Abstract: The present disclosure is directed to managing and accessing experiment data. A data processing system may generate a system identifier for each instance that leads to a generation of experiment data. A first segment may refer to a source entity, and may be used to differentiate identifiers generated by different source entities. This implementation may aim to provide an explicit representation of the data generation process while providing a glimpse on select metadata attributes, such as an individual species, sample class, and experimental technique used to generate the dataset. These constraints may prevent duplicates and may enable system-side associations among subjects, samples, aliquots, and experiments.
