1 Sharing technology innovation: INSPIRE features of the open source project deegree Martin Seiler & Johannes Küpper & Jens Fitzke seiler

2 Outline The deegree project Implementation of OGC standards deegree and INSPIRE implementation Outlook & Summary

3 What is the deegree project? Java-Framework providing building blocks for SDI Main development goals provide uniform and comphrehensive framework for SDIs comprehensive OGC/ISO standard adherence OpenSource: LGPL (free to use) Base technology for many geoportals & SDIs, e.g. INSPIRE Geoportal...

4 Who is behind the deegree project? Started in 2000 as joint project between: University of Bonn lat/lon GmbH Since 2010 deegree is an official OSGeo project Community involvement SVN, Mailing-Lists, trac, artefactory, deegree-day, handbook,

5 Open Source Business Model Several companies offer development and consultancy services around deegree Idea: Provide general building blocks for SDI without license fees and offer customization consultancies tailoring

7 deegree and OGC standards OGC reference implementation Web Coverage Service Web Map Service Web Map Service Certified OGC compliant Sensor Observation Service Web Feature Service Implementing several more CSW (ISO AP, ebrim) GML...

8 lat/lon and OGC activities Since 2010 lat/lon GmbH is OGC principle member development of reference implementations in OWS-9 testbed Web Feature Service 2.0 Web Map Tile Service 1.0.0

9 Implementing INSPIRE: Theory WebServices Local Data INSPIRE Data WFS WMS CSW WPS

10 Implementing INSPIRE: Challenges Provide compliant Network Services: Discovery Service (CSW ISO AP +) View Service (OGC WMS ) Download Service (OGC WFS ) Encoding: GML Complexity: INSPIRE defines complex data models Transformation: National data needs to be transformed

11 Implementing INSPIRE the next step: Download Services Lessons learned from ESDIN (access to Annex I data) Many participants failed to produce valid WFS output INSPIRE model / representation is complex Limitations in WFS implementations Restrictions in internal model / storage

12 deegree 3 INSPIRE downloadservice Handles complex schemas out-of-the box, e.g. INSPIRE Data Themes (tested: Annex I) GeoSciML, XPlanung,... Configuration based on unmodified schemas Works with unmodified INSPIRE datasets National Data Extract Transform Load Valid INSPIRE GML deegree 3

13 INSPIRE featurestore configuration Abstraction layer as access point to features Backends: ESRI, PostGIS, GML instance documents, Access via WFS, WMS layer table driven s im p le m o d e ls GML schema dri ven complex m o d el s blob hybrid relational canonical custom deegree configuration configuration workflow sql feature store WFS

14 deegree 3 serving INSPIRE data deegree 3 WMS INSPIRE View Service INSPIRE Download Service WFS WFS-T INSPIRE Data Sets INSPIRE Feature Store PostGIS Oracle SQL Server Loader

15 deegree 3 downloadservice feature highlights Support of INSPIRE Download Service Specification WFS / 1.1.0, WFS-T + XLink profiles GML 2 / 3.0 / 3.1 / 3.2 output / input ISO 19107: Supports complex geometries Full XPath 1.0 support in filters On-the-fly coordinate transformation Streaming architecture High scalability

16 deegree 3 viewservice feature highlights Support of INSPIRE View Service Specification WMS / (CITE-tested) Rendering of complex datasets Sophisticated styling using SLD or SE 1.0 Streaming High scalability

17 deegree 3 discoveryservice feature highlights Support of INSPIRE Discovery Service Specification CSW (ISO AP 1.0.0) Fully transactional Pluggable 'metadata stores' allows to add support for new APs and backends Modular inspector architecture allows to validate records

18 Summary INSPIRE is a main driver for deegree development perfect match for INSPIRE services comprehensive support of complex application schemas tight integration of View and Downlaod Services highly scalability and performance Open Source share innovations try it! support it! sponsor it!

19 Outlook what's hot? WFS 2.0 reference implementation WMTS reference implementation documentation deegree day 2012 dedicated project conference November in Bonn contributions welcome!
