Using the lists webservice I retrieve the items from a list. In the XML returned I can see the attribute ows__IsCurrentVersion="1"
which I assume is the same as the file object model (i.e. a boolean to say if it is current or not).
However I do not see a way to identify what revision it is? What should that attribute be?
By 'revision' do you mean version? If so, you are probably looking for one of these attributes:
ows_owshiddenversion
is an Integer (ex: 8)ows__UIVersion
is an Integer (ex: 4096)ows__UIVersionString
is a String (ex: 8.0)*edit*
Here is some more information after testing it using a Document Library. You should also check the other comments by Hugo and Janis, as they have some good information.
ows_owshiddenversion ows__UIVersion ows__UIVersionString
1 512 1.0
2 513 1.1
3 514 1.2
4 1024 2.0
5 1025 2.1
Most likely, what you are looking for is ows_owshiddenversion
.
