I think Matt hit the nail on the head. Although Darwin Core can be used to exchange survey data, it lacks the semantics and structure necessary to archive the data without loss of information. I think the biodiversity community would be better served devoting energy to harmonizing existing technologies such as OGC, OBOE, and BCO, not to mention the many database for storing plot or survey data. The goal should be to preserve the data in the most informative manner possible. There is a strong a case for wanting to search across all evidence for occurences, including surveys and point occurences, so I can see possible demand for a tool that would extract occurences from survey data to a DwC archive. However, I am very concerned that making a DwC archive the primary exchange format for survey or plot data commits us to a path of losing information from the start, for all but the simplest sampling schemas.

Darwin Core: proposed news terms for expressing sample data
by Éamonn Ó Tuama [GBIF] 21 Aug '14

21 Aug '14

Dear All, GBIF is committed to exploring ways in which the IPT and Darwin Core Archive format can be extended for publishing sample-based data sets. In association with the EU BON project [1], a customised version of the IPT [2] has been deployed to test this using a special type of Darwin Core Archive in which the core is an Event with associated taxon occurrences in an Occurrence extension. The Darwin Core vocabulary already provides a rich set of terms with many relevant for describing sample-based data. Synthesising several sources of input (GBIF organised workshop on sample data, May 2013 [3], discussions on the TDWG mailing list in late 2013; internal discussion among EU BON project partners), five new terms relating to sample data were identified as essential. The complete model including these new terms are fully described with examples in the online document Publishing sample data using the GBIF IPT [4]. As a first step towards ratification, we would like to register the new terms in the DwC Google Code tracker [5] if there are no major objections on this list. The five terms are: 1. quantity: the number or enumeration value of the quantityType (e.g., individuals, biomass, biovolume, BraunBlanquetScale) per samplingUnit or a percentage measure recorded for the sample. 2. quantityType: : the entity being referred to by quantity, e.g., individuals, biomass, %species, scale type. 3. samplingGeometry: an indication of what kind of space was sampled; select from point, line, area or volume. 4. samplingUnit: the unit of measurement used for reporting the quantity in the sample, e.g., minute, hour, day, metre, metre^2, metre^3. It is combined with quantity and quantityType to provide the complete measurement, e.g., 9 individuals per day, 4 biomass-gm per metre^2. 5. eventSeriesID: an identifier for a set of events that are associated in some way, e.g., a monitoring series; may be a global unique identifier or an identifier specific to the series.

Initiation of public comment on proposed Darwin Core changes
by joel sachs 11 Aug '14

11 Aug '14

All, As Steve pointed out [1], the Darwin Core Term Change Policy [2] specifies that a 30-day public comment period is required before significant changes are made to the standard. I always thought that this 30 day period automatically begins when proposed changes are summarized and entered into the Issue Tracker. Steve, however, believes that the public-comment period must be initiated via an email to tdwg-content, sent by either John (in his capacity as DwC steward), or by the executive. Maybe the best reading of the policy is that public comment periods should be initiated via email to tdwg-content, and that anyone can initiate a public comment period for a proposal that is contained in the Issue Tracker. Taking this reading, I hereby initiate public comment on the changes outlined in issues 204 - 226 in the Darwin Core issue tracker [3]. Best to everyone, Joel. 1. http://lists.tdwg.org/pipermail/tdwg-content/2014-July/003277.html 2. http://rs.tdwg.org/dwc/terms/namespace/index.htm#classesofchanges 3. https://code.google.com/p/darwincore/issues/list

