Thank you, Fabrizio…

Do you want only “handwritten” SignWriting documents in vertical columns? I had gotten the impression that your project wanted only “writing by hand” kind of documents?

But then you mention in any digital format….so could that be computer written texts as well?

I have a lot of handwritten documents from our past, in my garage (can you believe?), that are sitting in notebooks…mostly written with ink pens in stick figures from the early 1980’s for the SignWriter Newspaper project. None of it is computer written because we did not have computer programs at that time - so it is all written by hand with ink pens and most of it looks better than the average handwriting because the purpose of most of the documents was to be published as articles in the SignWriter Newspaper. Most of it is stick figures written receptively and horizontally from left to right -

But I also have other documents of individuals around the world writing by hand too…but not all of it is in vertical columns - some in stick figures and some not -

So my point is, do you want to see the enormous variation of handwritten documents, from 1974-today? or do you want to see computer-written texts too, like the ASL Wikipedia? Steve mentioned that it a previous message and there are some cool things happening with the ASL Wkipedia project and character recognition for that project would indeed be wonderful -

Regarding the ASL Wikipedia project….

Steve is in the process of moving our ASL Wikipedia site from a test area on Wikimedia Labs to the Wikimedia Incubator server. The goal of course is to someday become an “official” Wikipedia, but there is more software development to complete before that can happen. We are excited to be moving over to the Incubator web site. At the moment, the site can be best viewed if you use Chrome or Safari web browsers….Below is a link to a page that lists the titles of some of the documents that have been moved to the Incubator…and as you can see the entire site, including the Menus and the Titles for the articles, are written in ASL. In time, there will be a way to toggle back and forth between languages so the Menus can change languages later, if you cannot read a Menu item in ASL...

Using Chrome or Safari, go to Titles and click on a title in SignWriting to view an article in ASL:
http://incubator.wikimedia.org/wiki/Special:PrefixIndex/Wp/ase/

So give me some guidelines - should I scan in pages of handwritten documents from the 1980s? Or do you want more modern documents the way the world is writing right now? and is it only hand-written documents that you want?

Val ;-)

I want you to know that I have not forgotten you…but have been waiting for a quiet moment to be able to concentrate and to provide you with all the feedback and materials you need…So you are in my thoughts, and a real answer is coming -  All is well here… Just have to take one step at a time… I look forward to more communication this weekend - Val ;-)
