IRIDL Data Structures and Terms M. Benno Blumenthal class containing Data Library semantics. Connected with iridl:hasSemantics to iridl:Content. Intent is to have a search interface display the semantic structure associated with any given group of content, i.e. hasSemantics tells the interface which semantics are associated with the Content, and the class structure within iridl:Semantics tells the interface how to organize (and thus present) the semantics. Distinguishing Characteristics This is the starting point for a search interface to display the semantics associated with a given subset of the iridl:Content, i.e. the search interface organizes and displays individuals of this class (and its sub-classes).

These are ontologies of mostly datatype properties, so that sets of properties can be extracted to output within a particular convention set. rdfs:isDefinedBy connects these ontologies and their properties. These are the tools used to work with the metadata in this context. 1 OpenGIS Feature Feature This is the topmost point for the Data Library Metadata. The two major sub-classes are Content (datasets, variables, and documents) and Semantics (information about the Content used to organize it). 1 Class to ensure that a dataset with referenceDocumentation or with variables will be a term:SearchItem. Nino Indices Quantity Class to define semantic objects that are defined within datasets This property is used to connect programs to their output files for files that are generated programatically This is the property that connects Data Library Content to Data Library Semantics. Spatial Resolution This property is used to connect properties to the Metadata_Tools that understand them, i.e. the tools make special (i.e. semantic) use of the linked properties.
