"the [controlled] vocabularies can be quite dynamic, variable, and/or contentious"
Indeed they can. But, avoiding them I think is not the solution for the community. Avoiding them proliferates even more dynamics, variability and contention. However, the standardization of controlled vocabularies needs to be a separate activity, one that TDWG has been somewhat absent from of late and one we need to add to the mix of issues for TDWG to address. I suspect there is a lot of programming time being spent on discovering the dynamics and variability of the vocabularies currently in use and remediating them repeatedly in separate and far corners of the world. Even some small effort to consolidate a few variations or at least sort them out once rather than repeatedly by every new programmer that comes into this community would be beneficial to the biodiversity informatics world.

1 comment - I feel a little uncomfortable about the unstructured

I understand your discomfort. That proposed term is to take the place of the corresponding associatedOccurrences. As with the other "associatedX" terms, it is meant to allow useful information to be retained as part of flat records, not necessarily to be rigorously interpretable for the contents of the list, which would require data content standards as well.
There is possibly a few ways to improve this:
- define a structured way of filling this field, eg "[relationship
type (from controlled vocabulary), eg host]:[related Organism ID]"
- add another field for just associatedOrganismIDs, that just has the
IDs and not free form text - not sure how this will help though
- add another class for AssociatedOrganism, that has fromOrganismID,
toOrganismID and relationshipType
This is really the realm of more relational representations, in which you could use the ResourceRelationship class to good effect.
I also notice with a few of the DwC terms that it is recommended to
use a controlled vocabulary for setting the value of the term, but the controlled vocabulary itself is not provided. Is it not the place for the DwC vocabulary to provide these? Or has the work just not been done to define them?
No Darwin Core term enforces controlled vocabularies. Only recommendations are made, and that's on purpose. One of the biggest reasons is that the vocabularies can be quite dynamic, variable, and/or contentious, and we did not want that distraction in the management of the Darwin Core terms.

Dear all,
Prepare yourself mentally. After more than a year of discussions,
prototypes, scholarly papers, bar room brawls, etc., we are very near having a path forward for two new, related classes for Darwin Core that attempt to remove ambiguity inherent in the Occurrence class as it currently stands. Adding classes is quite a bit more complicated than adding properties (as you'll see if you manage to get through this message), and so it is important to be as thorough as possible to make sure we get it right. I'll try here to synthesize the rough consensus and the remaining issues.
Basically, the idea is to pull two distinct concepts out of Occurrence
and give them their own classes.
Maybe not surprisingly, one of the hardest things to agree upon has
been the names for these classes. The class that was proposed first as "Individual" has seen no less than 12 alternate names, none of them satisfying to everyone. The closest thing to an acceptable name was "Organism", with caveats that the definition should make it abundantly clear what is to be included in the class and what is not. I'll use "Organism" here to refer to the class in the hopes of offending the fewest people.
The rough consensus on "Organism" is that is should include viruses,
symbionts, individuals, colonies, groups of individuals, and even populations, but that there should be taxonomic homogeneity to an instance of an "Organism". There has been some concern about how and where to draw the line on homogeneity. No attempt has yet been made to write a definitive description of the class, though many examples of representatives of the class have been given.
What we need to move forward on the "Organism" class are an official
definition and an official comment, the combination of which should be sufficient for someone previously unfamiliar with the term and the arguments leading to its existence to understand. Some existing terms (individualCount, sex, lifeStage, reproductiveCondition, behavior, previousIdentifications, associatedTaxa) will have to be reorganized to be under this new class. These terms may require updated definitions for consistency. New terms (organismID, associatedOrganisms, organismRemarks) and an Organism Darwin Core Type vocabulary term will have to be added. Following is an updated proposal for changes related to the adoption of a new "Organism"
class:
Term Name: Organism Identifier: http://rs.tdwg.org/dwc/terms/Organism Namespace: http://rs.tdwg.org/dwc/terms/ Label: Organism Definition: The category of information pertaining to a specific instance of an organism (virus, symbiont, individual, colony, group of
individuals, population) reliably be known to taxonomically homogeneous.

