Implementation Guide

This section describes the data and algorithmic components that are REQUIRED for the implementation of Cat-VRS. This page will be updated as work on the reference implementation proceeds. Please check back later for more information!

• Read the Introduction and How Cat-VRS Works to understand the specification.

• Review the Data Model and associated examples. CategoricalVariants are constructed using Constraints, and Recipes are standard types of categorical variants.

• Validate your constructed CategoricalVariants using the Python reference implementation, Cat-VRS-Python.

The VICC Variation Normalizer, VRS-Python, and SeqRepo are useful services for generating VRS Allele and Location objects, both of which are required for implementing the Defining Allele Constraint and Defining Location Constraint.
