Dataset-a dataset includes all the screens associated with a particular publication or pre-publication document. A single publication may have 1-100s of screens associated with it.

Screen-a set of gene level quantitative scores derived from a single experiment. In ORCS screens are named with a number and PMID in order to differentiate them from any other screens in the same publication. For example, if an author published the quantitative gene level scores from an experiment in which a cell line was screened with an sgRNA library and exposed to a drug and also a separate experiment in which the drug was withheld these screen results would both be curated as 1-PMID1234567 and 2-PMID1234567
