NAME

spt2centroid.pl - Munge an SPT export into a WHOIS++ centroid

SYNOPSIS

  spt2centroid.pl <spt.txt >centroid.txt

DESCRIPTION

The spt2centroid.pl program takes a bulk export produced by the Scout Portal Toolkit (SPT) software, and uses it to generate an RFC 1913 style WHOIS++ ``centroid''. Centroids are the WHOIS++ forward knowledge summary mechanism, and are supported by default in the ROADS software's cross-searching subsystem.

Note that the centroids produced by this program are based on the DUBLINCORESIMPLE ROADS template type, which encapsulates unqualified Dublin Core elements.

EXAMPLE

  $ tail -1 bar.spt
  Cities of the Red Night         Burroughs is an awe-inspiring
  poetic magician.  I believe Cities of the Red Night is his
  masterpiece - Christopher Isherwood
  http://www.hyperreal.com/wsb/                                
            1981   1981     1981    1981    0

(SPT records use the tab character as a delimiter - but the above has been word wrapped for readability)

  $ tail -1 bar.spt | spt2centroid.pl
