Article 7Monitoring of the accessibility of metadata through discovery services
1.The following indicators shall be used to measure the accessibility of metadata for the spatial data sets and services corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC through the discovery services referred to in Article 11(1)(a) of that Directive:
(a)a general indicator (NSi1), which measures the extent to which it is possible to search for spatial data sets and spatial data services corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC on the basis of their corresponding metadata through discovery services;
(b)the following specific indicators:
NSi1,1, which measures the extent to which it is possible to search for spatial data sets corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC on the basis of their corresponding metadata through discovery services;
NSi1,2, which measures the extent to which it is possible to search for spatial data services corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC on the basis of their corresponding metadata through discovery services.
2.Member States shall determine, for each spatial data set and spatial data service mentioned on the list referred to in Article 2(1), whether a discovery service exists and shall attribute to the data set or service the following values:
(a)value 1 where a discovery service exists;
(b)value 0 where no discovery service exists.
3.Member States shall calculate the general indicator NSi1 by dividing the number of spatial data sets and spatial data services corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC for which a discovery service exists, by the total number of spatial data sets and spatial data services corresponding to themes listed in those Annexes.
4.Member States shall calculate the specific indicators as follows:
(a)the number of spatial data sets corresponding to the themes listed in Annexes I, II and III to Directive 2007/2/EC for which a discovery service exists, divided by the total number of spatial data sets corresponding to themes listed in those Annexes (NSi1,1);
(b)the number of spatial data services corresponding to themes listed in Annexes I, II and III to Directive 2007/2/EC for which a discovery service exists, divided by the total number of spatial data services corresponding to themes listed in those Annexes (NSi1,2).
