A little while back I gave Peter Murray-Rust a
hard time for daring to suggest that OOXML might be acceptable for archiving purposes.
Here's his
response to that lambasting:
My point is that - at present - we have few alternatives. Authors use Word or LaTeX. We can try to change them - and Peter Sefton (and we) are trying to do this with the ICE system. But realistically we aren’t going to change them any time soon.
My point was that if the authors deposit Word we can do something with it which we cannot do anything with PDF. It may be horrible, but it’s less horrible than PDF. And it exists.
