Alfresco CMIS query return objectId that contains semi-colon and version

Question

I'm using alfresco 4.2 with OpenCMIS java client library CMIS 1.1.

    String serviceUrl = "http://URL/alfresco/api/-default-/public/cmis/versions/1.1/atom"; // Uncomment for Web Services binding

    // default factory implementation
    SessionFactory factory = SessionFactoryImpl.newInstance();
    Map<String, String> parameter = new HashMap<String, String>();
    // user credentials
    parameter.put(SessionParameter.USER, "admin");
    parameter.put(SessionParameter.PASSWORD, "admin");
    // connection settings
    parameter.put(SessionParameter.ATOMPUB_URL, serviceUrl); // Uncomment for Atom Pub binding
    parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value()); // Uncomment for Atom Pub binding

    // Set the alfresco object factory
    // Used when using the CMIS extension for Alfresco for working with aspects
    List<Repository> repositories = factory.getRepositories(parameter);
    Session session = repositories.get(0).createSession();

    // Get some repository info
    System.out.println("Repository Name: "+session.getRepositoryInfo().getName());
    System.out.println("Repository ID: "+session.getRepositoryInfo().getId());
    System.out.println("CMIS Version: "+session.getRepositoryInfo().getCmisVersion());

    List<String> cmisObjectId = new ArrayList<String>();

    StringBuilder sb = new StringBuilder();
    sb.append("select * from ged:document m");

    // execute query
    ItemIterable<QueryResult> results = session.query(sb.toString(), false);

    for (QueryResult qResult : results) {

        PropertyData<?> propData = qResult.getPropertyById("cmis:objectId");
        String objectId = (String) propData.getFirstValue();
        cmisObjectId.add(objectId);
        System.out.println(objectId);
    }

The result is :

e8137d5d-cf50-41c4-844a-ec98a44ee73a;1.0
f86557af-89c3-4287-85c4-381e47896c1a;1.0
d56b4e1e-e1dc-4514-9bd2-24080b7879a8;1.0
59a0a9a8-8309-43b6-8040-bb3e9e448171;1.0

But I would like the id of the node without the version number, to use it for REST API Call.

Thanks.

The CMIS Object ID is defined as being an opaque string. The format will differ between repository implementations, and may differ between versions of a repository.

If you want the Alfresco NodeRef, and you're sure you're talking to an Alfresco server, then the property you'll want is alfcmis:nodeRef

If you connect to your repository with the Apache Chemistry CMIS Workbench, you can see the properties it reports, and from there see things like this
