The Challenges of Implementing e-Government Interoperability in Thailand: Case of Official Electronic Correspondence Letters Exchange across Government Departments

In November 2006, Thai Government announced Thailand electronic government interoperability framework (TH e-GIF) as a collection of technical standards, methodologies, guidelines and policies to enable electronic data exchange across government agencies. The first challenging project was to implement the semantic interoperability for exchanging official electronic letters across 29 government agencies using 15 heterogeneous software systems developed by different vendors. To achieve the project goal, a holistic approach was designed in which many policy-makers and practitioners had to involve in collaborative activities. This chapter explores the approach in details. It includes the process of data harmonization, modeling and standardizations using a number of UN/CEFACT specifications, UMM, CCTS and XML NDR, and other international standards. From this project the first national XML schema standard was produced. This chapter also introduces a methodology of extending the interoperability to legacy systems based on web services technology. Finally, it describes risk managements with the key success factors for the electronic interoperability development in Thailand.
