8. Deutscher Wetterdienst DWD GISC Node - Current Status High level architecture: Metadata Management  DAR Catalogue  Did extensively Performance Tests (Geonetwork 2.2, terraCatalog 2.3)  DWD formulated test cases  Contracted external partner for tests  Functional Tests  DAR Generator / Importer  Developed DAR metadata generator (template driven architecture)  External review of DAR metadata  Developed DAR importer  Issues we identified during our work  Tested DAR catalogues fulfilled most, but not all INSPIRE and WMO requirements  DAR Metadata  Paper with Request for Clarification (JMA, CMA and DWD)  Schematron rules for validating WMO profile would be very helpful

9. Deutscher Wetterdienst DWD GISC Node - Current Status High level architecture: Metadata Management  Metadata Harvesting  CMA and DWD did several functional tests with OAI-PMH in 09/09  Different implementations of OAI-PMH could not harvest each other  Deleted metadata records: different implementations  Standard vanilla implementations modify harvested metadata  Ongoing tests between CMA and DWD  Started January 2010  Initial tests showed 1 record ~ 1 second  space for improvement  Backup strategy  Exchange of metadata files as products

10. Deutscher Wetterdienst DWD GISC Node - Current Status High level architecture: Metadata Management

11.

12. Deutscher Wetterdienst DWD GISC Node - Current Status HLA: GISC-to-GISC communication  Collaboration CMA and DWD  Memorandum of Understanding signed end of last year  Two Workshops held  GISC-to-GISC communication tests with CMA  CMA and DWD installed Blog solution and AFD solution  Data sets with appropriated time profile (issue warning during model transfer)  Blog solution  CMA and DWD did several improvements on publishing and polling components  Usage of tar minimize latency of transfer  Necessary to include size of “metadata” (AtomFeed) into calculation of transfer volume  Identified several further improvements like prioritization, AtomFeed handling, logging  JMA has provided a new improved solution in 10/2009  AFD solution  Average transport time between 4-5 sec during 24hour continuously test, warnings between 3-4 sec  In case of unsecured connection sometimes corrupted data occur

13. Deutscher Wetterdienst DWD GISC Node - Current Status HLA: GISC-to-GISC communication backup  Technical specification requires a bilateral agreement from 2 GISC for a backup scenario  CMA and DWD prepared proposal for priorities in DAR metadata  First common draft of dissemination metadata (XML schema)  Need to prove in practice

15. Deutscher Wetterdienst DWD GISC Node - Current Status High level architecture: Delivery components  Message Switching System  REST Web-Service to manage and control Moving Weather  First proposal for generic Interface  Integration into WebWerdis (still under work)  Subscription Management  Controller: time and event triggered management (still under work)  Customization according to GISC-to-GISC backup necessary

16. Deutscher Wetterdienst DWD GISC Node - Current Status Live Demonstration

17. Deutscher Wetterdienst DWD GISC Node - Current Status TC 5 - Maintenance of Users, Roles, Authorization and Authentication  Search metadata  Access data  Show difference between authorized and unauthorized User  User and Customer management  Subscription  View historic transactions

18. Deutscher Wetterdienst DWD GISC Node - Current Status Metadata Management – TC 1  Show metadata editor  Fully integration open because of separation between Intranet and DMZ  Authorization required to add/modify/delete metadata

19. Deutscher Wetterdienst DWD GISC Node - Current Status Metadata Management – TC 2, TC 6  A WIS Centre provides new metadata records  Show that GISC Geonetwork doesn’t contains new metadata records  Show that GISC_PRODUCTS is empty  Copy new metadata records to remote provider, reindex  GISC harvests new metadata records  Update of GISC Geonetwork and jOAI Provider  Show update of Geonetwork with SRU query  Show update of GISC_PRODUCTS

20. Deutscher Wetterdienst DWD GISC Node - Current Status Challenges during the Implementation  Metadata generation  See paper “Questions on Metadata” from CMA, JMA and DWD from 11.2009  WIS Specification is open – what is good!
