TG View - Data-service linking simplification for WMS

[heidivanparys]

Change proposal description

This change proposal is the outcome of the work done in https://github.com/INSPIRE-MIF/gp-data-service-linking-simplification/ that relates to the WMS implementation in the TG View.

Addressed TG

Technical Guidance for the implementation of INSPIRE View Services

Location

Section 4.2.3.3.1. View service metadata

Issue faced

Section 4.2.3.3.1. View service metadata has to be updated to contain a third scenario, in which the View Service metadata elements are published in the WMS capabilities without using the ExtendedCapabilities part.

Proposed solution

Update Implementation Requirement 6 to give the choice between the three scenarios, and make it refer to table 3(a) and a new table 3b, meaning that Implementation Requirement 6 will tell how the INSPIRE metadata elements shall be mapped. This also means that the subsequent requirements requiring a certain mapping are redundant. Therefore, only the subsequent requirements that set requirements for the value of the metadata element are kept.

• Update: req 6, 8, 11, 14, 15, 16, 20, 24, 26, 27, 29
• Remove: req 7, 9, 10, 12, 13, 17, 18, 19, 21, 22, 23, 25, 28, rec 3.
• Add table 3b, rename table 3 to table 3a.

Impact on IR

No impact.

Impact on INSPIRE validator

This affects Conformance class: INSPIRE Profile of WMS 1.3.0 / ISO 19128. The validator will have to take the 3rd scenario into account. The division in different tests can be kept, many of them have to be changed

• to reference req 6 instead of one of the proposed removed requirements
• to take the 3rd scenario into account

Regarding the approach:

The alternative would be to update each requirement in 4.2.3.3.1. View service metadata to take scenario 2 and 3 into account, that would be rather unmanageable and overwhelming, I think. In addition, the proposed approach is equivalent to the approach that has been taken for WFS, see TG Requirement 53 in 6.6. Publishing INSPIRE metadata using ows:ExtendedCapabilities.
