This proposal is under active development in the 'OSR - How Did It Die?' Task Group.

  • Submitter: Sophia Ratcliffe - NBN Trust (https://nbnatlas.org/)
  • Proponents (at least two independent parties who need this term): I have had requests from several of our data providers asking for the ability to supply and filter records by alive/dead status
  • Justification (why is this term necessary?): We receive many records where the occurrence was of a dead animal and at the moment there is no way store the status of the organism in a DwC term with a controlled vocabulary. It is really important in marine records, which often contain stranding information, and for road kill records.

Proposed definition of the new term:

  • Term name (in lowerCamelCase): organismStatus
  • Class (e.g. Location, Taxon): organism
  • Definition of the term: A description of the status of the organism (alive or dead)
  • Comment (examples, recommendations regarding content, etc.): Recommended best practice is to use a controlled vocabulary, with the terms alive, dead, unknown
  • Refines (identifier of the broader term this term refines, if applicable): Currently we've been using occurrenceRemarks, but it is not easily searchable.
  • Replaces (identifier of the existing term that would be deprecated and replaced by this term, if applicable): N/A
  • ABCD 2.06 (XPATH of the equivalent term in ABCD, if applicable): N/A

I support the concept, but not so much the suggested name. Status can mean so many things. Can't think of a better one yet.

Also, there is the issue of dead museum specimens and living culture collections. I'm not certain these matter if they are described as dead or alive, as long as it is appropriate, but it is worth considering. I think basisOfRecord is currently used for some of these distinctions.

Yes, I didn't like using status, but it felt consistent with other DwC terms.

The new term would be used for field observations where the basisOfRecord is HumanObservation (or Occurrence, as some data providers use).

A possible name could use vitality.

Or viability, which is already used for seed collections (values might be viable, dormant, inviable, dead)

Could the definition be changed to

An indication of whether the organism was alive or dead at the time of collection or observation.

Comment: Generally Intended to be used with a dwc:basisOfRecord of PreservedSpecimen, MaterialSample, or HumanObservation.

A further thought

If this field is added to Darwin Core then next obvious need would be causeOfDeath.

Rather than just having a flag to say if something is dead, why not jump straight to a causeOfDeath field with a vocabulary?

@sophiathirza
Copy link
Author

causeOfDeath would be really useful, then we can differentiate strandings, road kills etc.

A single term for vitality, with @qgroom's suggestion for the definition and comment, would still be useful, so that we can easily select all 'dead' records, but if needs be, we can derive that from causeOfDeath.

qgroom commented May 30, 2019

I don't like boolean flag fields in the standard when they can be derived from other fields. This doesn't mean they can't be implemented in a database to make searching faster, but as long as they are always derived from one source field there is no danger of a mismatch, where for example one vitality says living, but the cause of death is roadkill.

It is a good question for GBIF though. @MattBlissett was saying dwc:year is derived from dwc:eventdate if it is empty. How much is GBIF willing to add non-standard fields for indexing if they are derived from standard fields?

Potential user here: we work on wild ungulates, and would be interested in vitality and causeOfDeath terms.

Some of our data is road kill data (individual observed dead, with an obvious cause), hunting data (dead animals, through various types of hunting methods), monitoring data (live animals / animals found dead).

The executive of TDWG thinks this is an important issue to consider. The first step would be to engage in discussion with the Darwin Core Maintenance Group to figure out the next steps.

@tucotuco @peterdesmet @mdoering @timrobertson100 @baskaufs @pzermoglio @morr @chicoreus

Consideration by the Darwin Core Maintenance Group should include whether development of this term and a controlled vocabulary of values for it (including the development of user stories and competency questions) would fall within the scope of the maintenance group, or whether this work is of sufficient scope to merit a new task group.

Consideration also needs to be paid to alignment with ABCD, including the PaleontologicalUnit/Preservation/Taphonomy and PaleontologicalUnit/Preservation/Completeness terms.

