0.2 jeni@jenitennison.com Vocabulary for multi-dimensional (e.g. statistical) data publishing dave@epimorphics.com The data cube vocabulary ian@epimorphics.com 2013-07-26 richard@cyganiak.de 2010-07-12 arofan.gregory@earthlink.net 2010-11-27 2013-03-02 This vocabulary allows multi-dimensional data, such as statistics, to be published in RDF. It is based on the core information model from SDMX (and thus also DDI). Data set Represents a collection of observations, possibly organized into various slices, conforming to some common dimensional structure. Measure property The class of components which represent the measured value of the phenomenon being observed Slice Denotes a subset of a DataSet defined by fixing a subset of the dimensional values, component properties on the Slice Component specification Used to define properties of a component (attribute, dimension etc) which are specific to its usage in a DSD. Component set Abstract class of things which reference one or more ComponentProperties Attribute property The class of components which represent attributes of observations in the cube, e.g. unit of measurement Attachable (abstract) Abstract superclass for everything that can have attributes and dimensions Component property (abstract) Abstract super-property of all properties representing dimensions, attributes or measures Data structure definition Defines the structure of a DataSet or slice Dimension property The class of components which represent the dimensions of the cube Coded property Superclass of all coded ComponentProperties Hierarchical Code List Represents a generalized hierarchy of concepts which can be used for coding. The hierarchy is defined by one or more roots together with a property which relates concepts in the hierarchy to thier child concept . The same concepts may be members of multiple hierarchies provided that different qb:parentChildProperty values are used for each hierarchy. Observation Group A, possibly arbitrary, group of observations. Observation A single observation in the cube, may have one or more associated measured values Slice key Denotes a subset of the component properties of a DataSet which are fixed in the corresponding slices order indicates a priority order for the components of sets with this structure, used to guide presentations - lower order numbers come before higher numbers, un-numbered components come last code list gives the code list associated with a CodedProperty observation group Indicates a group of observations. The domain of this property is left open so that a group may be attached to different resources and need not be restricted to a single DataSet structure indicates the structure to which this data set conforms component attachment Indicates the level at which the component property should be attached, this might an qb:DataSet, qb:Slice or qb:Observation, or a qb:MeasureProperty. slice key indicates a slice key which is used for slices in this dataset observation indicates a observation contained within this slice of the data set dimension An alternative to qb:componentProperty which makes explicit that the component is a dimension component indicates a ComponentProperty (i.e. attribute/dimension) expected on a DataSet, or a dimension fixed in a SliceKey slice structure indicates the sub-key corresponding to this slice component specification indicates a component specification which is included in the structure of the dataset measure An alternative to qb:componentProperty which makes explicit that the component is a measure measure dimension An alternative to qb:componentProperty which makes explicit that the component is a measure dimension component required Indicates whether a component property is required (true) or optional (false) in the context of a DSD. Only applicable to components correspond to an attribute. Defaults to false (optional). slice Indicates a subset of a DataSet defined by fixing a subset of the dimensional values parent-child property Specifies a property which relates a parent concept in the hierarchy to a child concept. attribute An alternative to qb:componentProperty which makes explicit that the component is a attribute Specifies a root of the hierarchy. A hierarchy may have multiple roots but must have at least one. data set indicates the data set of which this observation is a part concept gives the concept which is being measured or indicated by a ComponentProperty measure type Generic measure dimension, the value of this dimension indicates which measure (from the set of measures in the DSD) is being given by the obsValue (or other primary measure)
