For nested discussion you can use the : as first character for indenting texts and mark your comments by your signature ~~~~ (becomes replaced by the Wiki). Recommendation: add new topics on the top, not on the bottom.


A few remarks on the CSPP

Reading through the profile, I have a few remarks (Mathias Dillen 13:32, 4 June 2020‎ (CET)):

  • kindOfMaterial / type: Shouldn't we use Dublin Core's controlled vocabulary for type (e.g. PhysicalObject)? And use dwc:basisOfRecord for PreservedSpecimen. There is less consensus for how to define what kind of specimen it is (e.g. herbarium sheet), but in MIDS the recommendation is to use dwc:preparations.
    Short question of understanding, what is MIDS ? (I have trouble understanding some less common abbreviations ;-) --Andreas Plank (talk) 12:08, 11 June 2020 (CEST)
    Apologies. Minimum Information for Digital Specimens. More info. --Mathias Dillen (talk) 13:02, 15 June 2020 (CEST)
  • Why do we recommend dwc:fieldNumber and not dwc:recordNumber?
  • Why do we recommend dc:created and not dwc:eventDate? The latter is much more strongly connected to the gathering event, rather than the digital object.
     I don’t know for sure, but reading the definition of dwc:eventDate and reading the meaning of event (in etymonline.com: “that which happens”) one has to determine the event type, I guess; so dwc:eventDate can be any event. And dc:created is per definition «Date of creation of the resource» which I would interpret more as to belong to the herbarium sheet of paper that has been created. --Andreas Plank (talk) 13:49, 7 January 2021 (CET)

Relations of CETAF Specimen Preview Profile (CSPP) and expressed RDF somewhat baffling

From analysing returned RDF (e.g. http://id.snsb.info/snsb/collection/97112/153455/93009 accessed on 26th November 2019) we get the RDF, e.g. on Linux by 

wget  --quiet --header='Accept: application/rdf+xml'  --header='Content-Type: application/rdf+xml'  --output-document="id.snsb.info⁄snsb⁄collection⁄97112⁄153455⁄93009.rdf" "http://id.snsb.info/snsb/collection/97112/153455/93009"

… and find in the RDF file: 

<!-- … -->
    <rdf:Description rdf:about="http://id.snsb.info/snsb/collection/97112/153455/93009"><!-- OK -->
        <dc:title>Erysiphe cruciferarum Opiz ex L. Junell</dc:title><!-- OK -->
        <dwc:collectionCode>BSMeryscoll</dwc:collectionCode><!-- OK -->
        <dwc:collectionID>3</dwc:collectionID><!-- OK -->
        <dwc:datasetName>The Erysiphales Collection at the Botanische Staatssammlung München</dwc:datasetName><!-- OK -->
        <dc:relation>http://www.botanischestaatssammlung.de/DatabaseClients/BSMeryscoll/About.cfm</dc:relation><!-- OK -->
        <dwc:kindOfMaterial>PreservedSpecimen</dwc:kindOfMaterial><!-- baffling: who defines dwc:kindOfMaterial ?-->
        <dc:type>PreservedSpecimen</dc:type><!-- ?OK -->
    </rdf:Description>    
<!-- … -->

… which contains baffling RDF, because there is no definition of <dwc:kindOfMaterial>PreservedSpecimen</dwc:kindOfMaterial>, I can find—is there or is it yet to be defined somewhere the dwc:kindOfMaterial?

I myself have difficulties to understand the CSPP proposal on one side and the mapping to the equivalent (classical) RDF on the other side, given no further documentation (yet). We should more clarify by example the relation of CSPP and classical RDF; or I have not understood it yet. --Andreas Plank (talk) 13:09, 26 November 2019 (CET)

Example with commented CSPP elements

Perhaps provide a plain RDF example and a XML example. Plain RDF example (note that & is not escaped):
