0210 Data Stores

Both DataSets and DataStores are types of Asset that represent a collection of data. The DataStore is a physical store, whereas the DataSet is dynamically constructed on request. This model introduces the DataStore and the relationship that shows how DataSets are constructed from them.

UML

DataStore entity

The DataStore entity describes a physical digital resource that supplies data. The deployedImplementationType attribute describes the class of technology that is used in its implementation. Values for the deployedImplementationType attribute can be managed for consistency in a deployed implementation type valid value set.

DataContentForDataSet relationship

The DataContentForDataSet relationship defines how data is supplied to a DataSet from a particular digital resources. The DataSet entity includes a property called formula. This describes the logic that is used to populate the data set. The formula can include placeholders. These placeholders are defined by the queryId properties in the linked DataContentForDataSet relationships. The associated query property describes how the data from the linked dataContent resource is selected.

DataStoreEncoding classification

The DataStoreEncoding classification provides the ability to store details of the data stores physical characteristics.

DataScope classification

The DataScope classification identifies the scope of the data stored in the digital-resource(s) represented by the entity it is attached to. This classification can be attached to any Referenceable, but it is typically associated with assets such as DataStores and DataSets. The attributes of this classification identify the scope of the data in space and time.

  • minLongitude - if the data is bound by an area, this is the longitude for bottom-left corner of the bounding box (BBOX) for the area covered by the data.
  • minLatitude - if the data is bound by an area, this is the latitude for the bottom-left corner of the bounding box (BBOX) for the area covered by the data.
  • maxLongitude - if the data is bound by an area, this is the longitude for top-right corner of the bounding box (BBOX) for the area covered by the data.
  • maxLatitude - if the data is bound by an area, this is the latitude for top-right corner of the bounding box (BBOX) for the area covered by the data.
  • minHeight - if the height above ground is relevant, this is the lowest height that the data covers.
  • maxHeight - if the height above ground is relevant, this is the highest height that the data covers.
  • startTime - if the data is bound by time, this is the start time.
  • endTime - if the data is bound by time, this is the end time.
  • additionalProperties - to support other properties that identify the scope of the data represented by this element.
