This document describes a vocabulary; in this case ODALA Air & Water - Core (Vocabulary). A vocabulary is a collection of reusable terms, more precisely classes and properties, of which their semantics is fixed by means of a label and a definition. For terms defined in this domain additional formal agreements may be defined. The formal agreements for external terms, reused in this domain, are adopted from that external source.
Summary
The ODALA Air & Water - Core vocabulary provides terminology to describe Observations in general.
Many terms were reused from existing standards, ie ISO 19156 Observations and Measurements and the OGC/W3C Semantic Sensor Network Ontology. Some useful properties were added to existing classes, eg ObservationCollection.metadata or Observationprocedure.specification.

This document is an official specification of a vocabulary and provides a partial conceptual framework for certain concepts. This specification is used to specify the definition, usage, domain and range of the RDF terms within this domain. The terms defined in this vocabulary are persistent and will as result of this never disappear, neither will the definitions change except to further clarify. Terms can over time be marked as deprecated and be replaced in newer versions of this specification.
1. License
This specification of Informatie Vlaanderen is published under the license: "Model license Free Reuse - v1.0".
2. Conformance
An exchange of data, in whatever way the data exchange happens, is compliant with this vocabulary if the terminology (classes and properties) is used in such a way that it is consistent with the semantics defined in the latest version of the specification ( domain, range, definition and usage) and when no terminology out of other vocabulary is used as alternative for terminology that is defined in this vocabularium.
