OWL is a non-redundant composite of 4 publicly-available primary
sources: SWISS-PROT, PIR (1-3), GenBank (translation) and NRL-3D
. SWISS-PROT is the highest priority source, all others being
compared against it to eliminate identical and trivially-different
sequences. The strict redundancy criteria render OWL relatively
"small" and hence efficient in similarity searches. References.
