separated. Whereas nomenclators such as IPNI and Zoobank use the LSID taxon name vocabulary, other databases use vocabularies such as Darwin Core, which rather conflate names and concepts. It's not clear to me how this situation arose, but it somewhat defeats
the point of having standards.</span><o:p></o:p></p>

our profile of ISO 19115 for the latter, and the question will come up as to whether to use elements from TCS, DwC, EML, NCBII extension to ISO 19115, or other. By default I would expect the front runner to be TCS but it appears few if any major systems have
ever gone that route – I have looked at ITIS, COL, TROPICOS, WoRMS, IPNI, GBIF, AFD/APNI, more… the nearest would perhaps be AFD/APNI (hence copying Paul on this email) however their “ibis” schema, though apparently based originally on TCS,
<a href="http://biodiversity.org.au/xml/ibis-20120909.xsd">http://biodiversity.org.au/xml/ibis-20120909.xsd</a> , does not make any explicit reference to the TCS schema so far as I can see. (Note also the cited schema definition

<br>
In the context of the discussion which has been going on in the TDWG RDF mailing list, I have been thinking more about the issue of how to deal with DwC terms which state "Recommended best practice is to use a controlled vocabulary...". That would be dcterms:type,
dwc:language, dwc:basisOfRecord, dwc:sex, dwc:lifeStage, dwc:reproductiveCondition, dwc:behavior, dwc:establishmentMeans, dwc:occurrenceStatus, dwc:disposition, dwc:continent, dwc:waterBody, dwc:islandGroup, dwc:island, dwc:country, dwc:verbatimCoordinateSystem,
dwc:georeferenceVerificationStatus, dwc:identificationVerificationStatus, dwc:taxonRank; dwc:nomenclaturalCode, dwc:taxonomicStatus, dwc:relationshipOfResource, and dwc:measurementType .<o:p></o:p></p>

<p class="MsoNormal">We here have had all sorts of problems using other people's vocabularies - they never quite match the data we have. Our solution has been to use the standard terms where possible, but to mint our own where needed. We create RDF objects
and to declare them as being the correct type.<o:p></o:p></p>

this does mean that the world becomes fragmented into a number of site-specific vocabularies that cannot be machine-reasoned over. The underlying reason for this is that that is in fact the way the world actually is at the moment, and there's not a lot of
help for it.</span><o:p></o:p></p>

the vocabulary that you are creating. It's a never-ending job. It might be an idea to have the design guideline that no enumeration class defined by the vocabulary shall have more than 10 values. It's arbitrary, but it will keep people from being carried away
subdividing types into a hierarchy that they think is a good idea, but which doesn't match the data people already have.</span><o:p></o:p></p>
