Jeff Potts commented on CMIS-295:
---------------------------------

It looks like you are using Alfresco as the back-end. In Alfresco, the description property (cm:description) is part of an aspect called cm:titled. The CMIS spec lacks support for aspects, but apparently there is a way to get/set aspect props via policies. At this time, however, cmislib lacks policy support.

>             Project: Chemistry
>          Issue Type: Bug
>          Components: python-cmislib
>         Environment: using revision 1038521
>            Reporter: Bernhard Reutner-Fischer
>            Priority: Critical

> I want to createDocument and store a "Document description".
> And i want to retrieve that description.
> There is no way i can see to pass in the description.
> When i manually set a description for a document in the underlying CMS then i cannot access that description anywhere in the properties!
> The only spot where that description show up in the retrieved document is in it's XML-representation, as "<summary>" field, which is really, really inconvenient :)
> So, both storing as well as retrieving the document description would be great to have!
> TIA && cheers,
> Gory details:
> The creation looks something like this, for reference:
>         upload_form = DocumentUploadForm(request.POST, request.FILES)
>         if request.POST.get(u'add_document') and upload_form.is_valid():
>             # we now have a django.core.files.uploadedfile.InMemoryUploadedFile
>             # Note: major takes a string, not a bool! # FIXME!
>             checkin_props = {u'major' : u'major_change' in request.POST and 'true' or 'false',
>                              u'properties' : {u'cmis:description' : request.POST.get(u'document_description')}
>                             }
>             ret = create(request, path, request.FILES['document'], auto_revision=True, checkin_props)
> def create(request, foldername, filename, auto_revision=False, checkin_props={}):
