2 Conformance
2.1 Overview This standard has been written to be compliant with the OGC Specification Model – A
Standard for Modular Specification OGC 08-131r3. Extensions of this standard should themselves be conformant to the OGC Specification Model.
This standard defines conceptual models and an XML implementation of these models for describing non-physical and physical processes surrounding the act of measurement
and subsequent processing of observations. The conceptual models are described using UML while the implementation is described using the XML Schema language and
Schematron. It is envisioned that OWL Web Ontology Language and RDF Resource Description Framework versions could also be generated from the models if deemed
useful and desired.
2.2 Specification identifier All requirements-classes and conformance-classes described in this document are owned
by the specification identified as
http:www.opengis.netspecsensorml2.0 .
2.3 Conformance classes The conformance rules are based on XML validation using the XML Schema
representation of SensorML, together with processing of constraints expressed using Schematron assertions and reports.
Conformance with this specification shall be checked using all the relevant tests specified in Annex A. The framework, concepts, and methodology for testing, and the criteria to be
achieved to claim conformance are specified in ISO 19105: Geographic information — Conformance and Testing. In order to conform to this OGC™
encoding standard, a standardization target shall implement the core conformance class, and choose to
implement any one or more of the other conformance classes. The conformance rules for the XML implementation are based on XML validation using
XML Schema representation of SensorML, together with processing constraints expressed using Schematron assertions and reports.
