.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is an implementation of Bio::DB::Taxonomy which stores and accesses the
Silva taxonomy. Internally, Bio::DB::Taxonomy::silva keeps the taxonomy
into memory by using Bio::DB::Taxonomy::list. As a consequence, note that the
IDs assigned to the taxonomy nodes, e.g. sv72, are arbitrary, contrary to the
pre-defined IDs that \s-1NCBI\s0 assigns to taxons. Note also that no rank names or
common names are assigned to the taxa of Bio::DB::Taxonomy::silva.
.PP
The latest Silva taxonomy (2011) contains about 126,000 taxa and occupies 
about 124 \s-1MB\s0 of memory once parsed into a Bio::DB::Taxonomy::silva object.
Obviously, it can take a little while to load.
.PP
The taxonomy file SSURef_108_tax_silva_trunc.fasta that this module uses is
available from <http://www.arb\-silva.de/no_cache/download/archive/release_108/Exports/>.
