Why use a DOI?
What is the MAST DOI Initiative?
The MAST DOI Initiative is a system at MAST for assigning, preserving, and dereferencing DOIs for MAST data. It began with a partnership with American Astronomical Society Journals (The Astrophysical Journal, The Astronomical Journal, The Astrophysical Journal Supplements, and The Astrophysical Journal Letters) in which MAST and AAS Journals collaborated to bring MAST DOIs to AAS Journal articles. At present, only authors at STScI are being asked to provide DOIs to their MAST data in the publication process. In 2018, additional pilot institutions will be prompted to provide MAST DOIs during submission to AAS journals. Eventually, all authors will be asked to provide MAST DOIs on submission to AAS journals in the future.

What if I want to make a DOI for non-MAST data?
Am I allowed to use MAST DOIs on ArXiv? Other publications?
While MAST does not have any explicit agreements in place with other publishers, you may use a MAST DOI in any way you see fit. We would be happy if you used it in any publication referencing MAST data.
How do I cite an HLSP or an already-established DOI?
High Level Science Products, entire catalogs (like the Hubble Source Catalog) and certain collections of data (specific subsets of Kepler and K2 data) have pre-assigned DOIs that can be found on the HLSP page or the MAST DOI Home page. You can directly copy the DOIs provided for these data sets and insert them into your manuscript. When entering the url, be sure to use the standard url prefix, e.g.,
Examples of MAST DOIs.
High-Level Science Product (pre-assigned DOI): CANDELS,

Catalog Example (pre-assigned DOI): EPIC/K2 Catalog,

Entire Quarter or Campaign from Kepler/K2 (pre-assigned DOI): Kepler Long Cadence data, Quarter Three,


Associated manuscript: HST/COS Observations of Ionized Gas Accretion at the Disk-Halo Interface of M33 (Zheng, Y; et al)

Data from Faint Infrared Grism Survey (FIGS) (reserve DOI for newly generated, community contributed High-Level Science Product):

Associated manuscript: FIGS—Faint Infrared Grism Survey: Description and Data Reduction (Pirzkal, N; et al.)
Can I create more than one DOI? Should I?
You may create more than one DOI for your manuscript. We suggest that you create DOIs for each dataset that is discussed independently in the manuscript. If data sets are analyzed in conjunction they should be put into the same DOI. We recommend that you not generate many DOIs with similar content; don’t generate one for each target. If you discuss, for instance, FUSE and HST data that a reader would most likely want to access independently, you can create a separate DOI for each of them.
Are DOIs citable?
While DOIs can be referenced by journals they are not kept track of like articles or other “first-class citable objects”. Thus, MAST DOIs do not accrue citations in the same way articles do. MAST DOIs should be thought of more like “permanent URLs” than scholarly works.
