Hi Haibin,

Thank you for the link.

Also, I found the use cases of CDMI a related read for this group:

Thanks.

Dear all,

I would suggest to have more discussion about the remaining issue from the past IETF meeting. We may continue the discussion about meta data. If we can solve it here in the list, we can update the architecture draft (maybe the reqs draft as well) and start the WGLC for them.

Hi Haibin,


>From the Quebec city minutes

http://www.ietf.org/proceedings/81/minutes/decade.txt


I understood that the following issues were open for DECADE metadata:
1) Do we make metadata immutable?
2) What is contained in the metadata?


My feedback is as follows:
1) Yes, make metadata immutable
2) Define a minimum set of information for the metadata.  So far, Time
To Live (TTL) and Access Control List (ACL) were discussed and seem to
be two items that are logical to include in the metadata


I would be interested in hearing feedback from other members of the WG.


Akbar

Hi Akbar,

Speak as an individual, I agree with you on 1). For 2), we should make a minimum set of metadata at the beginning, but I think we should allow extensibility. 

I think that the hash should NOT be made over the metadata, but only over the object itself. Because the metadata may change.

BR,

Hi Akbar,

IMO, even the metadata is immutable, the content publisher may still change it with new metadata, for example, refresh the TTL. In this case, if the object itself is not changed, both the content publisher and content requester do not need a new hash string for the object, and the content publisher does not need to redistribute the new object identity to the content requester. Does that make sense?

BR,
-Haibin
