Re: [Wikisource-l] Proofread extension "extraction" of OCR text in Djvu

I'm forwarding this message by George Orwell III on en-ws [1]. I think it
is extremely important as it offers an insight about what is wrong with
Djvu handling on Wikisource.

"We/you are losing the X-min, Y-min, X-Max & Y-max (mapping coordinates)
because the original PHP contributing a-hole for the DjVu routine on our
servers never bothered to finish the part where the internal DjVu text
layer is converted to a (coordinate rich) XML file using the existing
DjVuLibre software package because, at the time, the software had issues.

"That faulty DjVuLibre version was the equivalent of 4,317 versions ago and
the issue has been long fixed now EXCEPT that the .DTD file needed to base
the plain-text to XML conversion on still has the wrong 'folder path' on
local DjVuLibre installs (if this is true on server installs as well, I
cannot say for sure). Once I copied the folder to the [wrong] folder path,
I was able to generate the XMLs all day long. These XMLs are just like the
ones IA generates during their process (in addition to the XML that AABBY
generates for them).

"So its not that we as a community decided not to follow through with
(coordinate rich) XML generation but got stuck with the plain-text dump
workaround due to a DjVuLibre problem that no longer exists. Plus, the guy
who created the beginnings of this fabulous disaster was like tick with an
attention span deficit and moved on to conjuring up some other blasted
thing or another instead of following up on his own workaround & finish the
XML coding portion once DjVuLibre glitch was fixed. -- 15:16, 15 July 2013

I'm not sure his attitude will encourage people to work with him to his
specifications.

Re: [Wikisource-l] Proofread extension "extraction" of OCR text in Djvu [In reply to]

I had to moderate my response out of the belief that I would be banned from yet another wiki list by some tyrant.

By the way Kernal Dev didn't state this, one Intel developer named Sarah Sharp stated it.

But those against frank speech have to make it extreme in an effort to once again silence opposition instead of embracing this sort of speech as the only thing to drive the wagon.

Yeah, Linus is kind of an asshole too. I don't see that as something to

Re: [Wikisource-l] Proofread extension "extraction" of OCR text in Djvu [In reply to]

More on the great Sarah Sharp fiasco :)

I had to moderate my response out of the belief that I would be banned from yet another wiki list by some tyrant.

By the way Kernal Dev didn't state this, one Intel developer named Sarah Sharp stated it.

But those against frank speech have to make it extreme in an effort to once again silence opposition instead of embracing this sort of speech as the only thing to drive the wagon.
