Unique objectId for different document versions?

The CMIS 1.0 spec says Note: When a document is versioned, each version of the document is a separate document object. Thus, for document objects, an object ID actually identifies a specific version of a document."so when I make a query "SELECT * FROM cmis:document" and then upload a new version of

Hi,

That's a known issue in Alfresco 3.x. If you are seeing this issue with Alfresco 4.x, you are probably using the wrong (old) CMIS URLs.
Check this page for the new URLs: http://<host>/alfresco/service/cmis/index.html

I was using the old CMIS Atom feed so thanks for pointing that out and I confirm I now see the unique Ids. This actually solves many of the difficulties I was dealing with in terms of accessing metadata from older versions of a document. Do you know if it's possible to extract the Paths for an older version? For example I am doing ((DocumentImpl)session.getObject(<OBJECTID>)).getPaths() which returns the path for the most recent version of an object but an empty array for older versions of an object.

Many thanks

Adam

Hi Adam,

From a CMIS perspective older document versions are not filed. They are not children of a folder. Therefore they don't have a path.
You have to go back to the latest version to get the path. For example:

((Document)session.getObject(<OBJECTID>)).getObjectOfLatestVersion(false).getPaths()‍
