"link" element on the TileSetMetadata data structure #165

Closed doublebyte1 closed 8 months ago

doublebyte1 commented 8 months ago

On table 13 of the standard, the TileSetMetadata data structure has an element called "link"(singular), which contains links to related resources.

https://docs.ogc.org/is/17-083r4/17-083r4.html#toc22

Is it really "link" or "links", like in these implementations? https://maps.gnosis.earth/ogcapi/collections/blueMarble/map/tiles/WorldCRS84Quad?f=json https://test.cubewerx.com/cubewerx/cubeserv/demo/ogcapi/Daraa/collections/Daraa_mosaic_2019/tiles?f=json https://api.pdok.nl/lv/bag/ogc/v1_0/tiles/NetherlandsRDNewQuad?f=json

@doublebyte1 See the note in section 7.1 about how the logical model is mapped to actual property names in the JSON encoding:

In addition, all elements with multiplicity greater than one have names changed to plural. Please be aware of irregular plurals such as tileMatrix that changes to tileMatrices.

You can also see the actual property names including the plural links in the JSON Schema for TileSet metadata:

https://schemas.opengis.net/tms/2.0/json/tileSet.json

In XML, multiple singular < link > tags will be used.
