OGC OCEANS IE

• Approved December 2006 by OGC
• Initiated March 2007
• Evaluate and compare SWE/SOS/TML and WFS
  specifications for efficacy in distributing
  sensor data
• Provide example code and cookbooks to assist new
  implementers
• Built on the experience/expertise already derived
  in OOSTethys
• Allowed quick-start of the project

OGC OCEANS IE

• Plan
• Develop several SOS services
• acceptable sensor descriptions/schemas
• support measurements of
• Salinity
• Temperature
• Others (as we determine what they are)?
• Servers... and Clients
• Document development
• Provide data to potential developers

OGC OCEANS IE

• Data are accessible as graphical objects on a map

• http//www.openioos.org/testbed/sos/
• Data are accessible as text/table
• Data are available as time-series presentations

OGC OCEANS IEObservations Query Support

• WFS
• Version 1.1
• Bounding Box getFeature
• lat long lat lon z
• Procedure (requires workaround)?
• Observed Property (requires workaround)?

• SOS
• Version 1.0
• getObservation
• lat lon lat lon z
• time instance/interval
• time interval min only
• time interval max only
• Procedure and Obs. Property supported
• http post required

13
OGC OCEANS IE

• WFS requires schema creation/definition
• Maintenance, versioning, extensibility,
  standardization
• SOS requires adoption of a set of specifications
• time/learning curve to understand
  specifications/standards

14
OGC OCEANS IE

• End products
• Roadmap/procedures to implement specs used (SOS,
  WFS)?
• Prototype servers and clients developed
• Code available
• Reference implementations
• Cookbooks for developers
• Feedback results to OGC for specifcation
  update/improvement

15
OGC OCEANS IE

• Lessons learned
• Adopting standards is hard
• Need to involve science domain expertise
• Beats reinventing the wheel
• Long-term payback potential is better than
  one-offs
• Use of standards promotes innovation
