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.
