As you may suspect, my concerns are focused on the preservation of the semantics of the field names, Sam1, Sam2, Sam3, but also with the field names that will be generated by the requesting researcher.
I found this video embedded in: A call for open access to all data used in AJ and ApJ articles by Kelle Cruz.
From the post:
I don’t fully understand it, but I know the Astronomical Journal (AJ) and Astrophysical Journal (ApJ) are different than many other journals: They are run by the American Astronomical Society (AAS) and not by a for-profit publisher. That means that the AAS Council and the members (the people actually producing and reading the science) have a lot of control over how the journals are run. In a recent President’s Column, the AAS President, David Helfand proposed a radical, yet obvious, idea for propelling our field into the realm of data sharing and open access: require all journal articles to be accompanied by the data on which the conclusions are based.
We are a data-rich—and data-driven—field [and] I am advocating [that authors provide] a link in articles to the data that underlies a paper’s conclusions…In my view, the time has come—and the technological resources are available—to make the conclusion of every ApJ or AJ article fully reproducible by publishing the data that underlie that conclusion. It would be an important step toward enhancing and sharing our scientific understanding of the universe.
Kelle points out several reasons why existing efforts are insufficient to meet the sharing and archiving needs of the astronomical community.
Suggested reading if you are concerned with astronomical data or archives more generally.
