Draft OpenSearch SRU Extension for Review

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

Hi All:

Just sharing ahead of tomorrow's call a draft for an OpenSearch SRU
Extension:

    http://nurture.nature.com/opensearch/sru/

This is aligned with latest (Oct. 19) SRU 2.0 draft and includes all request
parameters.

An SRU Extension would be a key step in OpenSearch/SRU alignment, not least
because we now have SRU implementations which are OpenSearch addressable.

The draft is reasonably complete (in terms of parameters) but might need
some additional text up front.

Some issues:

    1. License. This draft (following other examples) states that:

    "This document is made available subject to the terms of the Creative
Commons Attribution-ShareAlike 2.5 License."

    Are we OK with that, or do we want another license?


    2. Namespace. I just followed current OpenSearch usage and put a
namespace as

     http://a9.com/-/opensearch/extensions/sru/2.0/

    I guess we would want to set our own namespace. I also think it might be
useful to version as SRU version (i.e. "2.0").

    (For the nature.com OpenSearch service we are currently using a local
namespace:

    http://www.nature.com/opensearch/ns/opensearch/extensions/sru/

    but would like to upgrade to a more standard form.)


    3. Format. For demo purposes I'm using the OpenSearch doc template. I
would hope that we can go ahead with this format and register the document
to appear in the standard OpenSearch extension directory:

    http://www.opensearch.org/Specifications/OpenSearch/Extensions


    4. Parameters. I have marked the following parameters as deprecated
since they are synonyms for OpenSearch parameters:

    * sru:query [ = "searchTerms" ]

    * sru:startRecords [ = "startIndex" ]

    * sru:maximumRecords [ = "count" ]

    (I think the last two are effective synonyms - need to double check.)
 

Hopefully we can discuss further tomorrow.

Cheers,

Tony
