E-Print or E-Text?

Considering the golden future of Open Access (OA) eprint archives there are a lot of unanswered questions.

Which is the best data format for archiving articles?
(Most people believe: PDF)

Should repositories accept all sort of possible types of articles which are published also in print?

Possible types:
* author's text file given to the editors (before or after peer review or without peer review)
* author's text file with indication of printed pagination
* publisher's PDF
* publisher's PDF with additional materials (corrections, additions, abstract)
* author's text file with such additamenta
* scanned printed publication (images) without e-text
* scanned printed publication  (images) with OCR-text in one PDF (cf. "Paper Capture")
* scanned printed publication (images) and separate e-text (OCR'd or author's file)
* scanned printed publication with author's manuscript notes
and so on ...

Which is the best solution for each academic discipline?

If there is no permission to use publisher's PDF or there is no such PDF - should the author archive his text file or a scanned version of the printed text?

Are repositories accepting PDFs with text behind the image? See

(This seems the most simple solution, if one wants both image + e-text: good OCR software like ABBY Finereader can generate such PDFs.)

I suppose

is such a PDF.
