In order to achieve joined-up government objectives the Office of the eEnvoy has established the e-Government Interoperability Framework (e-GIF). IT vendors, including those in GIS must demonstrate their ability to comply with approved technical standards and Government commitments in order to work with UK Government agencies and departments.
The OGC specifications are now widely regarded as the de jure geospatial standards for GIS. This would concur with Version 4.1 of the e-Government Interoperability Framework Part Two (Technical Policies and Specifications) document, which states in Table 9 (Specifications for Business Purposes) for GIS and GIS data users the OGC GML standard has been approved and adopted as of 31 October 2002.
Cadcorp users have the ability to parse, display, and export Geography Mark-up Language (GML) via desktop and Internet mechanisms as standard. This includes OS MasterMap (independent and topological) files and the OS MasterMap Address Layer.
Cadcorp monitor the UK GOVTALK ) web site closely.
