Remember the big discussion about how to ensure that information about genebank accessions can be linked back to the accession itself? Our friend Dr Dag Endresen has written a handy guide to Digital Object Identifiers (DOIs) as they might be used by genebanks. In addition to explaining how the system works, he points out that it might be a good idea for one organization to fork over the roughly USD1000 to register a top-level DOI name such as genesys. (Bioversity? The Trust? The Treaty? Is anyone listening?) That would not stop any other genebank flush with cash from registering their own domain, and it would provide something to the data providers at genebanks in return for their data. Dag discusses some other options on his blog, and I’m sure there’ll be lots of discussion there, or here, or some other place. Either way, the sooner some similar system is adopted, the sooner we can trace our collective way out of genebank database hell and satisfy the needs of those who want to link data to accessions.
