Michael: I guess the advantage of Tika is that it can provide us today
with one single interface to import virtually any kind of file that
can contains text. Nothing is perfect but it seems it can resolve 80%
of our importing needs. And it can give us a formatted XML or XHTML
document that facilitates formatting. Someone may have turned it down
a few years ago, for legitimate reasons, but the fact remains that it
seems like a mature product today.
About PDF documents if they were not created with accessibility in
mind they can be a bitch to work with. I have run across this issue
before. Some people create them to be difficult to hack, on purpose,
to protect their copyright. This is another issue that users should be
aware of.
François.
