phenomenon.xsd A GML conformant schema for definitions of phenomena, per Annex C of OM specification Copyright (c) 2007 OGC, All Rights Reserved. For conditions, see OGC Software Notice - http://www.opengeospatial.org/legal/ Basic Phenomenon definition, and head of substitution group of specialized phenomenon defs. gml:description may be used for a more extensive description of the semantics, with a link to a definitive version (if available). gml:name should be used for the name or label. Note: In GML 3.2 the gml:identifier element should be used for the identifier assigned by or preferred by the data provider. This identifier will typically be in the form of a URN, for example following the OGC URN scheme e.g. urn:x-ogc:def:phenomenon:OGC:Age Basic Phenomenon definition, and head of substitution group of specialized phenomenon defs. A scalar Phenomenon is defined by adding constraints to an existing property. Property that forms the basis for generating a set of more refined Phenomena; e.g. Chemical Composition, Radiance Constraints that cannot be expressed as values of an orthogonal/helper phenomenon Constraint expressed as a value or range of an orthogonal/helper phenomenon Description of a scalar Phenomenon defined by adding constraints to a property previously defined elsewhere. Description of a set of Phenomena. CompoundPhenomenon is the abstract head of a substitution group of specialized compound phenomena The number of components in the tuple Description of a set of Phenomena. CompoundPhenomenon is the abstract head of a substitution group of specialized compound phenomena A Phenomenon defined as a set of explicitly enumerated components which may or may not be related to one another Optional phenomenon that forms the basis for generating more specialized composite Phenomenon by adding more components A Phenomenon defined as a set of explicitly enumerated components which may or may not be related to one another A phenomenon defined as a base property convolved with a set of constraints The set of constraints may be either * an explicit set of soft-typed measures, intervals and categories * one or more lists of soft-typed measures, intervals and categories * one or more sequences of soft-typed measures and intervals Phenomenon that forms the basis for generating a set of more refined Phenomena; e.g. Chemical Composition, Radiance A set of values of some secondary property that constraints the basePhenomenon to generate a Phenomenon set. If more than one set of constraints are possible, then these are applied simultaneously to generate Other constraints are described in text A phenomenon defined as a base property convolved with a set of constraints The set of constraints may be either * an explicit set of soft-typed measures, intervals and categories * one or more lists of soft-typed measures, intervals and categories * one or more sequences of soft-typed measures and intervals
