Dear Daniela: The Biological Collections Ontology (BCO) <https://github.com/tucotuco/bco> maps Darwin Core terms to an ontology. One of our goals for doing this is so that we can work out the semantics of new terms requests before they are submitted to Darwin Core, thereby, we hope, avoiding circular and often hard to follow discussions on the mailing list. The process we suggest is to explore the definitions and semantics of terms in BCO, and then, once there is some agreement, request them to DwC if appropriate. In many case, new terms may not be needed for Darwin Core, but instead we can provide a controlled vocabulary to serve as the values for existing Darwin Core properties. We have a recent request for origin and establishment terms ( https://github.com/tucotuco/bco/issues/30), which we have begun working on. I think that your request for domestication status fits very nicely with this, and we could include terms as part of the same discussion. Would you be willing to add your comments and suggested definitions to the issue? Ramona ------------------------------------------------------ Ramona L.

Dear Daniela, I understand the value and interest of what you are seeking to achieve. However, it is a little more complicated. The Darwin Core data that you see in GBIF is from data shared by many different publishers from work on their collections or field research. Few of these data sets standardly mark all records e.g. as "alien" or "naturalised" or "domesticated" - because it is not necessarily a significant factor in the context of their research. For this reason, marking data which relates to "domesticated" organisms or "wild relatives" can only easily be handled as a secondary interpretation of the data. This would be possible if we had an agreed list of species which should be tagged this way. It may however be that the tags should only apply in certain localities, since the species may exist in the wild in other areas. This introduces more complexity. For this reason, right now, it makes most sense for researchers to identify the list of species of interest to them and the areas of interest and filter data accordingly. If you are able to identify a suitable and generally useful list of species that could be of value to others, we can explore ways to make it accessible and to use it to tag the species in question. Sorry if this is not a quick answer, but I hope it helps.

Notes on the Biological Collections Ontology
by Quentin Groom 27 Mar '15

27 Mar '15

Dear All, To acquaint myself with the Biological Collections Ontology I went through it and made some notes. John Wieczorek suggested I share these notes so that they can be responded to openly. They are as follows, I look forward to your comments. 1. Why are the dates clustered together in one branch, but day, month, year separate? 2. eventDate: regarding date ranges. Sometimes an event continues for a period such as a field trip, but often a date range is required because although the event took place in a certain time frame, the exact event date is not known. There should perhaps be a way of distinguishing between these two situations. 3. Vernacular name should be associated with a language and a geographic area where it is used? 4. verbatimSRS, footprintSRS and geodeticDatum are similar but not the same. They seem to overlap. The SRS has a clear definition epsg- registry.org, but geodeticDatum is a more general term. The definitions and usages could be stronger. 5. There is a need for local grid reference systems. Many countries have their own ways of writing grid references and verbatimLongitude and verbatimLatitude are not suitable for these. For example, the UK has grid references such as NZ28F, which mean something very specific in the country. It is a similar situation in Belgium and I imagine other countries. 6. georeferenceVerificationStatus & identificationVerificationStatus: It is not clear how these should be used. The names are similar, but the described usage is very different. I find it hard to imagine how they would be used in practice. 7. There are occasions within biogeographic databases where you want to indicate that an observation or collection is not trusted. I can’t see a place where a record can be verified as a whole. For example, if it is suspected that the label has been muddled up or the collector is suspected of fraud. With an observation there is no specimen to verify, but the record should be verifiable. 8. member, lithostratigraphicTerms, bed etc etc. I don’t know anything about geology, but these terms seem to overlap and could perhaps be thought of as synonymous. It would be valuable to find records where these terms are required to see how they are used in practice. 9. county & stateProvince: These are parochial terms. There are many nested subdivisions of countries and there is probably a better way to describe them. Perhaps there is already a hierarchical ontology to describe geographic areas. 10. Abundance estimates: There are several ways to describe estimates of abundance, such as DOMAIN, DAFOR, percent coverage, is there a way to accommodate these? 11. Controlled vocabularies: Many terms suggest using a controlled vocabulary, but most don’t have one. Is this an area we should work on? 12. Consider the importance of citation and providence the “according to” information seems rather weak. There should perhaps be a space for an identifier (ORCID). Also, biographic information such as date of birth, date of death, institutional association. These are useful for providence, but also for validation of records. 13. What is the difference between fieldNumber and recordNumber? 14. establishmentMeans: the description seems to conflate three concepts, the length a taxon has been established at a location (e.g. native); the way it got to the location (e.g. introduced) and the dispersive ability of the taxon (e.g. invasive). To my mind the latter is not required as it is an opinion about the taxon as a whole not the observation. The first two should be separated to make them useful. People need to distinguish between the native status of a species at a location and how it got to that location. Invasive species biologists are particularly interested in the vectors of introduction. 15. The health of an animal or plant can be noted on an observation and is useful for analysis. Is there some way of stating that the organism was dead when the specimen or observation was made?

