$Id: glsGetData_response.xsd 2008-01-04 $ This XML Schema encodes the GLS GetData response. Copyright (c) 2008 OpenGIS, All Rights Reserved. Geospatial Data Attribute Set RFC 4646 language code of the human-readable text (e.g. "en-CA") The value of the 'Dataset/Attribute/Name' element is referenced by the 'aid' attribute of the 'Rowset/Row/V' element. The value for the 'aid' attribute must be a value present in the 'Dataset/Attribute/Name' element. One or more paragraphs of human-readable relevant text suitable for display in a pop-up window. Attribute descriptions. The order of these is determined by the order of the attributes listed in the request. One or more paragraphs of human-readable text describing the attribute and suitable for display in a pop-up window. Valid values. Name of the attribute field in the database. Data consists of the number of some observable elements present in the spatial features Datatype, as defined by XML schema. Length of the field, in characters. Domain name of the organization responsible for maintaining the attribute dataset. Name of the common key field found in the attribute dataset whose contents match those of the foreign key found in the spatial framework. These values populate the 'Rowset/Row/K' elements. Datatype, as defined by XML schema. Length of the field, in characters. Name of the attribute dataset. Normally the name of the dataset inside the RDBMS. Version number of the attribute dataset. The combination of DatasetDomain, DatasetName, and DatasetVersion must uniquely reference one spatial dataset. URL reference to a web-accessible resource which contains further information describing this object. Valid exception classes for this attribute. Valid null values. Text string representing a null value, found in the V elements of this attribute Spatial Framework to which the attributes apply. Domain name of the organization responsible for maintaining the spatial framework. Name of the common key field in the spatial framework dataset through which data can be joined. The values of this key populate the 'Rowset/Row/K' elements in the GetData response. Name of the spatial framework. Normally the name of the GIS dataset. Version number of the spatial framework. The combination of FrameworkDomain, FrameworkName and FrameworkVersion must uniquely reference one spatial framework. Spatial Key Identifies if there is at least one record in the Attribute dataset for every record in the Framework dataset. “true” indicates that this is the case. “false” indicates that some Keys in the Framework dataset cannot be found in the Attribute dataset. Identifies if the relationship between the Framework and the Attribute datasets are 1:1 or 1:many. “one” indicates that there is at most one record in the Attribute dataset for every key in the Framework dataset. “many” indicates that there may be more than one record in the Attribute dataset for every key in the Framework dataset. Data consists of measurements of some characteristic attributable to the spatial features Datatype, as defined by XML schema. Length of the field, in characters. Data consists of unique names for spatial features Valid nominal classes for this attribute. Valid (non-null) values. Text string found in the V elements of this attribute Datatype, as defined by XML schema. Length of the field, in characters. Ordered classifications data Valid ordinal classes for this attribute. Valid (non-null) values. Text string found in the V elements of this attribute Rank order of this value, from lowest = 1 to highest. Datatype, as defined by XML schema. Length of the field, in characters. Human-readable name of the organization responsible for maintaining this object. Human-readable short description suitable to display on a pick list, legend, and/or on mouseover. Date of publication. Values that apply to this spatial key identified for this row, in the same sequence as the attribute descriptions above. Rowset type defines a section for a dataset. Rowset can be presented more than once. However the efficient use of Rowset will be once per GetData response Dataset Rows Unit of Measure Value of a specified attribute for the geospatial identifier for this Row. When this value is null (indicated with the null attribute) an identification of the reason may be included in the content of this element. Attribute identifier, namely the corresponding AttributeName Boolean value, when present and "true" indicates that this particular value is missing for some reason, and the contents of the element must be processed accordingly.
