CWIC Open Search

CWIC: CEOS WGISS Integrated Catalog

Why OpenSearch?
-Lightweight and simple
-Standards-based
-RESTful
-Low entry cost
-etc.

Working example:
CWICSmart + IDN Opensearch + CWIC Opensearch = :)

Discussion of CWIC Best Practices
-Conform to Open Search and OGC Specs
-Take ideas from ESIP Best Practices
-Add their own recommendations

Search steps
-User finds datasets of interest (e.g. MODIS)
-User finds granules of interest (spatial & temporal filters)
-User previews granules
-User downloads granules

CwicSmart
-A programmatic OpenSearch Client
https://api.echo.nasa.gov/cwic-smart

CwicSmart
-Dataset search: specify search terms, bounding box, start & end time in form fields
-Granule search: bounding box, start & end times
-Can search using other APIs
