ICG-WIS: WIS Development Plan 2006 (I)

Prototype for CBS TECO on WIS (Nov 2006): GISC-Functions

– VGISC Portal (incl. authentication and [simple] authorisation)– Access to Metadata catalogue for

– data discovery– viewing/modifying (authorisation required) of dissemination control information

– Metadata import and export interfaces (WMO Metadata Standard)– Metadata harvesting from sample DCPCs (incl. Metadata translation [e.g. via OAI

mechanisms] if applied by a DCPC)– Data retrieval from the VGISC real-time database and the internal DCPCs and request

forwarding to sample DCPCs – Demonstration of GTS data acquisition/dissemination with sample NCs– Access to monitoring information

ICG-WIS: WIS Development Plan 2006 (II)

GISC-Cookbook: Requirements to be fulfilled for participation as WIS DCPC of existing data-collection or products centres

– Register as a DCPC with WMO;– Provide capability to deliver discovery-level metadata in standard XML in accordance

with WMO Core Profile (for those datasets whose existence you are willing to make globally known);

– Provide capability/interface for automatic harvesting of metadata (in WIS standard XML);– (Note: ICG-WIS & ET-WISC must define WIS protocol, access policies/control,

synchronisation, etc.)– Provide access to data through an on-line interface (via agreed protocols);

– Strive to provide data in at least one of several standard formats – or provide decoding software.
