Dear libtiff-Developers,

Because we need some validation and repair tools for TIFFs by reasons

I'll take a look at your stuff over the next days or weeks and give it a try on a number of TIFFs I have laying around here (mostly found on h ttp://bitsavers.org mirrors).

I believe the best opportunity to go forward with TIFFs is to deal with inaccuracies and to try to "cure" inaccuracies where possible, e.g. date/time formats and their variations. You can devise rules to detect and convert almost any strange date/time format to something meaningful.

Still, trying to fix and convert TIFFs to follow a baseline rule makes sense when it comes to long time preservation. I know it is (much more) important for definitely binary image data from the past.

Cheers
Jürgen
