This is an unofficial library which aims to provide a unified data structures for handling NCBI data. The goal is to model NCBI spec's as close as possible to allow for both submission and parsing.
Currently, the only specification that's been implemented is the NCBI ASN.1 biological sequence data format, and seems to be the first non-official, publicly available implementation of this spec.
That work is currently being exended for XML exports of Entrez gene descriptions, as described here.
