QoS Capabilities extension
• The challenge: Auto-discover the Quality of Service levels
of OGC Web Service instances.
– Is this service even meant to be reliable / operational?
• The solution: Declared best estimate/SLA to communicate
to the users:
• Availability (24/7, office hours, best effort, beta/test, regular
maintenance)
• Expected performance (max. response time) for stated, representative
operations & parameters (layer/feature type, CRS, format).
• Capacity (number of simultaneous requests happily served)
• Inline with the INSPIRE QoS service metadata
requirements.

QoS Capabilities extension
• The goal: Enable client software, QoS monitoring tools,
geoportals & catalogs to auto-discover the expected QoS
level of the services.
• Suggested approach:
– Leverage Capabilities extensions of existing standards (WMS,
WMTS, WFS, WCS, SOS, others?).
– Verify the feasibility in OGC Testbeds & other real-world
interoperability testing projects.
– Engineering reports, best practice documents etc.
– Eventually OGC standardization via the extension mechanism of the
existing OGC standards.
• Expectation management & building user trust in the
online Spatial Web Services.

More ideas welcome!
• OWS Monitoring API?
– A standardized way to access service metrics data from any OGC
Web Service to enable plug&play centralized SDI monitoring.
• Generic heath check (up/down)
• Technical remote monitoring (computing resources, DB connections
etc.)
• Recent usage statistics (request rate, number of successful / failed
requests
– Recommend a limited set of existing & well-known
authentication/authorization mechanisms to be used.
– Would require additional operation(s) to existing standards, thus
probably a longer term activity.
