IBM, Microsoft and Sun have responded positively to the Telematics between Administrations Committee (TAC) Open Document Format Recommendations. On 25 May 2004, members of the TAC endorsed several recommendations that promote the use of open document formats by the public sector while encouraging major players in the field of document processing to involve official standard organisations in their work on document formats. Their positive responses represent a significant step on the way to establishing fully interoperable and seamlessly connected public administrations throughout Europe and enable seamless and transparent transactions between EU public administrations, citizens and businesses.
