The work on the TI/A project, to define an archive-friendly version of TIFF analogous to PDF/A, is still going, even though hardly any of it is publicly visible. Marisa Pfister’s leaving the project, along with her position at the University of Basel, was unfortunate, but others are continuing a detailed analysis of TIFF files used at various archives. This will help them to learn what features and tags are used.
The target of March 1, 2016, for a submission to ISO has been crossed out, and nothing has replaced it, but we can still hope it will happen.
Mad File Format Science 
I plan to talk about some of my TIFF work at Digital Preservation in Milwaukee in November. I’ll post slides and notes after the talk.
