This section describes the data and algorithmic components that are REQUIRED conventions for implementations of VRS.
- :ref:`required-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.
- :ref:`normalization`: Expands Alleles to the maximal region of representational ambiguity.
- :ref:`computed-identifiers`: Generate globally unique identifiers based solely on the variation definition.
