All research outputs should be uniquely identified by a DOI. It's essential for your data and publication to be independently citable with DOI for innumerable reasons, but here are some good examples:
- Data as "supplementary materials" thoroughly undervalues the importance of the data.
- Supplementary materials are typically limited to PDF files. PDF files are an extremely poor format for ALL data formats (tables, images or text)!
- Many data repositories allow your data to be versioned, allowing datasets to grow and mature over time.
As all with all research outputs, all researchers should be uniquely identifiable via an University of Oxford affiliated ORCID. Registering your ORCID with DataCite and CrossRef provides a centralised, automatically updated bibliography of all your DOI-registered research outputs.
Open Data and Reproducible Research are central to the goals of the IDN. We thoroughly recommend that the reproducible components of your visualisation outputs (i.e. the scripts and code that generate your charts/maps/diagrams) are also deposited with DOI-issuing repositories. This creates a "citation trinity" via your ORCID between: your research data, publication, interactive visualisations.
