What is a DOI?

A Digital Object Identifier provides easy access to specific data sets, providing others fast, efficient, and durable access to your data. Papers with links to data are cited more frequently and non-durable data links tend to fail over time.

You may have seen them used in links to scholarly journal articles and in the NASA Astrophysics Data System. DOIs create permanent and unique links to text, web pages, data and other digital resources.

DOI Workflow - Paper to MAST Archive

How to get a MAST DOI

Help us provide a permanent reference to the data you used in writing your manuscript. There are two ways to add a MAST DOI:

1. Generate a DOI for a custom collection of one or more observations from Hubble, Kepler, GALEX, IUE, etc.

Use the the MAST DOI Portal to generate a DOI for one or more specific  observations, images, spectra, or time-series data generated by one of our missions: HST, Kepler, FUSE, IUE, etc. If you wish to reference data from the Kepler/K2 mission in bulk, see below.


2. Find existing DOIs for catalogs and High Level Science Products such as Kepler/KIC, GALEX/MCAT, CANDELS, K2SFF, etc.

Data from a High-Level Science Product (CANDELS, K2SFF, etc.)

High Level Science Products are pre-processed community-provided datasets that already have DOI links.  A pre-defined DOI can be found on the HLSP page next to the name of the product.


A catalog? (Kepler/KIC, GALEX/MCAT, etc.)

At present, we provide a DOI for each of the following MAST catalogs and surveys.


An entire quarter or campaign from Kepler/K2 or an entire sector from TESS?

Data from the Kepler space telescope are often referred to in large collections, either by quarter, by cadence, or as a whole. Data from TESS is referred to by sector. Find the corresponding DOI for these data collections below.
