Anno 2017 the task of mobilizing data from biocollections ahead of us is still enormous (data of 90% of the biocollections still needs to be mobilized). It is imperative for stakeholders, individual keepers of natural science collections, the community at large, and even for funding agencies, not only to tackle this backlog as quickly as possible, but do it in the best possible order. To establish the best possible order for digitizing biocollections a demand driven framework is required based among others on criteria used to digitize biocollections.
