1. INSPIRE and
GEOSS Catalogues
Theory and Reality

2. You are forcing me to sin, because when using the
portal I always start cursing …
John, portal end-user

3. How to avoid it
• For end-users operating services are crucial
– Availability
– Quality of service / data / metadata
• Preparing catalogue of „clean services“ to ensure
availability
• First step - only WMS

4. Establishment of the catalogue
• Harvesting existing catalogues
• Catalogues CSW 2.0.2 ISO AP 1.0
• Only services (type=service)
• Periodically (P1D)
• Sources
– GEOSS registry
– INSPIRE geoportal
– Catalogues we know about
• Problems
– No central catalogue / we don’t know about services
– Classical search engines did not succeed
– Many catalogues do not response

6. Harvested catalogues
• ISPIRE national nodes: Austria, Belgium, Czech republic, Finland,
France, Germany, Luxembourg, Poland, Portugal, Slovakia,
United Kingdom
• CIDP
• EEA SDI
• ENVIROGRIDS
• EuroGEOSS
• GEOSS
• Habitats
• One Geology Europe
• Plan4all
• WHO

7. Service metadata
• Problems
– poor service metadata (missing abstract etc.)
– viewer or web page address instead of service
– no mandatory thematic classification in INSPIRE
– operatesOn broken links
– serviceType not clear

8. Testing services availability
• If Capabilities document is available and valid
• Periodically (P1D)
• Not valid services are set “hidden”, not erased
• Detect linkage in metadata
1. distributionInfo/*/transferOptions/*/onLine/*/linkage
http://myservice.com/wms?
SERVICE=WMS&REQUEST=GetCapabilities
2. distributionInfo/*/transferOptions/*/onLine/*/protocol
OGC:WMS-1.1.1-http-get-capabilities
3. identificationInfo /*/containsOperations/*/
connectPoint/*/linkage

9. Testing avalability of services
• Tools for service provider feedback
– RSS channel
– Automatic mail notification
– “Heartbeat” record
