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.
