10 years ago Data papers are flourishing as a new article type in journals such as \emph{F1000Research}, \href{http://www.internetarchaeology.org/}{\emph{Internet Archaeology}}, and \href{http://www.gigasciencejournal.com/}{\emph{GigaScience}}, as well as in dedicated journals like \href{http://www.earth-system-science-data.net/}{\emph{Earth System Science Data}}\cite{pfeiffenberger_earth_2011}, \href{http://onlinelibrary.wiley.com/journal/10.1002/%28ISSN%292049-6060}{\emph{Geoscience Data Journal}}, Nature Publishing Group's \href{http://www.nature.com/scientificdata/}{\emph{Scientific Data}}, and a trio of ``metajournals'' from Ubiquity Press.
In the first paragraph of "Data as the subject of a paper" you list a number of quite representative examples of data journals, but manage to omit the probably first example of a "pure" data journal (with peer review of data), ESSD, founded in 2008. A brief summary of ESSD's rationale and approach was published 2011 in D-Lib Magazine, doi:10.1045/january2011-pfeiffenberger
