@herb52 Sorry for the delay. I would like to help you resolve this issue, but I do not understand it very well and this might benefit from a call. You can contact me by email to set that up.
Hello Tucotuco,
thanks for your reply. Yes you are right, my question is in some points too in general and in others to detailed so that it is confusing for you. Sorry. So please allow me to start from scratch again.
My question is about: How to store DarwinCore information/data inside still-images in XMP-format (using ExifTool to write it).
(1) My knowledge about DarwinCore is based on your internet page https://exiftool.org/TagNames/DarwinCore.html
(2) ExifTool is a Perl application to read and write metadata from/into images (or videos). ExifTool is created and maintained by Phil Harvey; it is able to manage Exif, Iptc-IIM and also XMP metadata. As part of XMP it can read/write DarwinCore metadata (with namespace xmp-dwc). These xmp-dwc metadata have been defined many years ago based on an example-image-file sent by an user to Phil Harvey (as far I know). Current supported tags is decribed on https://exiftool.org/TagNames/DarwinCore.html
(3) Let me explain my problem with the following example. On page "Darwin Core XML guide" https://dwc.tdwg.org/xml/ chapter 2.7.1 we find an example of a DarwinCore file (+) in XML
For DarwinCore class Event I created an XMP-file with ExifTool: <?xpacket begin='' id='W5M0MpCehiHzreSzNTczkc9d'?>
Currently it's mostly used as answer c) "PreservedSpecimen" is a vocabulary term for the property "dwc:basisOfRecord" i.e. used in the "dwc:Event" Class See https://rs.gbif.org/vocabulary/dwc/basis_of_record_2022-02-02.xml
Hello bart-v
Thanks for your reply. The dictionary you mentioned contains strings/names of "classes" listed on "Darwin Core quick reference guide" -- all "classes" without properties -- but also 2 classes that have properties: MaterialSample and Occurence
So I think it is not the class, but only names with identical strings.
As you said: Currently it's mostly used as answer c) I agree, because I did not find any example XML-file that has "PreservedSpecimen" used as "class".
So what is "PreservedSpecimen" (and others) designed for". To be used in future?
Best regards herb
Good question, I have no idea :)
Hello,
I am new to DarwinCore (DwC). I want to store DwC-specific data inside photos using the structures and tags (elements of the structure) of xmp-dwc supported by Exiftool. For xmp-dwc please see https://exiftool.org/TagNames/DarwinCore.html
I started with "Darwin Core quick reference guide" on https://dwc.tdwg.org/terms/ Here I see
Now my question for the "logical structure" is: Is (A) or (B) to be used in order to store DwC-data properly?
Maybe an example that shows one of the "classes without properties" would be helpful.
Remark: I asked this question also on tdwg-dwc https://github.com/tdwg/dwc/issues/414 , but without success. So I hope to get an answer/comment here.
Thanks for your comments/answers in advance Best regards herb