@baskaufs
Copy link

It seems to me that this term should be organized under the Occurrence class rather than Organism. In the thread, we've been talking about the status of the organism at the time when it was observed or collected. That makes it specific to a particular Occurrence of the organism, since an organism can be observed repeatedly and on some of those Occurrences it might have been alive, then dead on its last occurrence (perhaps being made to be dead by the collection).

@baskaufs Agree. Changed label.

I very much like the term vitality and we should probably think about a short accompanying vocabulary that is more expressive than just the binary dead or alive.

Would you also use it for exuviae or shells?
I found a slide from 2014 about establishmentMeans and its actual content in GBIF which contained a few indications to dead organisms. It seems causeOfDeath is a good company for vitality:

Is it still possible to contribute to this conversation related to OccurrenceStatus. Currently there are 2 terms: present or absent. if an animal/plant is dead it is still present. I would like to propose the addition of a new term called 'trace'. This term could be assigned to observations of shells - these animals should not be flagged as present/dead if the shell is empty. a crab shell can be considered present/dead but an empty snail shell should be flagged as 'trace'.
Other cases where 'trace' could be assigned are when one observes scat, tracks, nests, etc. In these cases there are 'traces' that an animal was present at this location at some time in the past. the animal is not present at the time that the observation was made. It does not imply that the animal is dead.

It hasn't progressed further than agreeing to set up a task group to explain the rationale of adding new terms for vitality and cause of death and their vocabularies. I've started the charter and meant to send it round to very one for comment. Let me know if you're interested in being involved. Thanks.

@sophiathirza that's fantastic! I guess it would be easiest to share it here, but at some point soon we should transition off this issue thread.
Once there is an official task group there can be a TDWG repository for the group to share thoughts and documents.

@tucotuco I think it would be appropriate that the Task Group be under the Observations & Specimens Interest Group, as @qgroom suggests. I don't think the Darwin Core Maintenance group should be dealing with this. In cases where new terms (or changes to existing terms) are needed that deal with specific necessities of the community, task groups that are specific to those needs should be under interest groups that are also specific (although less so) to those needs. Maybe in this case is not so obvious, but suppose some other case where paleo terms were needed. One should not expect the DwC MG -or task group within it- to deal with building those terms, their definitions, etc., but rather have the expert groups do it, and come to the DwC MG with a solid, full proposal, for incorporation of new/changed terms.
To put it more briefly, I envision experts in expert groups, and the DwC MG in more of a maintenance/overseeing role. Communication between the groups would of course be of capital importance to the whole process. Also, probably the charter should include a particular task to have the terms ratified in Darwin Core.

As for what the Vocabulary Maintenance Specification says, it could actually happen both ways:

2.1 [...] In the case where a new vocabulary is related to an existing vocabulary having an existing maintaining Interest Group, maintenance of the new vocabulary may be assigned to the existing Interest Group. [...]

2.2 The vocabulary maintenance Interest Group may also establish Task Groups to accomplish broader changes to the standard, such as creating or revising associated documents, or determining how the terms of the vocabulary might be used with a new technology.

@baskaufs Thoughts?

@baskaufs

My initial thought was that @tucotuco was correct, particularly since the charter describes the creation of two new Darwin Core terms, and that would clearly be the responsibility of the DwC Maintenance Group to shepherd.

However, upon further reflection, I was thinking about the spirit behind section 4 of the VMS. Section 4 describes the development of "vocabulary enhancements". Vocabulary enhancements are defined in section 1.4 and development of controlled vocabularies does not fall within their definition. But the rationale behind section 4 is that when a set of coordinated additions to a vocabulary become complex, it is best to consider them a package that has a higher standard for development and testing than would be necessary for the adoption of a single term. In that situation, the best practice is to document the rationale and implementation testing through the two types of user feedback reports described in section 4.

