Temporal search #145

Open yemoski opened 1 year ago

yemoski commented 1 year ago

Solr can do this for DataOne searches

schema.org attributes: temporalCoverage, temporalCoverage discontinuous repeats, temporal (text), OWL time

[ ] Need two or more time periods to compare but don't mind which time periods they are (what does this mean?)
[ ] Seasonal search (e.g. "winter" observations or "walrus season" observations. This may require much finer granularity of temporal data than is often provided in metadata records, which may just have an overall range (e.g. 2004-2010)

At the moment, open-ended searches work great, but for the specific dates, you have to specify a year, month and day. It'd be nice to be able to just give a year, or a year and a month.

My current time range solution for repos we index ourselves breaks when someone puts a URL into the temporalCoverage field. This is allowed but none of the repos we index have done that... as far as I can tell, YET.

I'm starting with the first two on this list.

The interesting design problem here is how you let people pick ranges with concrete dates, but also just years, or deep time eras.

The search should not return results for datasets that have incomplete temporal coverage specified (e.g. a start date but no end date)
