The WMO Logical Data Model is intended to support the entire scope of WMO concerns: weather, climate and water. To reflect this scope, the WMO Logical Data Model is named 'Modèle pour l'Échange des informations sur le Temps, le Climat et l'Eau' (METCE). In English, it may also be known as the ‘METeorological Community Exchange’ model.<br /></p><p><br /></p><p>WMO METCE is intended to provide conceptual definitions of meteorological phenomena, entities and concepts in order to underpin semantic interoperability in the weather, climate and water domain.<br /></p><p><br /></p><p>The «Application Schema» includes:<br /></p><p><ul><li>specialisations of OM_Observation, OM_ComplexObservation and OM_DiscreteCoverageObservation classes (from ISO 19156)</li><br /></p><p><li>a concrete implementation of OM_Process (from ISO 19156)</li><br /></p><p><li>a number of meteorological feature types and categorisation schemes thereof.</li><br /></p><p></ul><br /></p><p>The 'WMO METCE' «Application Schema» will typically be imported to provide a baseline conceptual model framework upon which community-specific Application Schema are based.<br /></p>
