Open CMIS cm:category not consistent?

I try to update categories on folder using java CMIS api and I had a little surprise:

when I set the category I have to provide the alfcmis:nodeRef, but when I browse categories I retrieve cmis:objectId and so in order to update categories I have to change all the list .

Isn't there a simpler way to do it? (I mean retrieving the same kind of information I provide to create)


I use apache opencmis java client version 1.1.0 and I request information upon an Alfresco community Edition 5.2.0


public String getCategoryRefByOid(String catOid){
    ItemIterable<QueryResult> query = session.query(String.format("select * from cm:category where cmis:objectId = '%s'", catOid), false);
    if(query.getTotalNumItems()!=0) {
        QueryResult next = query.iterator().next();
        String propertyValueById = next.getPropertyValueById("alfcmis:nodeRef");
        return propertyValueById;
    return null;
public void addCategoryToFolder(Folder parent, String categObjectId){
List<String> catIds = parent.getPropertyValue("cm:categories");
if(catIds==null|| catIds.isEmpty())
    catIds = new ArrayList<>();
    //catIds contains cmis:objectId instead of alfcmis:nodeRef so transform
    List<String> newCatIds = -> getCategoryRefByOid(oid)).collect(Collectors.toList());
    HashMap<String,Object> updated = new HashMap<>();
    updated.put("cm:categories", newCatIds);
    parent.updateProperties(updated, true);
    System.out.println("categ added");
}else{ System.out.println("categ ok");}
