I just wanted to say this is being a HUGE help so far. most of the packages for PHP are underdeveloped, so I'm rolling my own bsky auth for it (...for rolling my own appview) and boy is there a lack of walkthroughs out there that don't operate with the assumption that you have a client library that just works! I'm still trying to get the PAR request to work but this is way farther than I was yesterday.

In designing a location format containing anything other than lat/lon data, time plays an essential role, and needs to be be designed in from the beginning - at what time (or time interval) does the location description hold. For example street names can change, or there can be finer changes - the street of a house I used to live in had all of its addresses renumbered at some point. The business at a location can change while the building remains the same. For example the Elm City Diner in New Haven CT was a long time greasy spoon. In 1981 new owners transformed it into an upscale dining spot with a pianist that kept that name. Even later it became an Indian restaurant called Tandoor. If I want to location tag photos of 1226 Chapel St, I should have at least 3 business options that don't conflict because they refer to different time periods. https://arnoldzwicky.org/2016/01/21/the-elm-city-diner/
