Soliciting commentary on Darwin Core-related schema maintenance
by John Wieczorek 17 Feb '26

17 Feb '26

Dear Technical Architecture Group, First attempt to post didn't go through. Today I opened an issue <https://github.com/tdwg/dwc/issues/815> in the context of the current Darwin Core public review highlighting a clause in the Darwin Core Data Package Guide that requires institutional decisions and potentially an MOU. I wanted you all to be aware of this issue so you can comment on it directly if you have insights. Cheers, John

New TDWG Constitution submitted to the membership for review
by Stanley Blum 13 Sep '16

13 Sep '16

[ Please excuse the duplicate posts of this important announcement. ] TDWG Executive Committee proposes a new Constitution. In 2015, the TDWG Executive Committee commissioned a team to assess TDWG's structure and effectiveness, and to propose changes to the TDWG Constitution as needed. That work is now complete, and the Executive Committee has advanced the proposal to the membership for review. The revised Constitution aims to engage more people in the ongoing activities of TDWG, and to promote continuity in governance across years. If the proposed Constitution is adopted, new committees will be created and charged with ongoing responsibilities, and new officers will be elected to lead those committees. Read more about the motivation and the detailed changes here <http://www.tdwg.org/about-tdwg/new-constitution/> and in the Review Package <http://www.tdwg.org/fileadmin/tdwg/about-tdwg/tdwg-constitution-2016__packa…> . The 90-day review period began on 06-Sep-2016, with publication of theReview Package <http://www.tdwg.org/fileadmin/tdwg/about-tdwg/tdwg-constitution-2016__packa…> on the TDWG website. It will end with with the close of electronic voting on 06-Dec-2016. Each member is encouraged to read the proposal and assess the changes against the rationale presented in the package. Comments can be sent to the TDWG secretary (secretary [at] tdwg [dot] org) until 30 days prior to the close of the vote. (Additional information about comments and the comment period will be posted on the proposal page of TDWG website <http://www.tdwg.org/about-tdwg/new-constitution/> before 30 Sep.) Voting will be electronic. Each member in good standing[1] will receive an electronic ballot, and will be entitled to one vote (approve/disapprove). A majority of votes cast in each membership category, individual and institutional, will be required to adopt the new Constitution. On behalf of the Executive Committee, Dimitrios Koureas, TDWG Secretary Stan Blum, TDWG Coordinator [1] To be a member in good standing, at least one of the following must be true: 1) you paid TDWG membership dues in either 2015 or 2016; 2) you attended the annual meeting in 2015; or 3) you have paid registration fees to attend the annual meeting in 2016. Please inquire with the TDWG Treasurer (treasurer [at] tdwg.org) if you would like to confirm your membership status.

DwC-A and JSON
by Bob Morris 24 Aug '15

24 Aug '15

Is there or should there be a form of DwC-A serialized with JSON? If no, should Interest Group X ( X= ???) initiate some discussion or Task. If IG X is already at work, where is its discussion? Alternatively, should my question be something like "What is the JSON alternative to DwC-A and where is it, or should it be, discussed?" Thanks Bob -- Robert A.

"Class" attribute in DwC
by Bob Morris 18 Aug '15

18 Aug '15

The current DwC Terms [1] (carrying Identifier http://rs.tdwg.org/dwc/2015-03-19/terms/ and Date Modified: 2015-06-02 ) is confusing (confused? silent? ) about the relation of the "sister classes" to the terms intended (?) to be used therewith. For example, dwc:Event, dwc:MachineObservation, and dwc:HumanObservation could reasonably(?) all have dwc:eventDate applied to them. But http://rs.tdwg.org/dwc/terms/index.htm#eventDatesuggests Class=dwc:Event. Now it's human-clear that for each of the "multiple" boldface lines in the index, the second and subsequent terms are meant to be special cases of the left most one. What I can't see is whether [1] intends to encourage (require?) this in some explicit way, and where that explicit way is to be found. (I had a dream that the DwC RDF Guide might take a position....) . Thanks. --Bob p.s. I concede that some answers might lurk in the ongoing move of resources to http://tdwg.github.io/dwc/terms/. My second dream was that tdwg.github.io does Content Negotiation and curl would rescue me.... [1] http://rs.tdwg.org/dwc/terms/index.htm -- Robert A.

