Leading journals reject Word 2007 files
Published: 14 Jun 2007 15:01 BST
Two leading academic journals have said they will not accept manuscripts written in Microsoft's Office 2007 suite.
The decision was made because the latest version of Word is no longer compatible with Mathematical Markup Language (MathML), the de facto standard for writing equations in text documents, according to recent notices posted on the websites of both Science and Nature journals. In Office 2007, Microsoft's own Office MathML (OMML) is used for equations.
"Because of changes Microsoft made in its recent Word release that are incompatible with our internal workflow, which was built around previous versions of the software, Science cannot, at present, accept any files in the new .docx format produced through Microsoft Word 2007, either for initial submission or for revision," Science journal stated on its site.
Likewise, Nature said it "currently cannot accept files saved in Microsoft Office 2007 formats [because] equations and special characters — for example, Greek letters — cannot be edited and are incompatible with Nature 's own editing and typesetting programs".
Murray Sargent, an Office software development engineer, noted on a Microsoft developer blog that Microsoft had looked at the need to maintain robust performance when it chose to integrate its OMML instead of MathML.
Sargent said: "Naturally there's been a lot of discussion as to why we even have OMML, since MathML is really good." However, he said, the main problem is that Word needs to allow users to include Word-oriented features, such as images, comments, revision markings and formatting into maths zones, but MathML is geared towards allowing only mathematical data in maths zones. Maths zones are areas in which users can input mathematical components and equations.
"A subsidiary consideration is the desire to have an XML [document] that corresponds closely to the internal [standard] format, aiding performance and offering readily achievable robustness," he said, adding that since both MathML and OMML are XML-based, they can be converted from one into the other. "So it seems you can have your cake and eat it too," Sargent said.
However, Science maintains that Word 2007 users should be aware that equations created with the default equation editor included in Microsoft Word 2007 and used in revisions will not be accepted by the academic journal, "even if the file is converted to a format compatible with earlier versions of Word".
Science said this is because "conversion will render equations as graphics and prevent electronic printing of equations and because the default equation editor packaged with Word 2007 — for reasons that, quite frankly, utterly baffle us — was not designed to be compatible with MathML".
Responding to the issues highlighted by Science and Nature, Sargent said in a separate blog posting that Word 2007's new mathematical facility is a huge improvement over previous approaches. "But anytime such big improvements occur, there can be, and evidently are, problems with upgrading," he said. "I think the trouble is well worth it in both user convenience, and the marvellous typographic quality."
Microsoft was unable to respond to queries by press time.
