AgendaAgenda

JustificationJustification

• OGC member interest• WMO-CHy interest (Bruce Stewart)

– “Can you do this thing which we don’t seem to be able to do ourselves”– Help with methodology & continuity, process

• Hydrology has strong X-Domain requirements• Clear relationship with other OGC activities

– SWE– GALEON

• Domain modelling exemplar• Help generate reference model/best practice for framework datasets• Can the OGC methodology develop a product which is adoptable by an

international authority?

• How is this all different to a conventional OGC DWG?• Coordination & community representation• Do we need a different kind of WG within OGC?



Charter issuesCharter issues

• Joint committee with CHy– Explicitly reserve co-chair for WMO CHy nominee

• Visible linkage to WMO is evidence to the community that this activity has a plausible mandate

– Co-branded specifications?

• DWG– Charter to note that will make regular reports to ESS + tech working groups

• Allow for participation of non-members of OGC

• and/or an OGC Interoperability Experiment

• (Side effect: Hydrology as an exemplar of a methodology which contributes to development of a SDI design and maintenance process)
