3 10 Jun 2008WIS Compliance Specifications of GISC, DCPC, and NC 3 Purpose and Authority: Purpose of WIS Specifications Existing centres within WMO Member States may apply for designation as one of the functional centres forming the core infrastructure of WIS: Global Information System Centre (GISC) Data Collection or Production Centre (DCPC) National Centre (NC) Designation requires a statement of compliance with required WIS functions, compiled by the Inter- Commission Coordination Group on WIS (ICG-WIS) The WIS Compliance Specification document provides technical specifications for required WIS functions

4 10 Jun 2008WIS Compliance Specifications of GISC, DCPC, and NC 4 Purpose and Authority: Authority of WIS Specifications On approval, the WIS Compliance Specifications will be the authoritative source for technical specifications of interoperable interfaces required of core WIS components across GISCs, DCPCs, and NCs It was expected that the WIS Compliance Specifications would be useful in an Invitation to Tender on software needed by a prospective WIS DCPC or GISC (e.g., the present European ITT for software to implement a Virtual GISC)
