CEN/TC 287/WG 5 - Spatial Data Infrastructure

This part of the Technical Report provides guidance for validation and testing of data, metadata and services, as the main Spatial Data Infrastructure (SDI) components defined in other parts of CEN/TR 15449.
The guidance is given by means of examples of the validation and testing process required to assure conformance with the requirements existing in the relevant standards and guidelines.

This Technical Report describes a service-centric view of a Spatial Data Infrastructure (SDI).
The Service Centric view addresses the concepts of service specifications, the methodology for developing service specifications through the application of the relevant International Standards, and the content of such service specifications described from the perspective of the five Reference Model of Open Distributed Processing (RM-ODP) viewpoints:
-   the enterprise viewpoint addresses service aspects from an organisational, business and user perspective;
-   the computational viewpoint addresses service aspects from a system architect perspective;
-   the information viewpoint addresses service aspects from a geospatial information expert perspective;
-   the engineering viewpoint addresses service aspects from a system designer perspective;
-   the technology viewpoint addresses service aspects from a system builder and implementer perspective.
The intended readership of this Technical Report is those people who are responsible for creating frameworks for SDI, experts contributing to INSPIRE experts in information and communication technologies and e-government that need to familiarise themselves with geographic information and SDI concepts, and standards developers and writers.

This part of the Technical Report provides a reference model for a Spatial Data Infrastructure (SDI). It covers framework standards and identifies the relevant standards, technical specifications, technical reports and guidelines.
This part of the Technical Report provides a context model for the other parts of this Technical Report applying general architecture standards.
The intended readership of this Technical Report are those people who are responsible for creating frameworks for SDIs, experts contributing to INSPIRE, experts in information and communication technologies and e-government that need to familiarise themselves with geographic information and SDI concepts, and standards developers and writers.

This Technical Report identifies the standards, technical specifications, technical reports and guidelines, required to implement a Spatial Data Infrastructure (SDI) in Europe. It gives recommendations as to whether any of these items should become EN, and proposes a roadmap for future work items. It further provides recommendations for measures to be taken in order to support implementation and maintenance of a SDI. In so doing, the report addresses a range of topics, including:
-   multi-lingual aspects,
-   consistent identification of geographical items,
-   conformance testing,
-   geographic information metadata including catalogue service profile and guidelines, and
WMS and WFS profiles and guidelines.
