Re: Evaluating Content MathML

Hello again,

First of all, thanks for all the answers. I will have a look at the 
software proposed by you, especially CellML looks promising.

Just to make it clear, here is what I am doing at the moment.

I am working on my Bachelors Thesis on storing characteristics 
(mathematical formulas), containing several parameters as variables, in 
an ontology. To instantiate the variable the parameters (real-values) 
are extracted from different concepts in the ontology.

I decided to encode the characteristics via MathML and to store them as 
XMLLiterals which are to be found as datatype properties in the ontology.

The project I am working with uses a Java written GUI that enables the 
user to instantiate the ontology without writing any OWL but with using 
drag´n drop and wysiwyg mechanisms.

One of my tasks is to implement a feature which enables the user to type 
in formulas (e.g (x + 5*y) * 4^2) without using MathML. These formulas 
should be encoded in MathML and they should be stored in the ontology. 
On the other hand the program has to be able to instantiate the 
variables of the given formulas and eventually calculate and return the 
result.

My task is not to write a MathML parser but to implement an exisiting 
one. Therefore my plan was not to use JDOM or another XML Library but 
maybe I was a bit to optimistic about the amount of my workload :-)

Thanks for your help,

Roman
