Public review of Darwin Core conceptual model and data package extended
by Stan Blum 15 Dec '25

15 Dec '25

Discussion of the Darwin Core Data Packages (DwC-DP) proposal has ticked up over the last few weeks, so the ongoing public comment period will continue beyond the originally announced 90 days, which would have ended on December 15. If you are unfamiliar with the functioning of public comment periods for vocabulary changes, please review Section 3.3.2 of the Vocabulary Maintenance specification <https://tdwg.us9.list-manage.com/track/click?u=50f3cc44307841383062ca0d6&id…>. To summarize briefly, if there is dissent about a proposal, the proposal may be modified in an attempt to achieve consensus. Any such modification triggers a reset of a 30 day clock to give people sufficient time to consider the modified proposal. Because of this mechanism, it is possible for a small number of people to delay the acceptance of a proposal that is as large and complex as DwC-DP for a long time. In the case of DwC-DP, there are a large number of smaller individual proposals that are being considered as a package, and modification of any one of the individual proposals will delay the acceptance of the overall package for another 30 days. The Darwin Core Maintenance Group is committed to a fair and open review process of the DwC-DP, and will allow the public review to continue for as long as necessary to achieve consensus. So as long as there is active discussion, we will keep the public comment period open. However, because there is keen interest in the community from people who want to use DwC-DP in ratified form, we'd prefer that the review not drag on indefinitely due to people not getting around to reviewing it in a timely fashion. Therefore, if you have not yet reviewed the proposal, I ask that you do so and submit your comments by January 16. If those comments do not result in any changes in any part of the proposal after that date, the public comment could end on February 15 (30 days later). Continuing discussion after January 16 would cause the comment to continue correspondingly longer, and that's fine if the discussion continues to improve the proposal. We have gotten many excellent and substantive suggestions so far that have improved the proposal, and I am grateful for those who have taken the time to thoughtfully review and comment. I am hopeful that we will soon have a strong final proposal that the Task Group will be able to recommend ratification by the Executive Committee. Sincerely, Steve Baskauf Darwin Core Maintenance Group convener

Dear All, We are writing to you as researchers from the University of Regina in Regina, Canada who are studying open data. We invite you to participate in the Open Data Community Survey 2025 if you use or provide open data or FAIR data or if you are interested in using semantic metadata to improve the usability of your data. The survey is estimated to take 15-20 minutes to complete, and it is available at the following link:https://uregina.eu.qualtrics.com/jfe/form/SV_2ryvDaooieWaAjY Your responses will provide invaluable insights into the state of the open data community in 2025. You may choose to answer as open data user or provider if one of those roles dominates your time or both if they make equal demands of your attention. Please help to improve the power of the survey by sharing this invitation to participate widely within your networks. However, there is no obligation for you to pass along this invitation, and there will be no penalty to you if you do not share it.

Round-tripping Data Feedback at TaxonWorks Together 2024
by Deborah Paul 26 Nov '25

26 Nov '25

Greetings All, RE: Balancing Global Agency and Local Precision. Roundtrip your feedback at TaxonWorks Together 2024 Presenter: David Shorthouse Where: online, free Register: https://together.taxonworks.org/ When: 8 May 2024 (next Wednesday) at 15:00 UTC (10:00 CDT). Many of us, as data providers and data aggregators need to both give and receive feedback about our data. A new proposed Darwin Core term: feedbackURL could provide a feasible -- actionable -- step forward. See SEE: https://github.com/tdwg/dwc/issues/180 <SEE: https://github.com/tdwg/dwc/issues/180>. If you'd like to learn more about this and how it might work for you, if you'd like to add to the conversation, please join us at TaxonWorks Together for the talk: Balancing Global Agency and Local Precision. Roundtrip your feedback. David Shorthouse presents this topic to share his take and insights on the potential in this term for all of us. It's exciting to be talking about implementing solutions that could help data providers get feedback directly. Hope to see you there! Note there are related sessions you might find interesting: * A Data Quality Round Table Conversation: with GBIF, iDigBio, TaxonWorks, the Paleo Data Working Group, Robert Mesibov, and You o From data quality (e. g. completeness, consistency, compliance), to data management, expect an in-depth congenial local-to-global conversation. From the data aggregator, to the working group, the researcher, the collection / data manager, and the data analyst, what do we each experience, what do we dream of? How is data-quality an outcome of processes? Looking for alignment opportunities. * A Look Inside One’s (TaxonWorks) Data o What’s in those buckets anyway in your database fields? How do you know where to find issues? When and how do you find snafus and how do you fix them? We explore the promise of the new Project vocab and Field Synchronize tasks in TaxonWorks. What are your processes and needs for doing this work to enhance and extend your data? How has the evolution of TaxonWorks illuminated outstanding data-quality challenges and what does it offer to make it eas(ier) to address them? + (pssst: if you know you me, you'll have heard me talk about visualizing the data in your databases, come see to get a taste of what this is making possible). Your questions, welcome. Looking forward to seeing you there!

The fact that human may disagree on what > species it is a human issue. > > Again, Are we modeling species or variations in human > conceptualizations of species? NMF: I believe there is a history of biodiversity database engineering that actually led some people, initially in Australia (Greg Whitbread?) and Europe (Berendsohn's group) to place more emphasis on modeling human conceptualizations of taxa. I understand this happened in the late 80s / early 90s. The motivation was, apparently, that no long-term consensus seemed available to model a single and sufficiently widely accepted taxonomy of, say, Central European vascular plant species or mosses. I believe that projects such as the Euro + Med PlantBase (http://www.emplantbase.org/home.html) are examples of the persistence (success?) of this 20+ year old practice. I think this is the kind of background that Steve is referring to. > > Which of these is of primary importance to decision makers and > non-taxonomist biologists? > Part of the problem with various publications relating to ontologies > and taxonomy is that their species models entail a specific > phylogenetic hypothesis. > > In the real world taxa are not as clean as some would like to make > them out to be. > > Each individual is a unique combination of thousands of separate gene > lineages which often do not follow clean monophyletic paths. > > I would argue that most of those who work with species related data > see them as useful typological constructs which in general follow the > biological species model. NMF: The solution of how to properly model things such as species in RDF, OWL (etc.) should ideally accommodate all "species concepts" (BCS, ESC, PSC, GSC, there's dozens), i.e. it should be neutral towards this issue. The examples below are too simple, ignoring for example cases such as pro parte synonymy, or a concept ("species") that appears unique and monophyletic to one author but (vastly) polyphyletic to another. To do an accurate mapping in that latter case (which is not super-common but it's real), I think one would have to come down on saying we're modeling human conceptualizations. They are not just that, so really it's not a strict dichotomy, meaning that by modeling conceptualizations we do not have to say "the species only exist on our heads", or "well, then anything goes". I agree (sheepishly) that it does come down to what the input data look like, and what the expectations are towards just accommodating the user community versus pushing them in a particular direction.
