How to map a render service

[fabricebrito]

Problem:

The render extension provides a mechanism to use a render service and it defines a key and a tile.
The web-map-links extensions provides links to e.g. xyz services.

How can these two extensions join efforts to map a render definition to a "render" service?

Suggested solution

Extend the link with a key=value that maps the xyz link to a render element:

        {
          "rel": "xyz",
          "href": "https://view.iride-datalake.terradue.com/collections/sentinel-s2-l2a-cogs/items/S2B_MSIL2A_20231107T102139_N0509_R065_T32TNR_20231107T132337/tiles/WebMercatorQuad/{z}/{x}/{y}@1x?&assets=red&assets=green&assets=blue&color_formula=Gamma%20RGB%201.5%20Saturation%201%20Sigmoidal%20RGB%2010%200.3&rescale=1,6000&rescale=1,6000&rescale=1,6000",
          "type": "image/png",
          "title": "True colour composite visualized through a XYZ",
          "render": "rgb"
        },

where rgb in "render": "rgb" is a render definition
