    • INSPIRE: about The INSPIRE directive aims to create a European Union (EU) spatial data infrastructure. This will enable the sharing of environmental spatial information among public sector organisations and better facilitate public access to spatial information across Europe. The INSPIRE directive came into force on 15 May 2007 and will be implemented in various stages, with full implementation required by 2019. Institutional site: http://inspire.jrc.ec.europa.eu/ GFOSS DAY 2013
    • INSPIRE: about  Infrastructure for Spatial Information in the European Community    Implementing Rules and Technical Guidance to implement EU-wide Interoperable SDIs    IR are legally binding TC are not legally binding Main Aspects Covered       2007/2/EC Directive, 14/03/2007 Fully in place by 2019 Metadata Network Services Data and Service Sharing Data Specification Monitoring and Reporting Maximum Reuse of existing standards (OGC, ISO, W3C) GFOSS DAY 2013
    • INSPIRE: Who does What   Discovery service  GeoNetwork View, Download, InvokeSD, Transformation Service  GeoServer GFOSS DAY 2013
    • INSPIRE: discovery services  Discovery of spatial dataset and services  Provide operations on services    query about service capabilities register other federated Discovery Services Provide operations on metadata    search update (both push and pull modes), perform federated searches  Based on Metadata specs from ISO  TG requires CSW 2.0.2 ISO AP as starting point GFOSS DAY 2013
    • INSPIRE: discovery services in GeoNetwork     GeoNetwork implements CSW 2.0.2 ISO Profile INPIRE extended constraints in metadata should be explicitly enabled in GeoNetwork Complies with almost all main requirements in Metadata Implementation and Discovery Services Main compliancy issues in:  Handling federated catalogues   Federated metadata retrieving   in Discovery Service Metadata and Link Discovery Service operations no CSW, only Z39.50 Publishing in pull mode  matching CSW Harvest operation in GN is not stable yet GFOSS DAY 2013
    • INSPIRE and ISO19115/19139 INSPIRE supported metadata are based on • ISO19115/19139 (metadata) • ISO19119 (services) There are some differences in constraints on metadata elements between ISO19115 and INSPIRE. The use of the INSPIRE guidelines to create INSPIRE metadata ensures that the metadata is not in conflict with ISO 19115. However, full conformance to ISO 19115 implies the provision of additional metadata elements which are not required by INSPIRE. GFOSS DAY 2013
    • INSPIRE support in GeoNetwork • Editing view that underlines INSPIRE required elements • Easy check and insertion of INSPIRE required elements • Schematron rules to check for INSPIRE conformance • Search using INSPIRE codelists • Extended CSW queryables fields to match INSPIRE requirements GFOSS DAY 2013
    • RNDT: about • RNDT («Repertorio Nazionale dei Dati Territoriali») is the Italian national metadata catalog - instituted in 2005 and managed by DigitPA - whose purpose is to facilitate the dissemination of the data of general interest, available in the public administration agencies at different levels. • RNDT is based on ISO19115, 19119 and 19139 standards. • Conformance to the RNDT metadata standard should ensure conformance to INSPIRE guidelines GFOSS DAY 2013
    • RNDT support in GeoNetwork GeoSolutions’ first work with RNDT was with a GeoNetwork customization for CSI Piemonte. Issues: • Some RNDT interpretations of ISO19139 differ from GeoNetwork standard implementation. • Some constraints in RNDT are looser than ISO19139 GFOSS DAY 2013
    • RNDT support in GeoNetwork Search on PSR thesaurus GFOSS DAY 2013
    • GeoNetwork 2.8 What’s new • Metadata versioning • Subtemplates • GeoServer publishing integration • Pluggable metadata schemas • Improved database connection pooling • Virtual CSW endpoints GFOSS DAY 2013
    • GeoNetwork 2.10 What’s new • Redesigned User Interface • Metadata profiles plugin support • New Admin UI GFOSS DAY 2013
