step 2 question for deployment
Step 2 – Question for deployment
  • … Should WMO metadata from a WIS node get mixed in the same service as CAP?
  • Recommend to keep them separate so that CAP client software doesn’t get confused or need to filter between CAP messages and other WIS metadata documents

step 3 display of the area description
Step 3 – Display of the description?
  • This issue really belongs in the realm of the CAP client software that reads and displays the message.
step 4 aggregating other cap feeds
Step 4. Aggregating other CAP feeds
  • Registry of CAP Feeds
  • Harvest multiple feeds into a single CAP catalog
  • Provide distributed search of CAP feeds

summary
Summary

So where does that leave us? Were we successful in supporting CAP with Geoportal?

Yes … no programming needed, just custom configuration following the documentation.

Things to be continued and improved upon:

Customize search User Interface for the CAP-specific ontology

Improve tools for creating and displaying the union of the options