terms for sample data in DwC
by Éamonn Ó Tuama [GBIF] 07 Nov '14

07 Nov '14

In compliance with the directions for requesting changes to the Darwin Core (DwC) vocabulary, we hereby submit to the TDWG Technical Architecture Group a proposal for five new terms to express information on sample-based data. Sample-based data is a type of data available from thousands of environmental, ecological, and natural resource investigations. These can be one-off studies or monitoring programmes. Such data are usually quantitative, calibrated, and follow certain protocols so that changes and trends of populations can be detected. This is in contrast to opportunistic observation and collection data which today form a significant proportion of openly accessible biodiversity data. Sample-based data are often not shared because the underlying protocols have been hard to encode in a standardised way. For further background information and examples, please consult the sample data primer document [1]. We cannot emphasise enough that our intention here is not to establish how data should be captured or modelled but rather demonstrate one way data can be exposed to maximize discoverability and reuse. In particular, GBIF, in association with EU BON [2] project partners, is exploring how the IPT and Darwin Core Archives can enable the flow of sample based data in support of GEO BON Essential Biodiversity Variables (EBVs) [3]. While DwC already provides many terms that are relevant for describing sample-based data, based on several inputs (GBIF organised workshop on sample data, May 2013 ; previous discussions on the TDWG mailing list; discussions on the EU BON mailing list), we have identified a need for five new terms. These are: sampleSize <https://github.com/tdwg/dwc/issues/10> https://github.com/tdwg/dwc/issues/10 #Justification Required for sharing organism abundance data from controlled sampling and monitoring surveys (i.e., sampling events). For an introduction to the sampling proposal please see <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer. #Definition A numeric value for the time duration, length, area or volume involved in the sampling event. #Comment The terms sampleSize and sampleSizeUnit are required to be used as a pair. The value of sampleSize is a number. Example: 5 for the value part of 5m. #Term group Event sampleSizeUnit <https://github.com/tdwg/dwc/issues/11> https://github.com/tdwg/dwc/issues/11 #Justification Required for sharing organism abundance data from controlled sampling and monitoring surveys (i.e., sampling events). For an introduction to the sampling proposal please see <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer. #Definition The unit of measurement used in the sampling event. #Comment The terms sampleSize and sampleSizeUnit are required to be used as a pair, e.g., 5 metre. Example values of sampleSizeUnit include minute, hour, day, metre, square metre, cubic metre. Recommended best practice is to use a controlled vocabulary such as the Ontology of Units of Measure <http://www.wurvoc.org/vocabularies/om-1.8/> http://www.wurvoc.org/vocabularies/om-1.8/ of SI units, derived units or other non-SI units accepted for use within the SI (e.g. minute, hour, day, litre). Example: metre for the unit part of 5m. #Term group Event quantity <https://github.com/tdwg/dwc/issues/12> https://github.com/tdwg/dwc/issues/12 #Justification Required for sharing organism abundance data from controlled sampling and monitoring surveys (i.e. sampling events). For an introduction to the sampling proposal please see <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer. #Definition The quantity, per sampling event, given as a number or enumeration value for the quantityType. #Comment The terms quantity and quantityType are required to be used as a pair. The value of quantity is a number or enumeration. Examples: 12.5, r #Term group Occurrence quantityType <https://github.com/tdwg/dwc/issues/13> https://github.com/tdwg/dwc/issues/13 #Justification Required for sharing organism abundance data from controlled sampling and monitoring surveys (i.e., sampling events). For an introduction to the sampling proposal please see <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer. #Definition The entity to which the number or enumeration reported in quantity refers. #Comment The terms quantity and quantityType are required to be used as a pair, e.g., 14 individuals. The value of quantityType (i.e., the entity being measured) is expected to be drawn from a small controlled vocabulary. Examples: Individuals, % Biomass, % Biovolume, % species, % coverage, BraunBlanquetScale, DominScale. #Term group Occurrence parentEventID <https://github.com/tdwg/dwc/issues/9> https://github.com/tdwg/dwc/issues/9 #Justification Allows arbitrary linking of sub sampling events, e.g., for nested sampling plots. This was demanded by several people during the discussion of the TDWG sample based data session. For an introduction to the sampling proposal please see <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer. #Definition An event identifier for the super event which is composed of one or more sub-sampling events. #Comment The value must refer to an existing eventID. If the identifier is local it must exist within the given dataset. Example: A1 identifying the main Whittaker Plot in nested samples, each with their own eventID (e.g., A1:1, A1:2). #Term group Event None of the existing DwC terms is sufficient for any of the proposed terms although two are somewhat related: sampleEffort ("The amount of effort expended during an Event") and individualCount ("The number of individuals represented present at the time of the Occurrence"). Neither are adequate sampleEffort just provides a free text statement so is hard to parse in comparison to sampleSize and sampleSizeUnit and individualCount refers exclusively to individuals and not percentages or entities like biomass, biovolume, etc. [1] <http://links.gbif.org/ipt-sample-data-primer> http://links.gbif.org/ipt-sample-data-primer [2] <http://eubon.eu/> http://eubon.eu [3] <http://www.earthobservations.org/documents/cop/bi_geobon/ebvs/201301_ebv_pa per_pereira_et_al.pdf> http://www.earthobservations.org/documents/cop/bi_geobon/ebvs/201301_ebv_pap er_pereira_et_al.pdf ____________________________________________________ Éamonn Ó Tuama, Markus Döring, GBIF Secretariat

