What is the unique ID of this property? edit

There are several ways of modeling this behaviour.

A. The URL is the key edit

That is the current proposal. This property becomes very flexible and can point to anywhere on the interwebs. There is not a lot of intelligence in this property, if the qualifier for the protocol (see below) of the link is ommitted, it becomes very error-prone.

B. The external qualifier is the key edit

This is similar to for example Bibliothèque nationale de France ID (P268) which requires every external resource to register as a seperate property, and then use the formatter URL (P1630) property to tell us more about the required format of the URL. Every of these P's could then have multiple formatter URL (P1630) for every protocol qualifier (WMS/WFS/etc.) it should create a new one.

C. The external qualifier *and* the protocol are the key edit

We create properties for every protocol, similar to formatter URI for RDF resource (P1921). Then, we go back to B, and create a Property for every service. Eg. The Mapwarper would have its own property:

  • PXXA: TMS URL
  • PXXB: WMS URL


Then the Wikidata Item for the map belonging to [ [File_dummy: New_haven_line_map.png] ] will have:

  • P18: File:New_haven_line_map.png
  • PXX: 1591
