ESDSWG 2022 Federated STAC

STAC is a great candidate for a federated search solution. It also has a lot of traction in our community beyond the use case of federated search.

Our current best practice for federated discovery is OpenSearch as developed by the ESIP community and executed by CEOS WGISS (including NASA EOSDIS Common Metadata Repository - CMR).

However, OpenSearch utilization and development is somewhat static.

STAC can be used, with some additions, for federated search with the same architecture. Given STAC’s traction in the earth data science community, we believe it will be a viable solution for federated discovery for the long term. This presentation was presented at the 2022 NASA ESDSWG Meeting (April 19-21, 2022).
