Reverse-Geocoding in Time at SFO Museum

Have you ever wanted to be able to reverse-geocode a point not just in space but also in time? Have you ever wanted to do that date-filtering with fuzzy or imprecise dates, encoded using the Extended DateTime Format (EDTF) ? Have you ever wanted to do both of these things with an arbitrary subset of location records? Have you ever wanted to be able expose these things as a web application and an API that doesn’t need to talk to a remote database? Have you ever wanted to be able to deploy those applications both locally and as serverless applications running on a cloud-provider’s infrastructure? Now you can.

Tools for Complex and Ambiguous Dates at SFO Museum

The EDTF specification does all the work of defining the rules and semantics for encoding complex and ambiguous dates in to well-defined and structured strings and the go-edtf packages do the work of decomposing those strings in to values and flags that can be manipulated by computers.
