Re: [tdwg-content] If you need something for referring to a population, then it is probably best to do it as a related class

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. Some of this also on p. 47 of this PDF: https://journals.ku.edu/index.php/jbi/article/view/3927/3852 > > /Aedes triseriatus/ owl:sameAs /Ochlerotatus triseriatus/ > > Others seem to see them as phylogenetic end nodes which entail a > specific phylogenetic history. > > /Aedes triseriatus/ distinctFrom /Ochlerotatus triseriatus/ > / > / > If you are primarily interested in understanding issues of ecology, > disease, diversity and conservation the former model is more > appropriate than the later. > > Respectfully, > > - Pete Regards, Nico Nico M.

Questions without answers - oh no! Darwin Core Hour needs your help
by Deborah Paul 06 Dec '17

06 Dec '17

Hi Everyone, It's your chance to make someone's day. Please help us tackle the backlog of questions we have in our Darwin Core Hour website. This is your opportunity to do a good deed and make someone happy at the same time. Sharing your expertise makes this project work. Thank you for your contribution. You can also help by passing along this note to others you know could answer these outstanding questions. If you feel you cannot answer a question fully, don't be shy - share the knowledge that you have anyway. Multiple people can answer the same question, each one contributing their grain of sand. New Tickets Needing Answers <https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_tdwg_dwc-2D…> Some of them are tangential to the Darwin Core Hour Scope - and so we need to do this outreach to help our community find the knowledge they need to support their data mobilization efforts. We very much appreciate your help. Please also consider joining our Darwin Core Hour Team for 2018. Thank you, Muchas gracias, Kiitos paljon, Merci, Grazie, Domo arigato, Vielen Dank, Spasiba, ...

Darwin Core Hour: Audubon Core and 3D Biodiversity Data - Tuesday 21 November 2017 3 PM EST
by Deborah Paul 04 Dec '17

04 Dec '17

Hello Everyone! Got 3D data and image files? How are you sharing, storing, and managing these media information resources and metadata? Wondering what others are doing to make media, and 3D in particular, more accessible? From the scientific collections perspective, please join us for our upcoming Darwin Core Hour Webinar: Audubon Core and 3D Biodiversity Data: Metadata, Practice, and Unification of Efforts We encourage people to bring or submit questions for discussion section of webinar. https://bit.ly/dwchour-input Date: Tuesday 21 November 2017 Time: 3pm EST, 12pm PST, 5pm ART, 9pm CET, 20:00 UTC Where: http://idigbio.adobeconnect.com/room Abstract: A growing mode of digitization of natural history collection objects is 3D digitization, which includes three main acquisition techniques: surface scanning (structured light or laser scanners), volumetric scanning (microCT or MRI), and photogrammetry (structure from motion). There is now burgeoning interest in and tremendous need for describing 3D data files with standard vocabularies in the interest of promoting broad accessibility and long-term digital preservation. Audubon Core is an existing vocabulary and extension to Darwin Core that is used to describe digital media files representing natural history objects. It is not an entirely new vocabulary with many terms borrowed from Dublin Core, Darwin Core and more. It also intended to describe different kinds of digital data representing different creation methods and file formats. We overview several different 3D data collection modalities specifying the details needed for understanding how 3D data was generated and processed. We investigate the utility of Audubon Core for describing these 3D modalities. Questions we ask are which existing terms can be used for describing new 3D modalities, whether new terms are needed, whether certain 3D modalities need specific terms not applicable to other modalities, what 3D data formats should be emphasized for preservation and access, and how to pursue formally acquiring new terms either through creation of new vocabularies or extending existing ones. Presenters Gary Motz - Chief Information Officer and Assistant Director for Information Services, Indiana Geological and Water Survery Doug Boyer - Assistant Professor, Department of Evolutionary Anthropology, Duke University; MorphoSource Moderator - Holly Little, Informatics Manager, Paleobiology Collections, Smithsonian Relevant links https://terms.tdwg.org/wiki/Audubon_Core_Term_List http://morphosource.org/ Darwin Core Hour Series Abstract: Darwin Core has become a broadly-used standard for biodiversity data sharing since its inception as a standard by the organization Biodiversity Information Standards (TDWG) in 2009. Despite, or because of, its popularity, people trying to use the standard continue to have questions about how to use Darwin Core and associated extensions. This webinar series looks at open questions related to Darwin Core. Though the topic is broad, individual chapters in the series will focus on specific topics to any adequate level of depth. We encourage people to bring or submit questions and to have open discussions in each webinar (https://bit.ly/dwchour-input) See https://github.com/tdwg/dwc-qa/wiki/Webinars for our webinar resources.
