1 GeoNetwork, The Open Source Solution for the interoperable management of geospatial metadata Ing. Simone Giannecchini, GeoSolutions Ing. Emanuele Tajariol, GeoSolutions

2 Outline GeoNetwork Introduction History Software Features Standards Architecture User Interface INSPIRE RNDT

3 (GeoSpatial) Catalog GeoNetwork Registry of Metadata Repository Enterprise Search Appliance GeoPortal SDI entry point Information Broker Metadata Editor Standards Based Implemented with Java Enterprise technologies

4 Java Enterprise Technologies Apache Lucene for speed light search Support for different backends MYSQL, Oracle, Postgresql, etc.. XSL Templates for flexible presentation XML Schema Metadata Validation and Editing Support for Enterprise Security LDAP Shibboleth

5 Standards ISO TC : : : : : /Z39.50 OGC CSW (ISO Profile) INSPIRE Discovery Service Others FGDC OpenSearch Geo RSS/GeoRSS WebDAV OAI-PMH Dublin Core

6 GeoNetwork: features (1) Search capabilities to access local and distributed geospatial catalogues Up- and downloading of data, graphics, documents, pdf files and any other content type An interactive Web Map Viewer to combine Web Map Services from local and distributed servers around the world On-line editing of metadata with a powerful template system XSD schema and schematron validation of metadata Native support for international metadata standards Multilingual metadata support for the ISO19115/19119/19110

7 GeoNetwork: features (2) INSPIRE advanced search option Data and metadata export/import procedures Scheduled harvesting and synchronization of metadata between distributed catalogues (GeoNetwork, CSW, Z39.50, OGC WxS, WebDav, Thredds, OAI-PMH) Support CSW ISO Profile, OAI-PMH, Z39.50 protocols Administration of groups and users through Web interface Multi-lingual user interface Data updates dissemination via RSS news feeds and as GeoRSS

8 Standards Metadata ISO19115:2003, ISO19119:2005, ISO19110:2005, ISO19139:2007 FGDC, Dublin Core Export/Import RSS & GeoRSS newsfeeds XML + XSL Catalogue interfaces OGC CSW ISO Profile OAI-PMH Z39.50 Geo-OpenSearch GeoRSS WebDAV Web Mapping Client OGC standards for WMS, WMC Web Map Server (through GeoServer) WMS, WFS, WFS-t, WCS, KML COMMON LANGUAGES EXCHANGE FORMATS CATALOGUES/ WEB SERVICES

9 Architecture Frontend - UI Search Edit View map Lucene index Metadata registry Spatial data repository GeoServer

10 Manage, Publish and Search collections of metadata about Data, Services and related information ISO Metadata about Data ISO Metadata about Services Enterprise Unique entry point Act as a Broker (SOA) Can work in federation Multilingualism Registry

11 Repository GeoNetwork can be used as a repository for the data it describes Authorization on data are independent from authorization on related metadata Easy-to-use editor controls to upload data and set automatically the onlineresource URL

12 Registry - Federation Multiple Registries for Multiple Enterprise Clouds Different data/services Different Organizations Federation reduces complexity Available Paradigms Harvesting Synchronized Local Copy of remote Metadata Remote Search Federating node as NoCache proxy for queries GeoNetwork supports both

13 GeoNetwork OGC Portal Reference Architecture

14 Architecture Desktop and server versions running on any platform Windows, Linux, Mac OSX Java Application using XML+XSL Lucene (Apache Project for XML file indexing) Jeeves (Open Source project for XML DB interface) GeoNetwork McKoi (Desktop), MySQL, Oracle Java Application Template XSL Jetty (Desktop), Tomcat DB Indexing Lucene Jeeves (DB XML)

15 Metadata harvesting Multiple paths to same source Loops GeoNetwork Nodes Hierarchical harvesting

16 Enterprise GeoPortal User Friendly Search/View GeoPortal Customizable Presentation Search Forms Results Presentation Based on XSL templates Embedding in third party sites Integrate with A&A layers Different views for different roles Metadata Profiling

17 Enterprise GeoPortal Metadata Profiling Authentication Internal user management for smaller deploys LDAP integration Shibboleth integration (federated SSO) Authorization User groups (grants on metadata) - customizable User profiles (grants on operations) - fixed Metadata access authorization is fine grained at group level

37 Metadata Editor Additional capabilities Extensible Templates set Visual Validation Extensive online resource management (WMS, File download, etc..) Additional Metadata Linking (dataset/service, parent/child, feature catalog/dataset metadata) Role assignment for presentation profiling Multilingual Support Batch Import/Insert from XML

38 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

39 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, and standards. Conformance to the RNDT metadata standard should ensure conformance to INSPIRE guidelines

40 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
