13. Summary Preliminary results
Accession as a helpful abstraction for managing touchable real world entities ('samples') (< more then one sample per accession is stored, samples can derive from different maintenance methods)
Customers of a gene bank are not interested in a special representation of an accession but in specific traits of all representatives (< accessions as carriers of passport and characterisation information)
