What is a DOI?
DOI stands for Digital Object Identifier. 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, webs pages, data and other digital resources. Read more about DOIs here. STScI now provides journal authors DOIs to create unique permanent links to MAST data.
Why use a DOI?
DOIs provide easy access to specific data sets, providing others fast, efficient, and durable access to your data.
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 is also 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 collaborate 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.
How do I create a DOI for my MAST data?
If your manuscript uses MAST data either downloaded directly from MAST or as part of an High Level Science Product (HLSP) follow these instructions to mint a DOI, or to find an existing DOI for the data set you use.
Who do I contact regarding DOIs?
What if I want to make a DOI for non-MAST data?
There are services that provide free DOIs and hosting for scientific data, such as Dataverse and Zenodo.
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 the data.
Examples of MAST DOIs.
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 or the AAS Journals submission page.
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.
What if I need to edit a DOI?
DOIs can be edited with permission of MAST staff as well as permission from all publications that currently reference the DOI. It is the position of MAST and AAS Journals that the DOI should reference the the data the author intended at the time of publication, rather than any data unintentionally referenced by clerical error.