Proposed changes to Darwin Core
by joel sachs 25 Jul '14

25 Jul '14

Hi Everyone, I’d like to direct everyone’s attention to issues 204 - 226 in the Darwin Core issue tracker [1]. These issues describe proposed changes to the Darwin Core standard, and were entered back in January in follow up to the Documenting Darwin Core workshop held at TDWG 2013. These proposals reflect what the organizers of that workshop believe to be the consensus that was reached during the workshop’s four sessions in Florence. The background for this is that, for some time, a number of TDWGers have been working towards an applicability statement to provide guidance on expressing Darwin Core data using RDF. In the course of this work, it became apparent that the semantics of Darwin Core itself needed a slight re-think, in order to be usable on the semantic web. The goal was to be backward-compatible, i.e. to introduce and re-define terms in a way that does not affect the meaning of existing Darwin Core spreadsheet data, but which provides the semantic grounding necessary for meaningful RDF. I think this goal has, for the most part, been realized. If you have examples to the contrary, please share them. Steve Baskauf provides a good overview of the proposals in Issue 204. Of all of them, only Issue 205 (the introduction of a class to represent the taxonomically homogenous units that are described in Darwin Core occurrence data) was contentious, primarily because we disagreed on a good name for the class. (“We” refers to the ad-hoc group that worked on translating the notes from the workshop into concrete proposals - John Wieczorek, James Macklin, Markus Döring, Rich Pyle, Tim Robertson, Bob Morris, Hilmar Lapp, Steve Baskauf, Gregor Hagedorn, and myself.) I’ve mentioned my own concerns as a comment on that issue. There is one proposal that had the support of the group, but that is not yet entered into the Issue Tracker - the deprecation of dwc:basisOfRecord. The motivation for this proposal is that dwc:basisOfRecord is widely misunderstood and inconsistently used, coupled with the fact that GBIF currently uses basisOfRecord with the semantics of the (to be proposed) dwc:hasEvidence term. However, we have held back on proposing "hasEvidence", as there remain some unresolved issues regarding how it would be used. This will likely be left as future work, perhaps to be tackled at TDWG 2014. Many thanks to all who participated in the workshop, and to all who take the time to review its outcomes.

You're Invited - Data Management Interest Group - Kickoff Webinar 7 August
by Debbie Paul 20 Jul '14

20 Jul '14

Hello Everyone!, Got data in your database? Have you shared it? Is your data available via one or more other websites? Can you get enhanced, modified, standardized, georeferenced, annotated data from these sites back into your database? Re-integrating data can be challenging for many reasons.

delimiter characters for concatenated IDs
by "Dröge, Gabriele" 06 May '14

06 May '14

Hi everyone, I guess there might have been some discussions about proper delimiter characters in the past that I have missed. In several projects, first of all in GGBN (Global Genome Biodiversity Network, http://www.ggbn.org), there is a need for making a decision now. We need to reference between different records and databases and within Darwin Core we want to use the relatedResourceID to do so. During our GGBN workshop at TDWG last year we agreed on concatenating the traditional triple ID (Catalogue Number, Collection Code, Institution Code) and add further parameters if required too (e.g. GUID, access point). We have checked those parameters and can definitely not use a single character as delimiter. So my question to you is, if there are already some suggestions on using two characters together as delimiters. It would be great if we could find a solution more than one community could agree on. Otherwise I would like to open the discussion and suggest "\\", "||", "\|", "§|", "§§", or "\§".

Re: [tdwg-content] delimiter characters for concatenated IDs
by "Dröge, Gabriele" 06 May '14

Thanks Gregor! I must say I really like this idea for our short term solution! Will discuss this with my team. Best, Gabi Von: Gregor Hagedorn [mailto:gregor.hagedorn@mfn-berlin.de] Gesendet: Dienstag, 6. Mai 2014 13:57 An: Dröge, Gabriele Cc: tdwg-content(a)lists.tdwg.org Betreff: Re: [tdwg-content] delimiter characters for concatenated IDs On the original question: my preference when creating an identifier for the triplet would be to be transparent, and create the identifer with the dwc terms embedded, i.e. use institutionCode=BGBM&collectionCode=xxx&catalogNumber=289742874239872 as the "self-coined" identifier string. While "&" may not be unique, the delimiter &collectionCode= is very likely so. And it is transparent, self-documenting what is going on (and I do not mean that people need to parse it - which they could in either case) Gregor On 5 May 2014 15:24, "Dröge, Gabriele" <g.droege(a)bgbm.org<mailto:g.droege@bgbm.org>> wrote: Hi everyone, I guess there might have been some discussions about proper delimiter characters in the past that I have missed.
