The INSPIRE directive aims to create a European Union (EU) spatial data infrastructure. After Discovery Services (metadata catalogues) and View Services (map servers), the next big thing on the INSPIRE roadmap are Download Services. Download Services provide access to the geospatial base data of the member states. This presentation outlines the requirements and the successful implementation of compliant INSPIRE Download Services using FOSS. What are the differences between "Predefined Dataset and "Direct Access" Download Services? What are "non-interoperable" and "interoperable" Download Services? What are the Data Themes (Annex I-III)? When is harmonization of base data required and how to approach it in practice? After providing an overview on the formal requirements, the presentation will turn to the special features of the deegree WFS. This thorough implementation of the OGC WFS 2.0 standard has a special focus on smooth handling of rich data models, such as INSPIRE Data Themes. This includes a powerful relational mapping language and an alternative storage approach which guarantees efficient reconstruction of rich features from spatial SQL databases, such as PostGIS.