In Audubon Core, we are currently working three coordinated sets of additions to the standard (a set of terms related to 3D, controlled vocabularies for ac:subjectPart and ac:subjectOrientation, and a set of terms related to sound). Two of these sets of additions have associated task groups chartered under the MG and one does not. But given that they are complex coordinated additions, as AC MG convener, I'm requesting a Feature Report and Implementation Experience Report for all three proposals. The point of those reports is to streamline the adoption process by making it clear during the public comment period and Executive Decision what the proposal is supposed to accomplish and that it actually can accomplish what was proposed.

The last paragraph is somewhat tangential to the question at hand, but the point of section 4 of the VMS is about how to effectively implement changes to a standard that are more complicated than a single term addition. Section 4 specifically allows vocabulary enhancements to be proposed by groups that are NOT task groups chartered by the maintenance group in order to enable those who take initiative and do the work to succeed in improving TDWG vocabularies regardless of whether the maintenance group asked them to do it or not. Given that spirit, if chartering this proposed Task Group under an interest group other than the DwC Maintenance Group is the most effective way to get a good proposal, then I wouldn't oppose that.

The one thing that concerns me a bit about not chartering the Task Group under the Darwin Core MG is wondering how the task group would relate to the Observations and Specimens Group and to the DwC Maintenance Group. The last paragraph of section 4.1 of the VMG describes a back and forth process between the vocabulary MG and the group developing the enhancement, where the MG evaluates how the proposal will fit in with the operation of the existing vocabulary and gives feedback to the TG if it does not think the proposal is ready. The MG essentially acts as the gatekeeper to determine when the proposal is mature enough to advance to public comment. (In this case, the MG is acting in the role that would be assumed by a Review Manager for a new standard.) I'm assuming that if the Observations and Specimens Group Interest group charters this task group, the DwC MG would still operate in this gatekeeper role and that the O&S group would just act in an advisory role for the development of a better proposal. But I think it would be good to be clear about this from the start since we would be potentially creating a gray area if the Task Group is not clear about what their relationship is with the O&S "parent" interest group.

Thanks @pzermoglio and @baskaufs. I see what Paula is saying and it makes sense to me, particularly if/since ABCD could benefit from the work as well, and the two standards intend to work toward each other. I had the same concern about interaction with the DwC MG and hoped that something concrete could be in the TG charter about that. I fully support what Steve mentions about how to accomplish that.

I have put all the information into the GitHub repository (https://github.com/tdwg/how-did-it-die) and it is now open for your contributions and discussions.

The repository is organised following the Collection Descriptions Interest Group (https://github.com/tdwg/cd) repository, hopefully it's clear but do suggest changes if you think something could be improved.

The proposed new properties (one to the core standard and four in a new extension) have separate issues to comment on the name, definition etc: https://github.com/tdwg/how-did-it-die/issues and I've created an issue for each new controlled vocabulary: https://github.com/tdwg/how-did-it-die/issues?q=is%3Aissue+is%3Aopen+label%3Avocabulary linked to a google document to add suggestions. The idea was to keep the vocabulary discussion separate from more general details of the property.

What we need now is:

  • agreement on the new properties (name, definition, whether core or extension)
  • suggestions for controlled vocabulary terms including definitions
  • uses cases to support the new properties and controlled vocabulary terms

Please add use cases as individual issues (https://github.com/tdwg/how-did-it-die/issues); I've added one for the roadkill term to get started: https://github.com/tdwg/how-did-it-die/labels/use%20case. I will move the use cases to the folder in the repository (https://github.com/tdwg/how-did-it-die/tree/main/use_cases) once we've agreed which use cases to include. There is some holding text in the folder for now.

I will arrange a meeting for early May to review the feedback and suggestions and decide how we can start writing it all up. Please let me know if you would like to join the call and what time zone you are in. We may need two calls.

I will write to all the attendees of the working session in TDWG 2020, apologies if you get this twice.
