Examples

The first thousand CDS records from the latest release associated with Taxon:9606 are returned in text format using the following URL: http://www.ebi.ac.uk/ena/data/view/Taxon:9606&result=coding_release&offset=1&length=1000&limit=1000&display=txt

The following thousand CDS records from the latest release can be returned using the following URL: http://www.ebi.ac.uk/ena/data/view/Taxon:9606&result=coding_release&offset=1001&length=1000&limit=1000&display=txt

By default only the records directly associated with the <taxon identifier> are returned. All records associated with the taxon and any of its subspecies or strains can be returned by setting the subtree option to true.
