Thanks very much, this is helpful feedback.

On a related note, Harvard-IQSS created a platform called Dataverse (https://dataverse.org/about) around 2007 and one interesting element is that they published a method for hashing datasets. This is done for the purpose of creating a citation element that can be used to verify that you have downloaded the same data. Passing along in case this is of interest to the group:

I might also add that every download from GBIF.org–be it a single dataset or an aggregate–is archived and given a unique, persistent DOI for citation. And that citations of downloads count against all the datasets that contributed to that download.

While it would be great to have versioned datasets I generally create a snapshot of the data used in a paper and archive this in Zenodo. This gives complete reproducibility without putting extra demands on the data providers. I do however need to cite the source and the snapshot. Regards Quentin

This is just a quick answer which I expect will result in follow up questions.

In terms of citation, we use a DOI to identify the concept of a dataset, not the specific version. E.g. https://doi.org/10.15468/cup0nkhttps://urldefense.proofpoint.com/v2/url?u=https-3A__doi.org_10.15468_cup0nk&d=DwMGaQ&c=WO-RGvefibhHBZq3fL85hQ&r=CdeDWKDCq4utpRBAQsRWPsFEuA9hFIpReg9XUuWRHOA&m=QAbsRjSWihrdVjG7RYt6giVaADF8smdKP1WZnbfukuc&s=gxEzg7QhLSvKKIBG7rDac6LWCKd-bjMirk5DHQx2y9I&e= If you start deleting copies of data (e.g. a background housekeeping task) what will break are links to the downloads in the IPT pages. https://ipt.huh.harvard.edu/ipt/resource?r=huh_all_records&v=1.3 This may or may not be considered a problem for you.

I think others might have contacted you about suggestions for improving the dataset titles being used but if not I would suggest considering correctly formatted titles as they are used in many places (https://www.gbif.org/dataset/4e4f97d2-4670-4b24-b982-261e0a450faf)https://urldefense.proofpoint.com/v2/url?u=https-3A__www.gbif.org_dataset_4e4f97d2-2D4670-2D4b24-2Db982-2D261e0a450faf-29&d=DwMGaQ&c=WO-RGvefibhHBZq3fL85hQ&r=CdeDWKDCq4utpRBAQsRWPsFEuA9hFIpReg9XUuWRHOA&m=QAbsRjSWihrdVjG7RYt6giVaADF8smdKP1WZnbfukuc&s=hLi2fk3gePaQiOUHBC7Lb3KNPFmLiRKgOlK1tdYUqFA&e=.

I hope this helps as a start, Tim

Hi All,

I am finishing an upgrade to the Harvard University Herbaria IPT instance and have configured our feeds for daily auto-publish. The HUH has invested in a mass digitization workflow and we are currently creating ~20,000 new vascular records per month (with minimal data), so we do have new records on a daily basis. However, our DwC archives are fairly large (100MB+), so we can’t keep the daily archive history. I am looking for guidance on how it will work with GBIF dataset citation if we do not preserve each daily archive. It seems problematic if a version of our dataset is used and cited but cannot be reconstructed.
