Yes, Lets call it the Electronic Data Interchange Format :)


Seriously I would like to help in this effort.  I am currently working on a
open source eda tool suite based
on ip-xact and extending it to support symbol graphics is a natural
extension.

The data model exists between EDA suites, fabs and part vendors.<br>
