The deadline for the Call for Abstracts<https://biodiversitynext.org/call-for-abstracts/> for the joint Biodiversity_Next<https://biodiversitynext.org/> conference in Leiden, The Netherlands, 19-25 October 2019 has just been extended to 5 April 2019. This conference also serves as the annual meeting for Biodiversity Information Standards (TDWG<https://www.tdwg.org/>). With over sixty programmed symposia, workshops, and other events<https://biodiversitynext.org/list-of-symposia-and-workshops/> the conference will bring together major international organisations, research scientists, and policy makers to look at the horizon of data-driven biodiversity and geodiversity research and uses.
Make sure to submit your abstract by this new 5 April deadline. Conference registration is scheduled to open 26 March with a limited number of super early bird registrations available.

Hi all,
This is a follow up to an earlier email I sent to the list, and I'm hoping someone new might read this and have ideas.
The official Darwin Core XML Schema Definition for Darwin Core Terms (https://dwc.tdwg.org/xml/tdwg_dwcterms.xsd) makes reference at line 63 in a comment to a dublin_core.xsd file, which in my estimation is a modified dcterms.xsd from Qualified Dublin Core. Unfortunately I can't find any dublin_core.xsd files through the dwc.tdwg.org site or Github to confirm this.
I'm currently working on implementing Darwin Core into a GeoNetwork plugin using these XML Schema Definitions and I believe this dublin_core.xsd file explains an issue we had. Specifically, using the files specified in https://dwc.tdwg.org/xml/tdwg_dwcterms.xsd in our plugin results in dcterms namespace elements (e.g., dcterms:type) not being recognized as record level terms.
Based on line 63 of https://dwc.tdwg.org/xml/tdwg_dwcterms.xsd, my guess is that dublin_core.xsd is (was?) a modified Qualified Dublin Core dcterms.xsd where the element declarations are changed to, for example, <xs:element name="modified" substitutionGroup="dwc:anyRecordLevelTerm"/> INSTEAD OF <xs:element name="modified" substitutionGroup="dcterms:date"/>
I'm hoping someone on this mailing list might know whether this is true, or know of whether dublin_core.xsd exists in the format I predict.
Thanks very much for your time,
Kim
