Some of the work that they've done may help with processing of external databases. They unify some of the drug/target concepts in DrugBank and PharmGCB, for example, by developing abstract representations of genes, gene products, variants, etc.
Thanks for the recommendation . Unless there is a specific contribution that this resource could immediately provide, I am wary to invest significant time in understanding and integrating it.
My initial sense is that while this study tackles some important problems in biodata integration, there isn't a readily available way to easily retrieve and incorporate the unified vocabularies. It would be great to get feedback from the authors, in case I am wrong.
