A Biodiversity Dataset Graph: Gbif, Idigbio, Biocase

Biodiversity datasets, or descriptions of biodiversity datasets, are increasingly available through open digital data infrastructures such as Global Biodiversity Information Facility (GBIF, https://gbif.org), Integrated Digitized Biocollections (iDigBio, https://www.idigbio.org) and the Biological Collection Access Service (BioCASE, http://www.biocase.org). However, little is known about how these networks, and the data accessed through them, change over time. This dataset provide snapshots of the biodiversity dataset graphs as tracked by Preston (https://github.com/bio-guoda/preston , https://doi.org/10.5281/zenodo.1410543 ). The rdf/nquad and tsv snapshots were generated using the respective commands: preston ls | bzip2 > preston-ls.nq.bz2 and preston ls --log tsv | bzip2 > preston-ls.tsv.bz2 For convenience, the first 100 uncompressed entries of both files are included, as well as the sha256 hashes of the content of the files.
