Deprecation Notice

Notice: This convention has been deprecated due to IOOS’ transition from the OGC SOS/SWE suite of standards to ERDDAP for in situ data dissemination.

All relevant guidance in this standard has been superceded as of the 2020-01-10 publication date of the IOOS Metadata Profile 1.2. Please refer to the IOOS Metadata Profile for current guidance.
