, ?> properties, ContentStream contentStream, boolean
overwrite, boolean refresh);

Thanks.
