Description

Over at https://github.com/gadomski/heystac I've implemented rudimentary crawling:

  • Visit each child catalog and collection
  • For each collection, fetch one item either from its item links or from its items endpoint

This seems generalizable to an extension, since the output could be useful it if were structured (things like crawl:start_datetime and crawl:end_datetime, roundtrip request times, etc). We should implement in stac-extensions, write up a spec and a json-schema for it, and then maybe make it its own https://github.com/stac-extensions.

Research direction

Start by reviewing the rudimentary crawling implementation in gadomski/heystac, especially its handling of child catalogs, collections, item links, and items endpoints. Define the extension’s crawl metadata and document the behavior, then add the requested specification and JSON Schema in stac-extensions; done means the proposal is structured and reviewable.
