A GI number (for GenInfo Identifier, sometimes written in lower case, gi) is a simple series of digits that are assigned consecutively to each sequence record processed by NCBI. The GI number bears no resemblance to the Version number of the sequence record. Each time a sequence record is changed, it is assigned a new GI number.
ncbigi
Local identifiers in GenInfo Identifier should match this
regular expression:
^\d+$
Compact URIs (CURIEs) constructed from GenInfo Identifier should match
this regular expression:
^ncbigi:\d+$
The metaregistry provides mappings between the Bioregistry and other registries. There are
4 mappings to external registries for ncbigi
with
4 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE
ncbigi:568815597
is used to demonstrate the provides available for
ncbigi
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
