In that view, an organism might be at a location because it was a representative of a native species, or because it was managed at that location by humans. In that perspective, it would not make sense to use the value "invasive" with dwc:establishmentMeans because that is more of a property of a species at a location rather than an individual organism at that location and time. <br><br>Steve<br><br>Quentin Groom wrote: <o:p></o:p></p><div><div><p class=MsoNormal>I've been working on a proposal to improve Darwin Core for use with invasive species data.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The proposal is detailed on GitHub at <a href="https://github.com/qgroom/ias-dwc-proposal/blob/master/proposal.md" target="_blank">https://github.com/qgroom/ias-dwc-proposal/blob/master/proposal.md</a>.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The proposal is for a new term "origin" and suggested vocabularies for establishmentMeans and occurrenceStatus.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I'd welcome your feedback on the proposal.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>From my perspective it provides some needed clarity on the establishmentMeans and occurrenceStatus fields, but also adds the origin that is needed for invasive species research and for conservation assessments.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I'm not sure of the best way to discuss this, but if you have concrete proposals for changes you might raise them as issues on GitHub, as well as mentioning them here.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Regards<o:p></o:p></p></div><div><p class=MsoNormal>Quentin<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal><br clear=all><o:p></o:p></p><div><div><div><div><div><div><div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Dr. Quentin Groom<o:p></o:p></p></div><div><p class=MsoNormal>(Botany and Information Technology)<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Botanic Garden Meise<o:p></o:p></p></div><div><p class=MsoNormal>Domein van Bouchout<o:p></o:p></p></div><div><p class=MsoNormal>B-1860 Meise<o:p></o:p></p></div><div><p class=MsoNormal>Belgium<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><a href="http://orcid.org/0000-0002-0596-5376" target="_blank">ORCID: 0000-0002-0596-5376</a><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Landline; +32 (0) 226 009 20 ext. 364<o:p></o:p></p></div><div><p class=MsoNormal>FAX: +32 (0) 226 009 45<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>E-mail: <a href="mailto:quentin.groom@plantentuinmeise.be" target="_blank">quentin.groom@plantentuinmeise.be</a><o:p></o:p></p></div><div><p class=MsoNormal>Skype name: qgroom<o:p></o:p></p></div><div><p class=MsoNormal>Website: <a href="http://www.botanicgarden.be" target="_blank">www.botanicgarden.be</a><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div></div></div></div></div></div></div></div></div><p class=MsoNormal><br><br><o:p></o:p></p><pre>-- <o:p></o:p></pre><pre>Steven J.
