MaveDB accession numbers

MaveDB accession numbers use the URN (Uniform Resource Name) format. The accession numbers have a hierarchical structure that reflects the relationship between experiment sets, experiments, score sets, and individual variants in MaveDB. URNs are also used to uniquely identify other resources in MaveDB, such as calibrations and collections.

URNs within the experiment set/experiment/score set/variant hierarchy start with the string urn:mavedb: followed by the experiment set number (eight digits, zero-padded). Experiments are indexed by letter within the experiment set. If necessary, aa, ab, etc. will follow z. Score sets are indexed by number within the experiment.

Meta-analysis accession numbers

Meta-analysis score sets use the special 0 experiment instead of a letter.

Meta-analysis score sets that include data from a single experiment set will use that experiment set’s number. For meta-analyses that use data from multiple experiment sets, a new experiment set number will be assigned for all meta-analyses that include data from the same experiment sets. These meta-analysis-only experiment sets will only contain the 0 experiment.

Temporary accession numbers

When first uploaded, records are given a temporary accession number starting with tmp:. These temporary accessions are not structured according to the record type.

MaveDB URNs are created when the temporary records are made publicly viewable by publishing a score set.

URNs for other resources

Other resources in MaveDB that exists outside of the data set hierarchy, such as calibrations and collections, also use URNs starting with urn:mavedb:. This is followed by a resource type identifier (e.g., calibration, collection) and a unique resource identifier. For example, the URN for a calibration resource might be urn:mavedb:calibration-11111111-2222-3333-aaaa-bbbbccccdddd.
