DataONE is a federated data network focusing on earth and environmental science data. We present the provenance and search features of DataONE by means of an example involving three earth scientists who interact through a DataONE Member Node. DataONE provenance systems enable reproducible research and facilitate proper attribution of scientific results transitively across generations of derived data products.

The DataONE federated data network has adopted and extended the PROV model to support the collection, storage, indexing, and user browsing of the provenance of data packages stored in its member nodes. The PROV extension, ProvONE, adds provenance elements (entity and relationships types) for describing process structure alongside the data dependencies that originate from process execution. The ProvONE model was defined in 2015 and its specification is available online [1], while provenance support based on the model is now (2016) in its pre-production phase.
