13 years after How Do You Manage Your Files & Directories For Your Projects ? , I wrote a tutorial about how I now manage my data : BAM, VCF, sample, phenotype, reference etc... how to link everything with RDF and how to query with SPARQL.

See https://github.com/lindenb/hts-rdf/

An example for biostars:

find the BAM files , their references, samples , etc..

SPARQL query
