\page med-file Notes on the MED file format

\section med-file-intro Introduction

The MED file format is a specialization of the HDF5 standard, and existed well before
MEDCoupling. Take a look at the 
<a class="el" href="http://www.hdfgroup.org/HDF5/">HDF5 Group website</a> for more details on HDF5 itself.
It focuses on (potentially) big amount of data, and the design philosophy was to facilitate a
parallel usage.

The official documentation of the MED-file format is available on-line (in French) in 
your SALOME installation at:

\code{.sh}
${MEDFILE_ROOT_DIR}/share/doc/html/index.html 
\endcode

Remember that the term "MED-file" denotes both:
- a file format on disk (I/O)
- a comprehensive low level C library to read/write MED files (now with a Python wrapping)
and authored by Eric FAYOLLE  (EdF R&D).

\section med-file-struct What does it look like?

The picture below shows an UML-like diagram of the MED file format. 
We see for example that the mesh name is the unique key linking a \ref fields "field" 
to its supporting \ref meshes "mesh".
