With an ever-growing dependence on the Web and the continuously increasing importance of large-scale data sharing, integration, and reuse, natural science researchers, geoscience, biology, library science, health care, the humanities, just to name a few, have also taken an increasing interest in the Semantic Web. The U.S. Semantic Technologies Symposium (US2TS) series provide a forum to ease the division between computer science, natural science, and academia/government/industry. The list of program sessions is now available at http://us2ts.org/2019/posts/program.html<https://urldefense.proofpoint.com/v2/url?u=http-3A__us2ts.org_2019_posts_pr…> Contact -------------------------------------- All questions about submissions should be emailed to contact-us2ts2019(a)googlegroups.com<mailto:contact-us2ts2019@googlegroups.com> Sponsors -------------------------------------- The following sponsors<http://us2ts.org/2019/posts/sponsor.html> have expressed their financial support for US2TS 2019: National Science Foundation<https://urldefense.proofpoint.com/v2/url?u=https-3A__nsf.gov_&d=DwMFaQ&c=im…>, Alfred P.

Re: [tdwg-content] Darwin Core and dcterms:location
by Tim Robertson 12 Dec '18

Hi Kim, (moving our private discussion onto this list) Thanks for the links. As far as I can see the “custom” dublin_core.xsd existed in all DwC releases from 2009 up until 2013-10-23 where it was removed. In that removal, the references to the location were also commented out (I presume meaning the modified XSD was no longer needed) though. For you to still find references to it suggests you might be using an older version of the Darwin Core XSD – is that possible? John / Peter: Do you recall why it was removed? To save searching, the modification to the DC xsd appeared to contain only the following:  <xs:element name="Location" substitutionGroup="dwc:anyClass"> <xs:complexType> <xs:choice maxOccurs="unbounded"> <xs:element ref="dwc:anyIdentifier"/> <xs:element ref="dwc:anyLocationTerm"/> <xs:element ref="dwc:anyRecordLevelTerm"/> </xs:choice> </xs:complexType> </xs:element> The commented out reference in the DwC xsd:  (see https://dwc.tdwg.org/xml/tdwg_dwc_class_terms.xsd) From: tdwg-content <tdwg-content-bounces(a)lists.tdwg.org> on behalf of Kim Mortimer <K.Mortimer(a)dal.ca> Date: Wednesday, 12 December 2018 at 20.34 To: "tdwg-content(a)lists.tdwg.org" <tdwg-content(a)lists.tdwg.org> Subject: Re: [tdwg-content] Darwin Core and dcterms:location To the TDWG mailing list and whomever it may concern, Darwin Core uses a Dublin Core element, dcterms:location, in its definition of classes and elements. However, no current XSD files for Dublin Core (that I can find) define location as an element. For reference, the current Dublin Core XSD files that I am familiar with are available at http://dublincore.org/schemas/xmls/qdc/ Given that dcterms:location is therefore an undefined element, the Darwin Core XML is invalid. This is important to me, and my employer MERIDIAN, because we are implementing Darwin Core in a GeoNetwork metadata schema plugin for our repository. To allow other documents to be validated against our schema within GeoNetwork, the entire plugin XML (which for us includes the Darwin Core XML) must be valid. I previously sent an email about this in September but did not receive any useful advice at the time. Development on our metadata repository has progressed without this element since then, as we have been tracking down other errors in GeoNetwork, but this is the current 'blocking' problem for us. The Darwin Core XSD files reference a dublin_core.xsd in their comments, which is said to contain dcterms:location. My best guess at what this refers to is https://github.com/tdwg/dwc/blob/2011-10-26/xsd/dublin_core.xsd - which is from a previous version of Darwin Core, and appears to be a custom version of http://dublincore.org/schemas/xmls/qdc/2008/02/11/dcterms.xsd - so it unclear whether this is correct or not. Given that TDWG is responsible for Darwin Core, I am hopeful that someone will have a tip or solution. My alternative is to define dcterms:location myself as a custom insertion into Dublin Core, but based on the comments in Darwin Core files I believe some suitable XSD must exist.

To the TDWG mailing list and whomever it may concern, Darwin Core uses a Dublin Core element, dcterms:location, in its definition of classes and elements.

I am seeking speakers for a proposed Biodiversity Next symposium
by Simpson, Annie 06 Dec '18

06 Dec '18

Hello, TDWG list members, I've submitted the following abstract to Biodiversity Next and would like to know if any of you would like to give a talk? I've requested a 90-minute slot. If you are interested, please email me with your name, affiliation, title, and 300 word (or less) abstract, and we will see where this goes. How can specialized databases integrate information and work better together? Is following Darwin Core enough? Invasive species databases and other specialized biodiversity information systems are being called more and more to share their information with one another (Zeller et al. 2005; Holdren 2013). Because of differences in data content and database purpose, much information from smaller datasets can be lost during the integration process into larger databases such as BISON, iDigBio, GBIF, and others (Costello et al. 2013). The effort required for cross-walking data fields and for modifying database structure to accommodate new information is significant (Diepenbroek et al. 2014). Darwin Core extensions have been, and continue to be, created to facilitate the sharing of specialized datasets (Byrd 2018). However, following the guidelines set out in these extensions can be insufficient when their structure leans toward the flexible vs. requiring the use of controlled terms. Participants in this symposium will be encouraged to share examples -- both challenges and successes -- they have encountered during their efforts to combine specialized datasets. - Byrd C (2018) Adaptation of Darwin Core Standards and Development of New Standards for Geologic Specimens.
