ISO creates new standard around PDF format to aid preservation

The International Standardisation Organisation has announced the creation of ISO ISO 19005-1:2005, which standardises the format of PDF documents. PDF (Portable Document Format) is similar to the earlier PostScript (PS) format, both are from Adobe.

I guess the real question is whether any patent-holders are now going to crawl out from under their rocks and demand royalties. Adobe certainly appears to have done the right thing and granted liberal patent licences, all credit to them.
