Move from String ID to numeric ID

The current ID format relies on a component of the URL, but the identifier for the marker is a numeric format. From the Example example ID "fort-ouiatenon" the ID for the marker from the Indiana Government and displayed on the website is "79.1998.2". While an id for linking to the record on the website is needed the ID used to resolve with external data is the numeric format and should be captured as well. Should this numeric ID be captured in a new property? Wolfgang8741 (talk) 20:21, 27 February 2022 (UTC)

Proposal created for separate numeric ID. Wolfgang8741 (talk) 17:15, 31 March 2022 (UTC)
