Germany has just made the standard Open Document Format (ODF) mandatory

This is a most excellent place for technology news and articles.
More than that, it's standardization made MS panic and pseudo-standardize their OOXML (.docx & co.) a year later, since some govt wanted to switch to ODF back in 2007, instead of relying on some proprietary format. The pseudo, because most of the format is proprietary extensions (and only the strict variant is standard-conformant, which MS doesn't set as default), which made the standardization a ...unusual process.
Btw, usually, there's only one standard format for a specific usecase.
