PDF standards update from Ottawa
Martin Bailey at 14:35 GMT on 6 December 2010
Several of the ISO PDF standards committees met in Ottawa, Canada last week; this is a quick catch up on the key points from each.
PDF/A – Archiving
The PDF/A committee reviewed all comments to the final ballot on ISO 19005-2 (PDF/A-2) and ratified the standard for publication. All of the meeting’s agreements will now get rolled into the text, which will then be forwarded to ISO Central Secretariat for final processing. It’s always hard to predict how long that will take, but I’m expecting publication some time in Q1 2011.
We also made some good progress on PDF/A-3, which differs from PDF/A-2 in only one respect: that any file can be embedded within it for a variety of reasons. This can be used to attach source documents (e.g. the Word file you made the PDF/A file from), measurement data used to create a graph, alternative representations etc. The embedded files don’t need to follow the same rules for being meaningfully readable at some distant point in the future as the main PDF/A content itself.
PDF/E – Engineering
The PDF/E committee agreed to start work on PDF/E-2 to enable the archiving of engineering documents. They are running into one of the most common challenges in standards work, however, in that there is widespread demand for the standard, but finding experts willing to invest time in developing it is proving difficult. Volunteers would be welcome!
PDF/UA – Universal Accessibility
The PDF/UA-1 standard is currently in what may be its final ballot before ratification, so wasn’t discussed in Ottawa. If all goes according to plan, that will be published in the second half of 2011, and may even become one leg of the next version of Section 508.
The committee started the work to develop a PDF/UA-2 standard, based on ISO 32000-2 (the next version of the ISO PDF standard itself, see below). That standard already includes a lot of work on accessibility that’s been done in preparation for its use in this way.
PDF itself
All of the comments to the last committee draft (CD) ballot on the next version of PDF (ISO 32000-2) were reviewed and resolved. Several more substantial proposals regarding topics such as what a PDF reader must do and the relationships between the various subset standards were discussed.
The committee decided that the standard is not yet solid enough to go to a ‘Draft International Standard’ (DIS) ballot, which could have been the final stage of the process. Instead it will be updated with the agreements from this meeting and then issued for another CD ballot. The results of that will be discussed in May next year, and may lead to a DIS ballot after then. If so then 32000-2 might be ratified at the end of 2011, and published in early 2012.
That’s it from the great wet North (for some reason the UK and Canada appeared to swap their early Winter weather last week).
