    1413Hi Darius, 
    1514 
    16 I am continuing to look through this, still not finished. So far I have 
    17 one main question: 
    18 I see that there are things like "hasClass" "hasClass1" "hasClass2"; 
    19 Shouldn't there be just one "hasClass" with just one R number?

    2420Hi Rahul,

    26 No, template roles with the same name are unique on their own, so if two 
    27 unrelated templates both have a role called hasClass then those two 
    28 roles will have different R number IDs. However specialized templates 
    29 have the same role IDs as their parents. This will let us easily 
    30 associate a template and other templates specialized from it, because 
    31 they will share the same role IDs, but they will not share role IDs with 
    32 any other templates.

    42 Can you please explain the assumption behind above statement bit more. 
    43 Is the assumption coming from part 7 or part 8? because I dont think 
    44 this is intended in part 7 and might cause issues while moving to JORD.

    5038Hi Rahul,

    52 I haven't seen anything about role IDs in Part 7 or 8. The Part 8 sample 
    53 OWL files use the role name as the ID. Certainly Parts 7 and 8 have 
    54 nothing about ids-adi (R number) IDs.

    56 I remember some discussions with Julian about whether role IDs should be 
    57 unique or only unique in the context of a template, and the decision was 
    58 that they should be unique by themselves. I think this makes sense, and 
    59 it gives several advantages, such as the ability to change role metadata 
    60 without affecting other templates, and the ability for specialized and 
    61 non-specialized templates to interoperate as mentioned before. Do you 
    62 see any problems or disadvantages with this approach?

    75 But unfortunately it is little off topic and if anything current implementation is contradicting it.

    89 1. Thought part 8 examples don't use R numbers they use same id similar to "#hasClass" when referring to this role in all the templates. (Verified for examples above).  Since IDs are dumb, the only important fact remains that it is same in all the templates.  
    90 [[BR]] 
    91 2. Going back to Julian's statement above even a single id for hasClass is unique by itself. It is not dependent upon any specific template.  
    92 [[BR]] 
    93 3. All the templates which have role name "hasClass" are trying to convey same meaning at that "thing filling that role is at the class level as compared to thing filling the other role(s)" so each "hasClass" role need not have separate id. If the meaning changes then there should be a separate role all together and then off course separate id e.g. #hasRole1.
