Web mapping service link edit
Originally proposed at Wikidata:Property proposal/Creative work
Description | Link to the external service, where the image or map can be retrieved as a zoomable resource |
---|---|
Data type | URL |
Domain | image, map |
Allowed values | URL |
Example 1 | MISSING |
Example 2 | MISSING |
Example 3 | MISSING |
Planned use | This property can be used to link to resources where an image or map is available as a zoomable resource |
- Motivation
It will be possible to link to resources where the map items (also images) can be found as zoomable tiles. Susanna Ånäs (Susannaanas) (talk) 10:04, 4 November 2016 (UTC)

Protocols Supported edit
If this property is used, it should have a qualifier of any of the following types:
- Web Map Service (Q974922)
- Web Feature Service (Q2296308)
- Tile Map Service (Q1280407)
- Web Map Tile Service (Q10908558)
- Keyhole Markup Language (Q79587)
>> Any other? --Batje (talk) 11:36, 4 November 2016 (UTC)
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
- PXX: Wikipedia Mapwarper Id
- P131: Existing one, or new 'Wikidata Property for Web Mapping Service'
- PXXA: http://warper.wmflabs.org/maps/tile/$1/{z}/{x}/{y}.png
- PXXB: http://warper.wmflabs.org/maps/wms/$1?request=GetCapabilities&service=WMS&version=1.1.1
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

- Oppose as the proposal seems to be incomplete with no apparent interest at the moment in determining what structure is desired. Thryduulf (talk) 16:37, 22 April 2017 (UTC)
- @Susannaanas: You never entered an example. Does that mean that you don't need this property and the proposal can be closed? ChristianKl (talk) 10:08, 24 May 2017 (UTC)
- I would need input from the community to the above questions. It can also wait until later, when it's more articulated. – Susanna Ånäs (Susannaanas) (talk) 10:26, 24 May 2017 (UTC)
- Oppose, per Thryduulf. --Yair rand (talk) 21:28, 31 August 2017 (UTC)
- @Susannaanas, Yair rand, Thryduulf, Batje, Pasleim: I set it to "Not done" given that there are still no examples. If you have renewed interest feel free to create a new proposal. ChristianKl (talk) 10:06, 30 October 2017 (UTC)
