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

Data are accessible as graphical objects on a map http://www.openioos.org/testbed/sos/gm_sos.html http://www.openioos.org/testbed/sos/
Data are accessible as text/table Data are available as time-series presentations

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

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-
off’s” Use of standards promotes innovation
