Re: [search-ws] sru:recordPacking = unpacked ?

["Hammond, Tony" <t.hammond@nature.com>]

Hi Ralph:

I just realized that this is all much simpler than I had first proposed.

Proposal: To allow "unpacked" as a legal value for sru:recordPacking.

(Impact is that search response data would be removed from sru:recordData
although packaging wrappers could - and should? - be retained as these would
provide useful information such as schema URIs and namespace URIs.)
 
Currently we have a sru:recordPacking parameter which takes values "xml" and
"string". (This could be expanded  later to include other non-XML types,
e.g. "json".)

All I think would be required would be allowing for one additional value for
this parameter of "unpacked" which would substitute "xml" (or "string") if
the record data were not in place but had been preprocessed and removed
(i.e. "unpacked").

What I am proposing to implement in my service is to return unpacked records
for OpenSearch style responses (e.g. RSS, ATOM, JSON). I am hoping to have
this implemented next week so that I can show what this would look like on a
live implementation.

For now I have copied below what an RSS item would like as I propose to
return (see A). For comparison I also show (see B) what a "conventional"
packed type would like as an RSS item (and here the recordPacking is "xml").

If the SRU protocol allowed for "unpacked" as a legal value of
"sru:recordPacking" I would then be able to select either response form A or
form B according to user pereference.

I think this is now a very modest proposal. It also has the merit of being
logical and is backwards compatible.

Cheers,

Tony