Darwin Core terms sex and lifeStage with mixed content
by John Wieczorek 26 Mar '15

26 Mar '15

Dear all, There is a body of topics surrounding Darwin Core terms for which it is tempting to overload the content in an effort to provide richer data than the standard would seem to support. We have a pair of older open issues on this general topic in the Darwin Core issue tracker. https://github.com/tdwg/dwc/issues/35 https://github.com/tdwg/dwc/issues/36 You can see in the discussions on those issues that there is some consensus that the content of Darwin Core terms should remain consistent with the definitions and not mix concepts. I've had recent questions in particular about the fields 'sex' and 'individualCount'. Here is an example. How should one populate Darwin Core terms for a record of 2 males and 5 females in a single lot? I propose that part of this is easy - the individualCount should be 7. The definition of the sex term (without looking for clues in the Comments) might be seen as a little ambiguous, "The sex of the biological individual(s) represented in the Occurrence. Recommended best practice is to use a controlled vocabulary." Strictly speaking, there is no single sex that matches the biological individuals in this example lot Occurrence record, and so the sex fields should be left blank. There are a number of terms in Darwin Core whose definitions suggest that a list (formatted with ' | ' as a separator) be used to match multiple values. Though it might seem that sex could be one of these terms, it isn't currently. Again this argues for a single value for sex from a controlled vocabulary. The biggest problem is with the Comment on the sex term, which gives an example with different semantics from what the definition says - namely "8 males, 4 females". I pose that this is an error and must be corrected. Yet, all hope of retaining information in the Occurrence record is not lost. To capture the richness of the information in the multi-sex lot example, I would recommend the use of dynamicProperties. How should one populate Darwin Core terms for a record of 2 males and 5 females in a single lot? I would do this: sex = null individualCount = 7 dynamicProperties= { "count of males":2, "count of females":5 } Hope that makes sense. Since this topic has arisen from multiple independent sources, I would like to formally propose changes to the sex and lifeStage terms to remove the spurious examples. Today begins a minimum 30-day public commentary period to close on 5 March 2015 if no dissenting opinions are made in this public forum. Here is how the new terms would appear if the changes are accepted: Identifier: http://rs.tdwg.org/dwc/terms/sex Namespace: http://rs.tdwg.org/dwc/terms/ Label: Sex Definition: The sex of the biological individual(s) represented in the Occurrence. Recommended best practice is to use a controlled vocabulary. Comment: Examples: "female", "hermaphrodite", "male".

Re: [tdwg-content] Darwin Core Proposal - term content recommendations to comments
by Ramona Walls 23 Mar '15

This is a good idea. In theory the recommendation could go into a separate annotation (e.g., we use "example of usage" in BCO), but I don't think that is necessary for DwC at this juncture.

