This document discusses applying standard data models to environmental data streams from ocean observations. It presents examples of encoding oceanographic observation data using semantic web standards like the W3C Observation and Measurement ontology. These approaches aim to integrate live sensor data with linked open data to support interoperability across scientific domains.
