ABSTRACT
The Taxonomy.dat file exceeds 100 megabytes (MB) in length. The Taxonomy.dat file is available for public download through anonymous ftp. ftp://ftp.ebi.ac.uk/pub/databases/taxonomy/ More information on the Taxonomy.dat file is found at https://www.ebi.ac.uk/msd-srv/docs/dbdoc/ref_taxonomy.html
Notice that the sample entry (above) provides an ID number for the entry organism, Chondromyces, and for its parent class. Since every organism and class has a parent, you can write a script that reconstructs the full phylogenetic lineage for any entry in Taxonomy.dat.
