5. LINK DOWNLOAD SERVICE OPERATION

The Link Download Service operation allows the declaration of the availability of a Download Service compliant with this Regulation, for the download of resources through the Member State’s Download Service while maintaining the resources at the owner location.

5.1. Link Download Service request

5.1.1. Link Download Service request parameter

The Link Download Service request parameter shall provide all information about the Public Authority’s or Third Party’s Download Service compliant with this Regulation, enabling the Member State Download Service to provide access to Spatial Data Sets and, where practicable, to Spatial Objects from the Public Authority’s or Third Party’s Download Service.

PART B

Direct Access Download Operations

6. LIST OF OPERATIONS

Where the Download Service gives direct access to spatial data sets, it shall provide, in addition to the operations listed in Table 1, the operations listed in Table 2 of this Annex.

Table 2

Operation Role Get Spatial Object This operation allows the retrieval of Spatial Objects based upon a query. Describe Spatial Object Type This operation returns the description of the specified Spatial Objects types.

The request and response parameters of each operation complete the description of each operation and form an integral part of the Download Service’s technical specifications.

— Query.

7.1.1. Language parameter

The Language parameter shall indicate the natural language requested for the Spatial Objects.

7.1.2. Spatial Data Set Identifier parameter

The Spatial Data Set Identifier parameter shall contain the Unique Resource Identifier of the required Spatial Data Set. Where the parameter is not provided, it shall be assumed that all available Spatial Data Sets have been selected.

7.1.3. Coordinate Reference System parameter

The Coordinate Reference System parameter shall contain one of the Coordinate Reference Systems included in the list of Coordinate Reference Systems set out in Regulation (EU) No 1089/2010.
