OWL RELEASE NOTES
  1.O Current contents

  Release 31.1 of OWL contains 279,796 entries. The relatively small size
  of the database, compared with the sum of the entries in its primary
  sources, reflects the strict nature of the redundancy criteria used
  in its construction: all identical and trivially-different sequences
  (i.e. those having a single amino acid change) are removed. 

  SWISS-PROT is currently the highest priority source, and all others
  are compared against it. The sudden drop in contribution from NRL-3D 
  marks the point at which we included this source in the redundancy
  comparison (this was necessary as NRL_3D was growing rapidly and
  was thus fast compromising the non-redundant status of OWL).

  OWL is released in major and minor versions: minor releases reflect
  updates of the lower priority sources; major releases denote updates
  of SWISS-PROT. A major or minor version of OWL is release every 6-8
  weeks. The length of time between releases is a function of the 
  method used to index the database: the indices generated are large,
  but the payoff is achieved with the high speed of database queries.


  2.0 Database growth 

  The database is growing with a doubling rate of around 18 months. The
