 Data Cube Vocabulary</a> provides a means to do this using the <a href="http://www.w3.org/TR/gld-glossary/index.html#rdf" target="_blank">Resource Description Framework (RDF)</a>. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations. The Data Cube vocabulary is a core foundation which supports extension vocabularies to enable publication of other aspects of statistical data flows or other multi-dimensional data sets.

+<h2>Conformance for Vocabularies</h2>
+A data interchange, however that interchange occurs, is conformant with a vocabulary if:
+
+<ul>
+<li>it is within the scope and objectives of the vocabulary;</li>
+
+<li>all classes and properties defined in the vocabulary are used in a way consistent with the semantics declared in its specification;</li>
+
+<li> it does not use terms from other vocabularies instead of ones defined in the vocabulary that could reasonably be used.</li>
+
+</ul>
+A conforming data interchange:
+<ul>
+ <li>may include terms from other vocabularies;</li>
+ <li> may use a non-empty subset of terms from the vocabulary.</li>
+</ul>
+A vocabulary profile is a specification that adds additional constraints
+to it. Such additional constraints in a profile may include:
+<ul>
+<li> a minimum set of terms that must be used;</li>
+<li> classes and properties not covered in the vocabulary; </li>
+<li> controlled vocabularies or URI sets as acceptable values for properties.</li>
+</ul>
