Redesign of WebWerdis
Navigation structure / search functions
Internationalization
Integrate logging framework (necessary for monitoring)
Code clean-up
Integration with Geonetwork
Geonetwork
Customization of GUI

7. 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
Prototype 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

8. 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. 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

11. 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

13. 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)
AFD
Web-Service to manage and control AFD (in consideration)
Manage AtomFeed (in consideration)
Subscription Management
Controller: time and event triggered management (still under work)
Customization according to GISC-to-GISC backup necessary
