 # Extending BioSamples' records
 The Python script ``biosamples-externalReferences.py`` defines a class BiosamplesRecord for managing biosample records. This class is designed to interact with the BioSamples database, allowing operations like fetching, updating, and extending biosample records.
 The script takes in a dictionary of BioSamples' accessions and their associated external references, and expands the former with the latter.
