http://rs.tdwg.org/dwc/terms/index.htm#associatedOccurrences carries this description: associatedOccurrences Identifier: http://rs.tdwg.org/dwc/terms/associatedOccurrences Class: http://rs.tdwg.org/dwc/terms/Occurrence Definition: A list (concatenated and separated) of identifiers of other Occurrence records and their associations to this Occurrence. Comment: Example: "sibling of FMNH:Mammal:1234; sibling of FMNH:Mammal:1235". For discussion see http://code.google.com/p/darwincore/wiki/Occurrence Details: associatedOccurrences My questions: a. Are the names of the associations, and/or the syntax of the value meant to be community defined? b. If no to a. , where are those definitions? If yes, Have any communities defined any names and syntax? I am especially interested in "duplicate of" in the case of herbarium sheets." c. (May share an answer with b.) Is there any use being made by anyone in which associatedOccurrences is designed to have machine-readable values. If yes, where? Thanks Bob -- Robert A.

Replying to all doesn't
by Mark Wilden 24 Aug '10

24 Aug '10

It seems incorrect to me that doing "Reply to all" on this list doesn't actually reply to all (i.e., the list). The only way I see to actually "reply to all" is to remember to manually edit the To: line to put in tdwg-content. Granted, inadvertent "replies to all" when just "reply" was intended can be annoying and even embarrassing. However, it does seem that if you explicitly "reply to all," you should do just that. ///ark Web Applications Developer Center for Applied Biodiversity Informatics California Academy of Sciences

That makes sense for expressing "duplicate of" in a machine-readable way, but what about other associations? For example, Is there a definition somewhere for "reminds me of" or "kinda like"? ///ark Web Applications Developer Center for Applied Biodiversity Informatics California Academy of Sciences

Dear all, This year at the TDWG meeting there will be a session on Hardware and Infrastructure. In preparation for that I am interested to know from the community at large if there are particular questions or concerns about public cloud computing solutions such as Amazon Web Services, AppScale, and Google AppEngine.

Re: [tdwg-content] [tdwg-tag] time and space namespaces in Darwin Core
by Bob Morris 12 Aug '10

FWIW, timestamps extracted from EXIF data that a camera put there are typically no more than +- 12 hours accurate, because most devices don't record and/or stamp the timezone. My Android X seems to, but my Canon PowerShot SD750 does not. Your extractions are going to need to add it based on your knowledge about the timezone at the time and location of the bioblitz. Alas, it gets worse, because many people fail to reset their cameras or phones to the local time. To make any kind of educated guess about what time the timestamp \actually/ represents may require knowledge of the device capabilities, what the timezone is where the picture was taken and what it was in the timezone the device thinks its in. The latter might be knowable from specs of the device, e.g. if it can be discovered from those specs that the camera knows its time from a network it is connected to, and if you can deterimine that it actually was connected. But for consumer cameras, this is probably hopeless, and you need metadata from the camera owner. Curiously, the errors from this are not a range, but an enumeration, because timezones worldwide differ from one another by an integral multiple of 1/2 hour. Field biologists of my acquaintance simply keep their cameras always set at GMT. Then at least they know that all their pictures have comparable times. For the bioblitz, participants might consider agreeing to set the cameras to a common time. Aside from the accuracy of hand setting the current time, you would then mainly face social problems about the accuracy of the time: (a) can and will the participants actually do this with the devices they carry; (b)how much will they curse the bioblitz when they forget to set the timezone back to what they intend and (c) do they care whether a picture they took of a pollinator in Massachusetts apparently at high noon, actually was taken in Massachusetts at a time corresponding to high noon in Berlin. At the very least you probably should ask each contributor to record the time on their camera at specified local time each day. All accuracy assertions are about fitness for use. It's not the case that data without accuracy assertions are unfit for any use whatsover. This is because scientific statements are always qualified by either "to the best of current knowledge" or "if we accept the model X into which we put the data". For example, a taxonomic determination may or not be location dependent to the best of current knowledge. For those which aren't, and for the use case "taxonomic determination", geo accuracy is irrelevant. To the best of current knowledge.

Proposed Darwin Core term additions and changes: individualRemarks and establishmentMeans
by Steve Baskauf 11 Aug '10

11 Aug '10

In http://code.google.com/p/darwincore/issues/detail?id=70 I proposed addition of the class Individual to Darwin Core. In the discussion of that proposal, the question was raised as to which existing DwC terms should be a part of this class if it were added. After considerable thought and some work in developing RDF representations for Individuals, I believe that the term establishmentMeans should be a member of the proposed class. It has also become clear to me that if the class is introduced, there is a need for the term individualRemarks which would serve a parallel purpose to other xxRemarks terms in DwC. I have provided implementation examples in the recommendations, which can be found at http://code.google.com/p/darwincore/issues/detail?id=80 and http://code.google.com/p/darwincore/issues/detail?id=81 If you would like to discuss these proposals, please post on the tdwg-contents list or add comments to the Google Code wiki. I have cross-posted to the tdwg-tag list, but I think any discussion would be better held on the tdwg-content list, so please post there. Steve Baskauf -- Steven J.

Latest DwC as TAPIR output model?
by Tim Robertson (GBIF) 10 Aug '10

10 Aug '10

Hi all, This thread started as a query about the availability of the latest DwC in TAPIR output models, and specifically for use with TAPIRLink. John correctly points out that the TDWG list should have been copied from the start, and I am remedying that now. I have condensed the thread to only the main points to make it easy to digest, and suggest we continue the discussion here. The current point in the discussion relates to the SimpleDarwinCore being flat in nature, and therefore why it holds a subset of all the DwC terms documented in the standard. Thanks, Tim On Aug 7, 2010, at 7:59 AM, John Wieczorek wrote: > Hi folks, > > I wish that this conversation had taken place on the tdwg-content > list so that others might take advantage of the discussion, but I > don't feel comfortable moving someone else's conversations there.

Fwd: Taxon Concept dilemma

I think that a "someone" is always asserting such an opinion - Smith and Jones included. There is no Platonic ideal of a particular species. Every single classification is a matter of educated opinion. Smith has one opinion and Jones has another opinion. Brown may step in and decide that Smith's opinion is the correct one - but that's just another opinion. Consumers of the classification choose whose opinions are the most useful. A taxon is always related to a taxon-assigner. In this sense, "circumscription" is perhaps not the best way to think about it, because very few assigners actually determine taxa by enumerating organisms. The idea of researchers creating taxa, and third parties adjudicating them to arrive at the "true" classification, is too limited. It's third parties all the way down. ///ark

Hi, On short notice I have been invited to give a presentation on TDWG and the Sept. meeting to the monthly meeting of the Woods Hole Oceanographic Institution biology department on Monday morning. I have looked at the presentations on the TDWG outreach site but they seem a bit too technical for biologists. MIght anyone have any TDWG materials geared toward non-technical biologists?
