Data Access Technical Panel - DATP

The Data Access Technical Panel addresses the technical and organisational aspects of the provision of data products and systems. It is concerned with the design of implementations within distributed, networked, computing systems that support the specifications defined in the DSTP and SITP. Those aspects of the technology relating to an underlying infrastructure within which services operate are also addressed in the Data Access Technical Panel. The support for common, networked, computing systems requires the specification of common network facilities. The specification of common data products requires the specification of product specifications that include the semantic information defined in the information viewpoint and the interfaces defined in the computational viewpoint.

A data product consists of a content model of the information components defined in the Data Structures Technical Panel together with an encoding or representation in a database. A data product also includes a set of capture criteria used to create data that adheres to the content model. While DGIWG does not create data products, it is responsible for the tools used to create data products that share common content models and encodings. Shared data products are established by separate agreements between DGIWG nations. The DATP provides the specifications needed to support the production of data and the implementation of systems within distributed, networked, computing environments. This work includes establishing testing and compliance procedures and "test data" to test data and interfaces defined in accordance with the work of the Data Structures and Services and Interfaces Technical Panels. Co-production of specific data series, such as the MGCP co-production, is done via multi-lateral co-production agreements between nations, where specific commitments can be made for mutual production, and thus it is outside the scope of DGIWG. DGIWG provides specifications and services which support such activities.

The responsibilities of the DAPT are to develop standards and specifications for data access to geographic information by supporting data production under co-production agreements,

• by providing interfaces to networks and other dissemination means; and
• by providing compliance testing mechanisms.

The DSTP is chaired by the DEU (Bundeswehr Geoinformation Office)
