Direct links to figures and tables using component DOIs

We are all familiar with digital object identifiers (DOIs) provided by CrossRef to identify (and link to) journal articles. Some of us are familiar with the DOIs issued by DataCite to link to datasets. But most of us don’t know that CrossRef is also providing component DOIs that can provide persistent links to a particular table or figure in a paper. The PLoS journals use component DOIs, for example for this figure:

http://www.plosone.org/article/slideshow.action?uri=info:doi/10.1371/journal.pone.0006022&imageURI=info:doi/10.1371/journal.pone.0006022.g002

Correlations between 37 measures mapped onto first two principal components (cumulative variance = 83.4%) of PCA. doi:10.1371/journal.pone.0006022.g002. From Bollen J, Van de Sompel H, Hagberg A, Chute R (2009) A Principal Component Analysis of 39 Scientific Impact Measures. PLoS ONE 4(6): e6022. doi:10.1371/journal.pone.0006022

Linking to component DOIs is straightforward, table 1 of the paper above is 10.1371/journal.pone.0006022.t001. Unfortunately only about 300,000 of the more than 40 million CrossRef DOIs are compontent DOIs.  There are many good reasons to use a direct (and persistent) link to a specific part of a scholarly journal article. And this becomes an even more important issue once DOIs for datasets are more commonly cited.

    Total gibberish mate. You must be a teacher.

  2. Good point, thanks for bringing it up. Since the 2010 article in ISQ you reference, component DOIs at CrossRef have grown to almost 400,000. http://www.crossref.org/06members/53status.html. Still relatively small, but growing.

    Thanks for the link Carol. It would be very interesting if publishers would not just link to the figure or table, but to the dataset that is behind that table/figure.
