[nfbcs] accessible design software

Tue Jul 28 19:21:23 UTC 2015

Hello Marvin,

I would like to echo what Jim said and that it is important to understand what these UML and State Chart diagrams look like and why they are used. In my Software design class I worked with a group to develop these diagrams for our team project although I did things a little different. As Doug said I did not see a link in Gregs post but here is the system I used which will allow you to use XML to create State Charts and other diagrams. There are a few different tools you might need to download and use to export the XML as a visual model but if your professor needs you to demonstrate your understanding of what is going on in the state charts this was completely acceptable by my professor. Honestly if you can write the diagram in XML and represent the states of a program it is pretty clear you understand what the visual model is doing as well. Here is the link to the tool by Apache I am speaking about and I also attached a small example for you to see...

Go Devils!

If the software has example files that are ascii in nature then you have a chance.  You may have to study those diagrams enough so you understand what all those symbols mean if the software isn't otherwise accesible in terms of input and output interfaces.  If you do end up having to do that and use a text editor to create your diagrams, try to segment the diagrams so for example you can use the pieces you make to build other diagrams with them.  Structured programming and structured diagram building are alike in this respect.  If you already are fluent in latex that's another and different possible avenue for you to investigate.  If you don't have a knowledge of latex, probably now isn't a good time to learn.  I think I remember reading that graphvis could do some of this stuff but that was a while ago and I never had exposure to the package.  Also, if you do a google search for that package put a tilde in front of it ~graphvis since I may not have spelled it completely correctly.
