4.2 Measurement
Set of operations having the object of determining the value of a quantity [OGC 10-004r3ISO 19156].
4.3 Observed Property
Facet or attribute of an object referenced by a name [OGC 10-004r3ISO 19156] which is observed by a procedure.
4.4 Observation
Act of observing a property [OGC 10-004r3ISO 19156].
4.5 Observation Offering
An Observation Offering groups collections of observations produced by one procedure, e.g., a sensor system, and lists the basic metadata for the associated observations including the observed
properties of the observations.
4.6 Procedure
Method, algorithm, instrument, sensor, or system of these which may be used in making an observation. [OGC 10-004r3ISO 19156]
NOTE: As the definition of procedure states, this standard uses that term as a generalization of, for example, the terms sensor and sensor system, but also for simulations or other calculations that may produce observations.
4.7 Sensor
Entity that provides information about an observed property as its output. A sensor uses a combination of physical, chemical or biological means in order to estimate the underlying
observed property. At the end of the measuring chain electronic devices produce signals to be processed. [OGC 06-021r4]
4.8 Sensor System
System whose components are sensors. A sensor system as a whole may itself be referred to as a sensor with an own management and sensor output interface. In addition, the components of a
sensor system are individually addressable. [OGC 06-021r4]
5 Conventions
5.1 Abbreviated terms
Most of the abbreviated terms listed in Subclause 5.1 of the OWS Common Implementation Specification [OGC 06-121r3] apply to this document, plus the following abbreviated terms.

5.2 UML notation
Diagrams that appear in this standard are presented using the Unified Modeling Language UML static structure diagram, as described in Subclause 5.2 of [OGC 06-121r3].
NOTE Packages and data types from foreign namespaces are shown with grey background.
5.3 Platform-neutral and platform-specific standards
For compliance with Clause 10 of [OGC Topic 12] and [ISO 19119], this standard follows the pattern defined in Subclause 5.4 of [OGC 06-121r3]. That is, model elements are specified in
platform-neutral fashion first, using tables that serve as data dictionaries for the UML model see Subclause 5.4 of this document. Platform-specific encodings of these model elements are
provided in separate clauses or documents.
The XML Schema encoding has automatically been generated using the mapping rules defined in [OGC 09-001].
This document specifies a platform-specific encoding for a SOAP operation binding and a KVP binding over HTTP. The model as well as its XML Schema encoding and other data can also be
used to create other bindings such as a RESTful or POX Plain Old XML over HTTP using plain XML.
5.4 Data dictionary tables
The UML model data dictionary is specified herein in a series of tables. The contents of the columns in these tables are described in Table 1 of [OGC 06-121r3].
5.5 Classes imported from other specifications with predefined XML encoding
