LCG Application Area projects

There are many frameworks in High Energy Physics (HEP) which need the geometrical description of detectors. The geometry description very often comes in the form of source code the frameworks and applications are implemented (FORTRAN,C,C++,Java,Python) or is kept in various proprietary formats (formatted text, databases of each sort).

If a geometry description is encoded in one of these forms, it is very hard or even impossible to share the whole or some part of the description by two or more frameworks/applications to save the user's time, space and effort. In addition when encoded in the implementation language, it makes the development cycle and testing of the geometry description even longer due to the fact that one has to rebuild the library or application each time the geometry has been modified.

The extensible mark-up language (XML) comes very handy in this context because it gives the framework/application developers and users the way they can design the geometry description independently from the particular framework/application, thus increase designer's productivity, make maintenance easier and provide the possibility to build a set independent tools like editors, import/export components, visualisation tools etc.
