Discovery Telecon 2011-12-13 OGC

OSGeo background

Started off in similar fashion to ESIP federated search. Have centers with lots of collections at different levels. Also federating non-space research communities (seadatanet?). Looking to reuse, used OpenSearch, linked up with OGC to document it. Looking to join our efforts.

Pretty much at the same level; initiatives with OpenLayers widgets and mass-market tools.

Principle: don't break mass-market tool. If Atom field resolves, needs to still work in Google Maps, Bing maps, etc. True, "enclosure", "icon" isn't really what we mean, but on the other hand, it does work in mass-market tools.

Try not to use community namespaces. Maybe get new values accepted by IANA.

Site has information only about OpenSearch engines, with links to OpenSearch Description Documents. Then query to discover their granules. Then look for metadata and/or enclosure.

Will send working examples.

Sentinel launching over next few years. Have reqt that mass-market interface is an OpenSearch with Geo and Time extensions.

Have critical mass of data available...

Also, cf. CWIC, will put OpenSearch interface on top of CWIC.
