EO Product Metadata and OpenSearch SWG
OGC10-157r3, the Earth Observation Metadata profile of Observations & Measurements is an OGC Implementation Standard, adopted in 2012. This OGC standard provides a concise model for documenting Earth Observation Product metadata. The model is designed as a profile of the OGC/ISO Observation and Measurements standard and provides a layered model for the description of Earth Observation products. A generic Earth Observation Product “eop” schema is provided from which specific schemas for optical, radar, atmospheric, and so forth product types are derived. A number of improvements and corrections have been identified and need to be dealt with.
OpenSearch is a specification and a collection of technologies that allow publishing of search results in a format suitable for syndication and aggregation that can then be aggregated by larger indexes. OpenSearch is a way for websites and search engines to publish search results in a standard and accessible format. An EO Extension to OpenSearch is proposed that allows discovery of EO Products complementary to the OpenSearch Geo Spatial and Temporal Extensions (OGC 10-032).
