<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We have some data that covers Taxa, Names and Concept relationships.<o:p></o:p></span></p>

</span></span><![endif]><span lang="EN-US">Concept + relationship tables that contain details about the name + references where the name has been used in a taxonomic sense (ie not nomenclatural information) – this is specifically a link between the Name and
a Reference</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have fairly permanent Ids for the Taxon Name (nomenclatural) and the Concepts, but I now what to consider the ID to cover the whole Taxon (ie the Nomenclatural data + taxon rank + parent name + accepted name, etc, as “we” understand
them). (Probably equivalent to the taxonID in Dwc)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem is this tends to be much more dynamic data – ie, in this particular case we have aggregated data from a variety of providers and are in continual revision of this data - as we revise the data the details such as the accepted
name may change – this troubles me a bit, because this could be seen as fundamentally changing the definition of the object behind the taxonID. However, I suspect this is a common case that people find themselves in – ie revision/tidying of aggregated datasets
must be quite common.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would prefer to NOT change the taxonID every time we revise that data (taking the angle that these changes are corrections, so are not changing the object itself).<o:p></o:p></p>
<p class="MsoNormal">Should it be OK to have an object type like this, that is likely to change, but keep the ID permanent for it – ie accept that some object types are quite dynamic?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The only other option is to maintain a hideous version audit trail, that probably hinders the use of the data more than it benefits the end user by providing “stability”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any thoughts?<o:p></o:p></p>
