<ext-link>
External Link
Link to an external file or resource.
Remarks
Use the standard XLink attributes to provide a live link to the external
source.
The @ext-link-type attribute can be used
to give an indication of the type of resource to which the external link points. While
this Tag Set does not constrain the values of this attribute, and ordinary text is
acceptable, the suggested values include:
ec | Enzyme nomenclature. See http://www.chem.qmw.ac.uk/iubmb/enzyme/ |
---|---|
gen | GenBank identifier |
genpept | Translated protein-encoding sequence database |
highwire | HighWire Press intrajournal |
pdb | Protein data bank. See http://www.rcsb.org/pdb/ |

pir | Protein Information Resource. See http://pir.georgetown.edu |
pirdb | Protein Information Resource. See http://pir.georgetown.edu |
pmcid | PubMed Central identifier |
pmid | PubMed identifier |
sprot | Swiss-Prot. See http://www.ebi.ac.uk/swissprot/ |

... <p>In the mid-1990s, the GenBank database became part of the International Nucleotide Sequence Database Collaboration with the EMBL database (<ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.ebi.ac.uk/">European Bioinformatics Institute</ext-link>, Hinxton, United Kingdom) and the Genome Sequence Database (GSDB; LANL, Los Alamos, NM). Subsequently, the GSDB was removed from the Collaboration (by the National Center for Genome Resources, Santa Fe, NM), and <ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.ddbj.nig.ac.jp/">DDBJ</ext-link> (Mishima, Japan) joined the group. ...</p> ...
