Obtain Technical Details
• GEO DAB team gets in touch with SMHI technical
team
• SMHI provided service URL to be brokered (OGC
CSW)
Interoperability Tests: 1st Iteration
• GEO DAB tried to query the provided catalog via
HTTP POST requests (commonly implemented by
CSW servers)
– Failed
• GEO DAB tried to query the provided catalog via
HTTP GET requests
– Success
• Contacted SMHI team, which confirmed HTTP POST
is not allowed, keep using HTTP GET
Interoperability Tests: 2nd Iteration
• GEO DAB harvested the provided
catalog.
• GEO DAB team produced a test
report with the following
information:
– Discoverability Test Results:
• Number of harvested
resources
• Implementation Note about
the GET/POST requests
– Accessibility/Visualization
Tests:
• Tuning required
Before Tuning
• Original Access Information
– URL:
http://opendata-view.smhi.se/klim-stat_aska/wms?layers=blixtnedslag_1988
– Name: namn
– Protocol: HTTP:OGC:WMS
After Tuning
• Normalized Access Information
– URL:
http://opendata-view.smhi.se/klim-stat_aska/wms?
– Name: blixtnedslag_1988
– Protocol: HTTP:OGC:WMS
Interoperability Tests: Assessment
• GEO DAB team produced a new Test Report and a
short video
• GEO DAB team set up a dedicated test instance
• SMHI team accessed the test instance and verified
results
• SMHI team approved current implementation
• GEO DAB moved current implementatin to
production environment
