Re: units in MathML

Hi folks,

I believe that, at least for now, properly capturing the semantics of units definitions is outside the scope of MathML. I'm making use of MathML in an academic/commerical effort to encode cellular models in XML, producing a language called CellML ( http://www.cellml.org/ ). An important part of this language is the inclusion of units, making the model descriptions robust and portable.

I've put a PDF summarising the current status of our work on a units framework on an FTP server here: ftp://ftp.esc.auckland.ac.nz/pub/hedley/cellml/units.pdf . Those interested are welcome to look at this, and steal ideas from it. Note that this is not the same as the version currently on the CellML website -- it is part of the next draft of our specification. To get an idea of how variables are defined, and how MathML is embedded in CellML, I'd recommend having a look at Figure 9 on Page 11.

I'd welcome any feedback on this. Please send it to me personally, as I only loiter on this list infrequently.
