6. Understanding WIS

7. WIS will provide three fundamental types of services Routine collection and dissemination service for time-critical and operation-critical data and products Data Discovery, Access and Retrieval service Timely delivery service for data and products

8. Understanding WIS Catalog of data and products Metadata standart Catalog of metadata Tools for metadata management Metadata synchronization DAR tools

9. From RTH to DCPC DCPCs will provide basic WIS functions: Metadata catalogues Internet portals Data access management Synchronization of metadata with GISC

10. From RTH to DCPC Analysis We need to build metadata catalog We already have web enabled services Data access management needs to be made WIS compliant

11. From RTH to DCPC Our approach Open source software File based metadata catalog Tool for metadata management Pull mechanism for metadata synchronization - OAI-PMH

12. From RTH to DCPC Metadata management

13. Future plans Upgrade of our RMDCN connection WIS portal at DCPC-Sofia Flexible system for metadata management that can be used by countries of our zone of responsibility Integration of data access management system with WIS portal to provide timely delivery service

14. Summary WIS implementation in DCPC-Sofia is one of the our most important activities. With help from WMO and GISC-DWD we learned what needs to be done and then technical part was relatively easy to be implemented.
