12 Putting information into WIS 12

13 Discovery, Access, Retrieval User Searches catalogue at Asks / for product 2 1 Passes WIS metadata to Passes product to user

14 Metadata records To do this we need to know about the data sets 14

15 WIS Discovery Metadata Dataset title Dataset reference date Dataset responsible party Geographic location of the dataset Dataset topic category Dataset descriptive keywords Abstract describing the dataset Distribution format Online resource Dataset language Dataset character set Spatial resolution of the dataset Additional extent information for the dataset (vertical and temporal) Spatial representation type Reference system Lineage Other constraints Metadata file identifier Metadata standard name Metadata standard version Metadata language Metadata character set Metadata point of contact Metadata date stamp 15

16 WIS and WIGOS metadata WIS What information is available? How can I get it? What format is it in? Who owns it? Who is allowed access? Which observing sites included WIGOS What observation sites are there? Where are they? How do they make observations? What is the environment like around them? Who is responsible for them? Where can I find actual observations 16

17 Reference information 17

18 Useful references Resource WIS Manual (WMO-No 1060) Guide to WIS (WMO-No 1061) List of s (links to their catalogues) Manual on GTS (WMO-No 386) Manual on Codes (WMO-Mo 306) Traditional Alphanumeric Codes Table Driven Code Forms Codes derived from data models Location