Darwin Core Proposal - sampling event terms
by John Wieczorek 20 Mar '15

20 Mar '15

Dear all, I am following up with the proposal for sampling event terms that have been discussed earlier in this forum in a few threads [1,2,3]. Below is the final proposal for five new terms as it stands ready to be presented to the Executive Committee for ratification after taking into account the commentaries to date. As this summary consists of no semantic changes over what has been discussed already, the proposal should be ready for presentation on 23 Jan 2015, barring any expressed objections to the current proposal. Term Name: parentEventID Identifier: http://rs.tdwg.org/dwc/terms/parentEventID Namespace: http://rs.tdwg.org/dwc/terms Label: Parent Event ID Definition: An identifier for the broader Event that groups this and potentially other Events. Comment: May be a globally unique identifier or an identifier specific to the data set. Example: “A1” as parentEventID to identify the main Whittaker Plot in nested samples, each with its own eventID (e.g., “A1:1”, “A1:2”). For discussion see http://terms.tdwg.org/wiki/dwc:parentEventID. Type of Term: http://www.w3.org/1999/02/22-rdf-syntax-ns#Property Refines: Status: proposed Date Issued: 2014-11-07 Date Modified: 2014-12-23 Has Domain: Has Range: Version: parentEventID-2014-12-23 Replaces: IsReplaceBy: Class: http://rs.tdwg.org/dwc/terms/Event ABCD 2.0.6: not in ABCD Issue reference: https://github.com/tdwg/dwc/issues/9 Term Name: sampleSizeValue Identifier: http://rs.tdwg.org/dwc/terms/sampleSizeValue Namespace: http://rs.tdwg.org/dwc/terms Label: Sample Size Value Definition: A numeric value for a measurement of the size (time duration, length, area, or volume) of a sample in a sampling event. Comment: A sampleSizeValue must have a corresponding sampleSizeUnit. Example: “5" for sampleSizeValue with "metre” for sampleSizeUnit. For discussion see http://terms.tdwg.org/wiki/dwc:sampleSizeUnit. Type of Term: http://www.w3.org/1999/02/22-rdf-syntax-ns#Property Refines: Status: proposed Date Issued: 2014-11-07 Date Modified: 2014-12-23 Has Domain: Has Range: Version: sampleSizeValue-2014-12-23 Replaces: IsReplaceBy: Class: http://rs.tdwg.org/dwc/terms/Event ABCD 2.0.6: not in ABCD Issue reference: https://github.com/tdwg/dwc/issues/10 Term Name: sampleSizeUnit Identifier: http://rs.tdwg.org/dwc/terms/sampleSizeUnit Namespace: http://rs.tdwg.org/dwc/terms Label: Sample Size Unit Definition: The unit of measurement of the size (time duration, length, area, or volume) of a sample in a sampling event. Comment: A sampleSizeUnit must have a corresponding sampleSizeValue, e.g., “5" for sampleSizeValue with "metre” for sampleSizeUnit. Examples: “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/ of SI units, derived units, or other non-SI units accepted for use within the SI (e.g., minute, hour, day, litre).

Comment: An organismQuantity must have a corresponding organismQuantityType, e.g., “27” for organismQuantity with “individuals” for organismQuantityType; “12.5” for organismQuantity with “%biomass” for organismQuantityType; “r” for organismQuantity with “BraunBlanquetScale” for organismQuantityType.

Fwd: [dwc] quantity (#12)
by John Wieczorek 05 Mar '15

05 Mar '15

Der all, I am forwarding this comment from Simon Cox, which was submitted to the Darwin Core development site on Github. Cheers, John ---------- Forwarded message ---------- From: Simon Cox <notifications(a)github.com> Date: Mon, Dec 15, 2014 at 4:47 AM Subject: Re: [dwc] quantity (#12) To: tdwg/dwc <dwc(a)noreply.github.com> Cc: John Wieczorek <tuco(a)berkeley.edu> 'quantity' usually implies an amount, encoded as a scaled number. In most other domains it does not include a value from an enumerated set. The latter may be called 'quality'. Both quantity and quality are subclasses of 'property'. — Reply to this email directly or view it on GitHub <https://github.com/tdwg/dwc/issues/12#issuecomment-66946784>.

Best practice for scientificNameAuthorship?
by Andréa Matsunaga 25 Feb '15

25 Feb '15

Dear experts. What is the best practice for the DwC scientificNameAuthorship when there is a specific epithet author as well as infraspecific epithet author in a scientific name? Both names concatenated by some character? Only the infraspecific epithet author? Both pieces of information would go into DwC scientificname, but I'm looking for how users would use scientificNameAuthorship and what is useful to have there. Thank you, --am
