Standard/recommended formats for network information

[Bruno Quoitin <bqu () info ucl ac be>]

Looking for advice.

I would like to know if there are standard or widely used file formats 
to represent the following information:

   * intradomain topology (including IGP costs, bandwidths, delays, SRLG)
   * BGP peerings
   * traffic matrices

Thanks in advance

Bruno
