In the wake of the ISO rejecting Microsoft's OOXML document format as an international standard, Microsoft has launched its Document Interoperability Initiative pledging to work with industry to ensure its document formats remain interchangeable with industry standards.

Last year, when I was socializing the idea of creating the OASIS ODF Interoperability and Conformance TC, I gave a presentation I called "ODF Interoperability: The Price of Success". The observation was that standards that fail never need to deal with interoperability.

The British Standards Institution (BSI) has always been one of those iconic central points of reference in British life – a kind of Big Ben for standards. But it's a little hard to square that image – perhaps hopelessly outdated – with the BSI's recent decision to vote in favour of Microsoft's OOXML document standard.

On Friday FSFE sent a letter to the European Commission to support Open Standards and interoperability. In the drawn-out battle to retain at least a weak recommendation for Open Standards in the revised European Interoperability Framework, FSFE has countered a leaked letter by the lobby group Business Software Alliance with its own thorough analysis of the relation between standards and patents.

The Business Software Alliance (BSA) is pressuring the European Commission to remove the last vestiges of support for Open Standards from the latest version of the EU's interoperability recommendations, the European Interoperability Framework. FSFE has obtained a copy of a letter sent to the Commission by the BSA last week.

n a policy document specifically timed for release this afternoon, Microsoft's general managers for interoperability, Tom Robertson and Jean Paoli, make a play for ownership of the standards issue facing users of competing document formats, by saying the company would support ratification of its own Open XML format along with OpenDocument Format (ODF) as ISO standards, if and only if doing so woul

Last year's explanation of why interoperability simply harms standards

The final version of the important Digital Agenda for Europe has been leaked – and shows that the European Commission has betrayed open standards. Where an earlier draft had an entire section headed “Open Standards and Interoperability”, the latest version only uses the word “open” once in the corresponding section “Interoperability and standards.”

The European Interoperability Framework is just one battle among many. Besides the topic of interoperability in the public sector, there’s the task of reforming standardisation systems so that they produce Open Standards, and educating policy makers about the importance of the issue.
