As demonstrated by this thread, it's entirely possible to modify such files, even if the currently-easy ways to do that involve a trip through a completely different representation. I find it astonishing that anyone would seriously call any documented file format read-only. (If PDF/A isn't documented, then IMO it's not suitable for archival under any circumstances. But this thread makes it sound as though it's documented.) /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ----- I wasn't intending to make an existential claim. I was making an observation that, yes, was based on experience with a particular tool. And now I've found how to extend that tool to remove that limitation, thank you Guy :->. PDF/A still has properties that are specific to a community-of-use. Evidently Al thinks those properties are detrimental to the intent of Bitsavers? I wasn't previously aware of that issue; perhaps others here were also unaware? ----- paul
