A dataset is a list of occurrences created and/or curated by a user. Datasets may be used to keep track of specimens associated with certain inventory, research, data curation, or interest projects. For example, a researcher might save a datset consisting of all the occurrence records they used in a particular analysis, a collector might save a dataset consisting of all specimens from a particular collecting trip, or a collection manager might save a dataset of all the specimens that they need to physically inspect for curation purposes. Some examples in practice can be found here and here.

Datasets can be private or publicly available.