The class proposed as "CollectionObject" has seen fewer alternate name
proposals than "Organism", but the same call for clarity on inclusion and exclusion has been voiced. The basic idea is to use this class to cover information that could be considered "persistent evidence" that an organism occurred, and that the concept is distinct from both "Organism" and Occurrence. Evidence might include collection-based materials, digital media, written materials, and literature.
"Evidence" may be a bit vague as a name for the class, providing no
real indication that the "Evidence" should apply to an "Organism"
rather than to an Occurrence, Taxon, Identification, or any other
class. Nor does it convey the idea that the evidence should be persistent. "PersistentEvidenceThatAnOrganismExisted" gets the idea across pretty well, but it is a bit lengthy (and no one actually proposed this name). ABCD isn't shy about vague term names - it uses "Unit" for roughly this concept. The long-standing term "CollectionObject" is less vague than the proposed alternatives, but it might lead people to assume that the object must be physical, and that it must be housed within a collection, neither of which is strictly required. No one objected to this name for the term, however, so I will continue to use it here to illustrate the proposed changes and additions to accommodate this concept.
Some existing terms (institutionID, institutionCode, collectionID,
collectionCode, ownerInstitutionCode, catalogNumber, preparations, disposition, otherCatalogNumbers, associatedSequences) will have to be organized under this new class. These terms may require updated definitions for consistency. Note that with the addition of the "CollectionObject" class, the institutionCode, collectionCode, catalogNumber triplet would no longer apply to an Occurrence.
New terms (collectionObjectID and collectionObjectRemarks) and an
CollectionObject Darwin Core Type vocabulary term will have to be added. Following is an updated proposal for changes related to the adoption of a new "CollectionObject" class:
Term Name: CollectionObject Identifier: http://rs.tdwg.org/dwc/terms/CollectionObject Namespace: http://rs.tdwg.org/dwc/terms/ Label: CollectionObject Definition: The category of information pertaining to persistent evidence that an organism existed (specimen, sample, image, sound,
drawing, field notes, publication), including digital forms.

Because of these changes for "Organism" and "CollectionObject", the
definition of the Occurrence class will have to change and quite a different set of terms organized under it, namely:
occurrenceID, occurrenceRemarks, recordNumber, recordedBy, establishmentMeans, and occurrenceStatus
The Occurrence definition will change from "The category of
information pertaining to evidence of an occurrence in nature, in a collection, or in a dataset (specimen, observation, etc.)." to something more akin to "The category of information pertaining to evidence of an occurrence of an Organism in nature."
The term occurrenceDetails will be deprecated in favor of the Dublin
Core term dcterms:references at the record level. Also, associatedMedia, which was organized under Occurrence, would become a record level term, as it could apply as easily to Occurrences, "Organisms", and "CollectionObjects".
If you made it this far, I congratulate you on your dedication to the
cause. Please let's clear up the remaining issues as a community and put these new terms to good use.
Cheers,
John _______________________________________________ tdwg-content mailing list tdwg-content@lists.tdwg.org http://lists.tdwg.org/mailman/listinfo/tdwg-content

Hi Chuck,
+1 from me. I agree that we need to have controlled vocabularies, and I also agree that this could/should be an activity separate from defining the terms themselves. The only problem I forsee is how to link a controlled vocabulary list with a DWC term without bringing some of that contention into the discussion for the term.
Cheers, Ben

collectionCode, ownerInstitutionCode, catalogNumber, preparations, disposition, otherCatalogNumbers, associatedSequences) will have to be organized under this new class. These terms may require updated definitions for consistency. Note that with the addition of the "CollectionObject" class, the institutionCode, collectionCode, catalogNumber triplet would no longer apply to an Occurrence.
New terms (collectionObjectID and collectionObjectRemarks) and an
CollectionObject Darwin Core Type vocabulary term will have to be added. Following is an updated proposal for changes related to the adoption of a new "CollectionObject" class:
Term Name: CollectionObject Identifier: http://rs.tdwg.org/dwc/terms/CollectionObject Namespace: http://rs.tdwg.org/dwc/terms/ Label: CollectionObject Definition: The category of information pertaining to persistent evidence that an organism existed (specimen, sample, image, sound,
drawing, field notes, publication), including digital forms.

Term Name: collectionObjectID Identifier: http://rs.tdwg.org/dwc/terms/collectionObjectID Namespace: http://rs.tdwg.org/dwc/terms/ Label: collectionObjectID Definition: An identifier for the CollectionObject. In the absence of a persistent global unique identifier, construct one from a
combination of identifiers in the record that will most closely make the collectionObjectID globally unique.
Comment: For a specimen in the absence of a bona fide global unique identifier, for example, use the form: "urn:catalog:[institutionCode]:[collectionCode]:[catalogNumber]. Examples: "urn:lsid:nhm.ku.edu:Herps:32", "urn:catalog:FMNH:Mammal:145732".

Because of these changes for "Organism" and "CollectionObject", the
definition of the Occurrence class will have to change and quite a different set of terms organized under it, namely:
occurrenceID, occurrenceRemarks, recordNumber, recordedBy, establishmentMeans, and occurrenceStatus
The Occurrence definition will change from "The category of
information pertaining to evidence of an occurrence in nature, in a collection, or in a dataset (specimen, observation, etc.)." to something more akin to "The category of information pertaining to evidence of an occurrence of an Organism in nature."
The term occurrenceDetails will be deprecated in favor of the Dublin
Core term dcterms:references at the record level. Also, associatedMedia, which was organized under Occurrence, would become a record level term, as it could apply as easily to Occurrences, "Organisms", and "CollectionObjects".
If you made it this far, I congratulate you on your dedication to the
cause. Please let's clear up the remaining issues as a community and put these new terms to good use.
Cheers,
John _______________________________________________ tdwg-content mailing list tdwg-content@lists.tdwg.org http://lists.tdwg.org/mailman/listinfo/tdwg-content
