The purpose of this page is to host a discussion about improvements to the ILC Track class. The discussion might expand to include related classes such as hits and vertices.
Some of our efforts on SiD tracking are now suffering from limitations imposed by the existing LCIO track classes. For example we have a tower of Babel problem: many of our colleagues have created their own private, incompatible, extensions to the publicly supported track, hit and vertex classes. New code, currently under development, will require further extensions. At the DESY ILC meeting several speakers from other detector concepts reported that they too required extensions.
