Unfortunately, that's not the case with TIFF given the variety of variants and incompatible implementations :(. Consider the following... 100 years from now someone comes across a storage device containing two documents - one in PDF/A and one in TIFF. There are no current "software" products that can read either format, and so one must be written from specification. ASSUMING that the specifications/standard documents are available - which would be easier to implement from scratch WITH NO REFERENCE IMPLEMENTATION. THAT'S the overridding concept by which the PDF/A committee (of which I am a member) were striving for during our development of the spec. (not the TIFF part, but the general concept). And for anyone that things that 100 years is a LONG TIME - that's NOTHING compared to the legal requires for the US Gov't and Nuclear Regulatory folks.
