Ruby implementation of openEHR

I had a presentation of current status of Ruby implementation project of the openEHR in "ICHCTH7":http://www.ineag.gr/ICICTH/ July 16, 2009. The presentation file is shown by "ODP":http://openehr.jp/attachments/download/17/icicth7.odp and "PDF":http://openehr.jp/attachments/download/16/icicth7.pdf.
This presentation method is "Takahashi method":http://en.wikipedia.org/wiki/Takahashi_method. I could impact European people with this method.
