NAME

Bio::DB::MeSH - Term retrieval from a Web MeSH database

SYNOPSIS

my $mesh = Bio::DB::MeSH->new();
my $term = $mesh->get_exact_term('Butter');
print $term->description;

DESCRIPTION

This class retrieves a term from the Medical Subject Headings database by the National Library of Medicine of USA. See http://www.nlm.nih.gov/mesh/meshhome.html. It uses the latest data available (updates happen on weekdays). If it fails, an archive cgi scripts accessing older data from previous year is used.

This class implements Bio::SimpleAnalysisI and wraps its methods under get_exact_term.

By default, web access uses WWW::Mechanize, but in its absence falls back to bioperl module Bio::WebAgent which is a subclass of LWP::UserAgent.
