Cover IR 84

[ilkkarinne]

The description of a layer shall use elements defined for the service capabilities in the [OGC 07-057r7] standard. This description shall specify the role of some parameters for the INSPIRE View Service as stated in the Regulation on INSPIRE Network Services [INS NS]:

Metadata elements	OGC WMTS standard elements of wmts:Layer
Resource Title	ows:Title
Resource Abstract	ows:Abstract
Keyword	ows:Keywords
Geographic Bounding Box	ows:WGS84BoundingBox
Unique Resource Identifier	ows:Identifier
Name	ows:Identifier
Coordinate Reference Systems	TileMatrixSetLink
Styles	Style
Legend URL	Style/LegendURL
Dimension Pairs	Dimension[@name,@units]

Resource Title, Abstract, Keyword, BBOX, CRS, Styles and LegendURL are covered by IRs 85 - 91. No explicit requirements for Name, Unique Resource Identifier or dimension pairs in the VS TG, but I suppose they must be given because they are made mandatory by the MD TG.

Note: possible misunderstanding with the Unique Resource Identifier: in the WMS profile it's interpreted as the identifier of the portrayed dataset (mapped with AuthorityURL and Identifier elements), but in the WMTS profile the ows:Identifier, identifying the layer by name, is used. The dataset name and the layer name may not be the same thing, as there may exist several layer portrayals for the same dataset/spatial data object.

Also it's not entirely clear if the Unique Resource Identifier or the metadata ID resolved by using the ows:Metadata URL should identify the layer. And if these two should match.

A unique ows:Identifier for each is mandatory by WMTS specification, so no explicit test for it is necessary.

It should be noted that there is a misalignment between the WMS and WMTS requirements here, as the Requirement 39 specifies the content of the layer names (using harmonized names as given in the data specifications), but for WMTS profile there are no requirements for the content of ows:Identifiers.

Chapter "5.2.3.3.4.5 UNIQUE RESOURCE IDENTIFIER" should be changed, as the INSPIRE metadata element "Unique Resource Identifier" should be used for identifying the underlying data set, not the layer itself. This the URI cannot be mapped to ows:Identifier, which is the layer name. Compare with the corresponding WMS requirement in chapter "4.2.3.3.4.5 UNIQUE RESOURCE IDENTIFIER"

LegendURL element is covered by the test A.08.IR91.layer.legend
