LSID

Introduction

A naming convention that would create a standard identifier for any biological entity (gene, protein, interaction, and so on). An LSID consists of five parts or fields, separated by colons:

1. Network Identifier (NID)
2. The root DNS name of the issuing authority
3. The namespace chosen by the issuing authority
4. The identifier unique in that namespace
5. An optional version id

Examples:

    lsid:ncbi.nlm.nih.gov:GenBank:T48601:2

The second version of an EST from GenBank.

    lsid:pdb.org:pdb:1AFT:1
