A biodiversity dataset graph: GBIF, iDigBio, BioCASe hash://sha256/450deb8ed9092ac9b2f0f31d3dcf4e2b9be003c460df63dd6463d252bff37b55 hash://md5/898a9c02bedccaea5434ee4c6d64b7a2

The intended use of this archive is to facilitate meta-analysis of the Global Biodiversity Information Facility, Integrated Digitized Biocollections, Biological Collection Access Service (GBIF, iDigBio, BioCASe). GBIF, iDigBio and BioCASe help provide access to biological data collections.

This dataset provides versioned provenance logs of snapshots of the GBIF, iDigBio, BioCASe network as tracked by Preston [2] between 2018-09-03 and 2023-02-02 using "preston update -u https://gbif.org,https://idigbio.org,http://biocase.org".

This publication contains two types of files: index files and provenance logs. Associated data files are hosted elsewhere for pragmatic reasons. Index files provide a way to link provenance files in time to establish a versioning mechanism. Provenance logs describe how, when, what and where the GBIF, iDigBio, BioCASe content was retrieved. For more information, please visit https://preston.guoda.bio or https://doi.org/10.5281/zenodo.1410543 .  

To retrieve and verify the downloaded GBIF, iDigBio, BioCASe biodiversity dataset graph, use the preston[2] command-line tool to "clone" this dataset using:

$ java -jar preston.jar ls --remote https://zenodo.org/record/7651831/files > /dev/null

Optionally, you can retrieve all associated data (>500GB) files using:

$ java -jar preston.jar clone https://zenodo.org/record/7651831/files --remote https://zenodo.org/record/7651831/files,https://linker.bio,https://archive.org/download/biodiversity-dataset-archives/data.zip/data/

Please note https://archive.org/download/biodiversity-dataset-archives/data.zip/data/ and https://linker.bio are Preston remotes that provided access to GBIF, iDigBio, BioCASe data files at time of writing (17 Feb 2023). These remotes can replaced with any other Preston remote(s) if needed. This may take a while depending on network speed and hardware constraints. See also https://archive.org/details/biodiversity-dataset-archives .

After that, verify the index of the archive by reproducing the following provenance log history:

$ java -jar preston.jar history

If you retrieved data files, you can check the integrity of the extracted archive by confirming that each line produce by the command "preston verify" produces lines as shown below, with each line including "CONTENT_PRESENT_VALID_HASH". Depending on hardware capacity, this may take a while.
