ANNEX II ‘ANNEX VI IMPLEMENTING RULES FOR THE INTEROPERABILITY OF INVOCABLE SPATIAL DATA SERVICES PART A Additional Requirements on Metadata Set Out in Regulation (EC) No 1205/2008 1. Conditions applying to access and use The technical restrictions applying to the access and use of the spatial data service shall be documented in the metadata element “CONSTRAINT RELATED TO ACCESS AND USE” set out in Regulation (EC) No 1205/2008. 2. Responsible party The responsible party set out in Regulation (EC) No 1205/2008 shall at least describe the custodian responsible organisation, corresponding to the Custodian responsible party role set out in Regulation (EC) No 1205/2008. PART B Metadata Elements 3. Coordinate Reference System Identifier Where appropriate, this is the list of coordinate reference systems supported by the spatial data service. Each supported coordinate reference system shall be expressed using an identifier. 4. Quality of Service This is the minimum quality of service estimated by the spatial data service responsible party and expected to be valid over a period of time. 4.1. Criteria These are the criteria to which the measurements refer. The value domain of this metadata element is as follows: 4.1.1. Availability (availability) It describes the percentage of time the service is available. 4.1.2. Performance (performance) It describes how fast a request to the spatial data service can be completed. 4.1.3. Capacity (capacity) It describes the maximum number of simultaneous requests that can be completed with the declared performance. 4.2. Measurement 4.2.1. Description It describes the measurement for each criterion. The value domain of this metadata element is free text. 4.2.2. Value (value) It describes the value of the measurement for each criterion. The value domain of this metadata element is free text. 4.2.3. Unit (unit) It describes the Unit of the measurement for each criterion. The value domain of this metadata element is free text. PART C Instructions on Multiplicity and Conditions of the Metadata Elements The metadata describing an interoperable spatial data service shall comprise the metadata elements or groups of metadata elements listed in Table 1. Those metadata elements or groups of metadata elements shall be in accordance with the expected multiplicity and the related conditions set out in Table 1. When no condition is expressed in relation to a particular metadata element, that element shall be mandatory.
