The Textual Work of August Walla, mentally disabled artist

[Alin_J]

That sounds very promising, thank you! 

I would also need some advice on how to prepare the data. Is capitalization important? Should line breaks be included? Should voids in the lines (due to the structure of the painting) be marked? Which kind of metadata should be provided? That's what I would think of, but there's probably more...

I think that the transliteration should be kept to keep as much of the original character layout as possible. So, yes capitalization is important. Regarding spaces either certain, or uncertain (if the spacing is dubious) would suffice for me. But line breaks are important. If drawings are inside the text It would also help to know location markers for them, to be able to determine what text they are near, and to clearly separate them from the text itself.
