Hello everyone, This is my first post to the list, which I've just joined, but I've been a mapper for a few years and some of you might remember me as compere at last year's State of the Map.
Yesterday, I met with the W3Cs' "data on the web best practice" working group. At their request, I gave a talk on the use of URIs (particularly linked data URIs) and related tags, in OSM. I described, and we then discussed, how we tag entities in OSM, using UIDs but not necessarily URLs, and issues facing data users who need to resolve those UIDs back to URLs; for example: openplaques_plaque = 1536 to: http://openplaques.org/plaques/1536 To that end, I've just modified [[Template:KeyDescription]] by adding two parameters: https://wiki.openstreetmap.org/w/index.php?title=Talk:Tag:historic%3Dmemorial&diff=prev&oldid=1010411 for "website" and "url_pattern"; see: https://wiki.openstreetmap.org/wiki/Key:openplaques_plaque of an example of how they're intended to be used (the label display needs tweaking). The model used there fails with Wikipedia links, expressed as "en:Example", because the equivalent URL is <https://en.wikipedia.org/wiki/Example>. Any suggestions for dealing with that? They were very impressed with the inclusion of Wikidata IDs <https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Wikidata> The sooner we move that from "Talk:Proposed_features/" to "Key:", the better. Other issues which are unhelpful to data re-users include keys with missing documentation; redundant keys ("Key:openplaques_plaque" vs "Key:openplaques_id"); ambiguous keys ("ref=1234" - ref in whose database?) and the perennial problem of the lack of stable URIs for entities in OSM. I have yet to solve that one... -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
