3. HMA-T Progress Meeting 26 November 2008 Objectives  01- enabling support of HMA catalogs in GI-cat “COTS and/or Open Source Component Implementation and Test” of the SoW referring to the GI-CAT open-source catalogue middleware and the HMA catalogue interfaces (06-131, 07-038)  02- CITE tests “Conformance Testing” of the SoW referring to the GI-CAT open- source catalogue middleware and the HMA catalogue interfaces Implementation of conformance test scripts compatible with the OGC CITE initiative Slide 3

4. HMA-T Progress Meeting 26 November 2008 Work performed  Objective 01- enabling support of HMA catalogs in GI-cat Analysis of possible GI-cat extension strategies Design of support for OGC 06-131 Design of support for OGC 07-038 Slide 4

5. HMA-T Progress Meeting 26 November 2008 GI-cat overview  A framework to federate catalog, inventory and access heterogeneous standard services  International standards: OGC CS-W, WCS and WMS  Community standards: UNIDATA THREDDS/OPeNDAP catalog service, the CDI/SeaDataNet (Common Data Index) and the GBIF (Global Biodiversity Information Facility) catalog service Standard catalog interfaces publication (CSW/ISO & CSW/Core) An extended SOAP catalog interface to enable user feedback, catalog configuration and incremental queries  Distributed queries, hierarchical data model, incremental queries, translucent and opaque services chaining, modular framework  Experimented and tested in different projects and initiatives including: SeaDataNet FP7 project; GEOSS IP3; GEOSS AIP Slide 5

6. HMA-T Progress Meeting 26 November 2008 Information view  GI-cat data model is based on the catalog information model described by “OpenGIS catalog Services Specification 2.0.2 – ISO Metadata Application Profile” [OGC 07-045] the standard used to describe geospatial metadata is “Geographic Information – Metadata” [ISO 19115:2003(E)] metadata definitions needed to describe a geoinformation service are specified in “Geographic Information – Services” [ISO 19119:2005/PDAM 1] standard Slide 6

7. HMA-T Progress Meeting 26 November 2008 Components view  Profilers: standard catalog interfaces publication; mediation to and from QueryManager  QueryManager: queries distribution  Accessors: queries carrying out by mediation to remote service; mapping to GI-cat data model Slide 7

8. HMA-T Progress Meeting 26 November 2008 Extending GI-cat  Strategies to support discovery and access of additional data models Mapping: a mapping is defined between the new data model entities and the GI-cat entities. Hence, the new data model is supported by the GI-cat model and can be queried in a convenient way GI-cat model extension: the new concepts coming from the additional model are added to the GI-cat data model through an extension point GI-cat model modification: the GI-cat data model is modified in order to accommodate the new concepts coming from the additional data model Slide 8

9. HMA-T Progress Meeting 26 November 2008 SUPPORT OF OGC 07-038 Extending GI-cat Slide 9

10. HMA-T Progress Meeting 26 November 2008 Extension strategy  In order to support the CIM data model in GI-cat, a strategy of mapping is chosen, considering that GI-cat model is based on the information model described in [OGC 07-045], that is ISO 19115 / 19119 compliant In particular the mapping described in Annex F of [OGC 07-038r1] can be used for reference Thus, CIM resources can be integrated into the existing architecture, ready to be served by the catalog Slide 10

11. HMA-T Progress Meeting 26 November 2008 Extended Components  An ebRIM-CIM Profiler component will map between the ebRIM-CIM and the GI-cat QueryManager.This task is reduced to a mapping of CIM resources to GI-cat resources  An extended QueryManager will support the ebRIM query semantics  An ebRIM-CIM accessor will be able to query the source data (e.g. CIM metadata stored locally) Slide 11

12. HMA-T Progress Meeting 26 November 2008 SUPPORT OF OGC 06-131 Extending GI-cat Slide 12

13. HMA-T Progress Meeting 26 November 2008 Data model extension details  An extension of Metadata object is added to the GI-cat data model to support the heterogeneous information coming from the EO Data Model  In this way the EO Products semantics is totally preserved. Queries can be performed directly on all available EO Products queryables and results will be presented according to the “EO Products data model” schema Slide 13

14. HMA-T Progress Meeting 26 November 2008 Two steps extension strategy 1. GI-cat data model extension: needed to fully accommodate the EO information in the GI-cat data model, a new extended type of Metadata is proposed (EOMetadata). GML EO data is mapped to it 2. Basic Mapping: a core mapping between EO and ISO 19115 is used for basic interoperability Slide 14 11 22

15. HMA-T Progress Meeting 26 November 2008 Extended Components  An ebRIM-EO Profiler component will forward the requests to the QueryManager and present the results  An extended QueryManager will support the ebRIM query semantics  An ebRIM-EO Accessor will query the source data (e.g. EO metadata stored locally) Slide 15

16. HMA-T Progress Meeting 26 November 2008 Work performed  Objective 02- CITE tests Specification of Abstract Test Suites  Based on Infoterra Guidance on defining an Abstract Test Suite (ATS) for EO Application Profiles of OGC specifications Test description and scope for HMA Catalogue Protocol OGC 06- 131 and HMA Catalogue protocol OGC 07-038 interfaces Test Cases definition, including  Identification of required and optional server functionalities in the interface, expected results  Explanation of an acceptable verification of the results  List of expected/valid warnings or exceptions to interface behaviour Slide 16

17. HMA-T Progress Meeting 26 November 2008 Work planned  [Dec2008] Identify test data necessary to conformance tests  [Jan2009] Implement and deploy ETS for the ERGO/Intecs TEAM engine for the following HMA Catalog Protocol interfaces  [Jan2009] Implementation of OGC 07-038 support in GI-cat  [Feb2009] Implementation of OGC 06-131 support in GI-cat  [Mar2009] Software test Slide 17

18. HMA-T Progress Meeting 26 November 2008 Issues  Availability of EO test data  Availability of CIM test data  Conformance levels definitions in OGC 06-131?  A single deliverable to OGC (one ATS) is recommended instead of having multiple “competing ones” [kick-off minutes]  ERGO/Intecs relationship with the official OGC CITE Slide 18