another poke about Audubon Core status
by Stoner, Dan 29 Sep '14

29 Sep '14

I see in the tdwg-tag mailing list archives that the status of the Audubon Core Standard has been discussed recently: http://lists.tdwg.org/pipermail/tdwg-tag/2014-June/002558.html So consider this another poke about getting the web site updated with the official status of the Standard. If there is anything I can do to facilitate the web site update, please let me know (as in, I am volunteering to hack code or whatever is needed). Thanks, Dan Stoner iDigBio / ACIS Laboratory University of Florida

Re: [tdwg-tag] [tdwg-content] [tdwg] another poke about Audubon Core status
by Bob Morris 23 Sep '14

As to Audubon Core (AC), a little clarification is needed. The only thing so far adopted is the AC data model, more precisely "The Audubon Core Multimedia Resources Metadata schema (“AC schema”, or simply “AC”) is a set of metadata vocabularies for describing biodiversity-related multimedia resources and collections. The specification is independent of how these vocabularies may be represented for machine use." [1] In particular, no artifacts akin to such things as the DwC normative document [2] have been submitted for approval, nor have artifacts akin to Simple Darwin Core [6] though some are under development (*, **). In appearance, the AC documents [1, 3 and 4] together are a bit like the most useful reference for DwC, namely [5]. But unlike [5], [3 and 4] are normative ([1] is not/). Those parts of AC are maintained in a MediaWiki, and would be relatively pointles to put in a public source code repository, perhaps except based on arguments of backup sustainability. In such a case, they would be of use only to AC maintainers, unless the repo happened to support MediaWiki. Bob Morris TDWG Image Interest Group co-convenor and AC <co-something or other> [1] http://terms.tdwg.org/wiki/Audubon_Core#Introduction [2] http://rs.tdwg.org/dwc/rdf/dwctermshistory.rdf [3] http://terms.gbif.org/wiki/Audubon_Core_Structure [4] http://terms.tdwg.org/wiki/Audubon_Core_Term_List [5] http://rs.tdwg.org/dwc/terms/ [6] http://rs.tdwg.org/dwc/xsd/tdwg_dwc_simple.xsd (*) Readers beware: [2] is an RDF description of Darwin Core, not an RDF description of biodiversity. (**) There will be a session devoted to AC at TDWG 2014 which will hopefully be attended by those already using AC in one or another specific, albeit unsubmitted form.

Just quickly, I got a short statement of work and budget worked out with the potential contractor last winter, but let the project go cold. That was entirely my fault. I had a couple contacts with them through the rest of the year just to maintain contact, and then started to push in late August. Key people were on vacation then, and since I’ve been pushing sending emails and making phone calls trying to get the project started. But I’ve only gotten one response, they’re still interested, but they didn’t tell me when we could start. If anyone knows another Typo3 contractor, I’d be happy to engage with them instead. (The one I’ve been trying to engage is in SF… so I should go knock on their door instead of sending email and phoning.) I’m going to keep trying… -Stan From: tdwg-content-bounces(a)lists.tdwg.org<mailto:tdwg-content-bounces@lists.tdwg.org> [mailto:tdwg-content-bounces@lists.tdwg.org] On Behalf Of James Macklin Sent: Monday, September 22, 2014 8:59 AM To: Bob Morris Cc: tdwg(a)lists.tdwg.org<mailto:tdwg@lists.tdwg.org>; TDWG Content Mailing List; tdwg-tag(a)lists.tdwg.org<mailto:tdwg-tag@lists.tdwg.org>; Dave Vieglais Subject: Re: [tdwg-content] [tdwg] [tdwg-tag] another poke about Audubon Core status I am also in favor of the GitHub repo but we really need to hear from Stan about the status of the work he was having done on the TDWG site.
