This section describes the data and algorithmic components that are REQUIRED for implementations of VRS.
Required External Data: All implementations will require access to sequences and sequence accessions. The Required External Data section provides guidance on the abstract functionality that is required in order to implement VRS.
Normalization: Expands Alleles to the maximal region of representational ambiguity.
Computed Identifiers: Generate globally unique identifiers based solely on the variation definition.
