As you know, djvu format is an excellent and open format, but its fate is uncertain since it is overwhelmed by pdf, surely excellent, but closed and very difficult to manage.
Even if a small part of djvu features are used by mediawiki, djvu in a necessary tool for wikisource work.
Unluckily, there's no sufficient work about djvu, and I see that recently ABBYY discontinued the support of djvu format as output in its OCR engines. This is probably the cause of discontinuation of djvu files output bi Internet Archive.
Is it possible to encourage MediaWiki to devoid sufficient energies to save djvu format to its fate?
