atlas-data-v1.1.xsd 1.2 2006/04/21 (c) Copyright 2006 GeoWise Limited. See http://www.instantatlas.com/ for related information. This schema defines the data structure for XML files used in InstantAtlas reports. The root element for the data file. The data source for this data. This could be the data manager version or some other information. It is deliberately left free-form! End clients can use this any way they choose! A list of themes for an atlas. A choice between an 'in-line' definition for a theme or one held in an external file. A pointer to a file containing one "Theme" element. An individual indicator. This allows a quick lookup of the indicators in a theme without loading the external file. The ID of the theme. The name of the theme - this will be used in user interfaces. An individual theme with its own set of indicator children. An individual indicator. A summary of the numerical data held in an indicator. This should only be present (and will only be looked for by code) if the parent Indicator is marked as "numeric". The minimum numerical value held in an Indicator. The maximum numerical value held in an Indicator. The mean of the numerical values held in an Indicator. The standard deviation of the numerical values held in an Indicator. The median numerical value held in an Indicator. An individual indicator whose data is held in a separate file. The ID of the theme. The name of the theme - this will be used in user interfaces. The data type of an individual indicator. Note that 'rate' is just a synonym for 'numeric'. Attributes belonging to an indicator. The ID of the indicator. The name of the indicator which will be displayed in user interfaces. The type of data that is valid for this indicator - one of 'numeric' or 'categoric'. The precision (number of decimal places) for the data within this indicator. This is a presentation attribute - it does not constrain the actual data values but should be used by any presentation of the data (e.g. in a table). An individual geography type that can be used in this atlas - e.g. countries, wards or districts. Many atlases will only have one geography. The name of the geography - used in the user interface. A property that can be used for custom properties e.g. links, metadata etc. The value for a given indicator for a given geographical feature. The value for a given indicator for a given comparison feature. A filter that can be used against this feature. A feature can be "filterable" by a number of different filters. The ID of the individual geographical feature. This must be unique within a geography. The name of an individual geographical feature. This need not be unique within a geography, but is usually so. This should be used to populate lists, tables etc. in a user interface. Any link to metadata or further information about a feature. A list of all the features (points, lines or polygons) that belong to this geography. A list of any filters that can be applied to the data. This allows the user to thin out the data in the map. An individual feature (a point, a line or a polygon). An individual comparison feature. A comparison feature may or may not be present in any map. An individual filter that can be applied to the data. The unique ID of the filter. A filter ID only needs to be unique within a geography. The name of the filter. This should be used in GUIs, lists etc. The upper and lower limits of values associated with a geographical feature. The range for a given indicator for a given geographical feature. A set of data that is associated with an indicator but does not "stand-alone". Examples might be counts to compare with rates, etc. The precision (number of decimal places) for the data within this indicator. This is a presentation attribute - it does not constrain the actual data values but should be used by any presentation of the data (e.g. in a table).
