[Geodata] CSW, OpenSearch-Geo, OAI-PMH

[Andrew Turner]

There is discussion started by Cameron Shorter on the Mass-Market-Geo
OGC list (an open list) about the differences between CSW and
OpenSearch-Geo.

In general, the problem with these large standards is the
unreadability of the standards documentation and lack of simple
examples. My suggestion was to have someone write up a 1-page HTML doc
presenting CSW with some examples - similar to the OpenSearch-Geo or
GeoJSON spec pages.

- http://www.opensearch.org/Specifications/OpenSearch/Extensions/Geo/1.0/Draft_1
- http://wiki.geojson.org/GeoJSON_draft_version_5

Perhaps Jeroen or Stefan Keller or someone that knows (and hopefully
has implemented) CSW or OAI-PMH can help by writing such a short,
useful page for each? :) These could then reference one another as
potential developers/users investigate the various protocols and want
to understand their uses/strengths/issues.


Thanks,
Andrew
