use of the terms dcterms:rightsHolder and dcterms:accessRights in existing databases
by Steve Baskauf 03 Jul '12

03 Jul '12

The terms dcterms:rightsHolder and dcterms:accessRights are "imported" from Dublin Core into the Darwin Core record-level vocabulary. I am interested in them for two reasons: there are several issues with the use of those terms as RDF predicates, and they differ from the terms suggested for use in rights management in the draft Audubon Core vocabulary. What I am wondering is how widely are they actually used in databases by our community? If you maintain a database, do you use them? Steve -- Steven J.

Re: [tdwg-content] minimum/maximum elevation and depth - usage and priority?
by Aaike De Wever 03 Jul '12

03 Jul '12

Dear John, Dear all, Thanks a lot for the answers so far. I am still curious about a good example of the min/max use, at first I thought the trawl sampling was a good example as well, but I guess it rather applies if you sampled an area with a certain radius around the provided coordinates. As most data we will encounter will come from a single point/elevation/depth, I am just a little worried that it may puzzle data providers that they have to provide both min and max. With best regards, Aaike Hi Aaike, These values are indeed meant to capture the range of possible elevation/depth or the extent of them. If there upper and lower bounds are the same, then the values in the minimum and maximum should be the same.

minimum/maximum elevation and depth - usage and priority?
by Aaike De Wever 02 Jul '12

02 Jul '12

Dear all, While composing a template and recommendations for the Darwin Core fields to supply for the BioFresh project <http://www.freshwaterbiodiversity.eu/>, similar to what Peter Desmet did for herbaria in Apple Core <http://code.google.com/p/applecore/>, I came across a number of terms which I haven't yet completely understood and hope to get some feedback on from this community. The terms I am referring to are: * minimumElevationInMeters - maximumElevationInMeters http://rs.tdwg.org/dwc/terms/minimumElevationInMeters - http://rs.tdwg.org/dwc/terms/maximumElevationInMeters The lower limit of the range of elevation (altitude, usually above sea level), in meters. * minimumDepthInMeters - maximumDepthInMeters http://rs.tdwg.org/dwc/terms/minimumDepthInMeters - http://rs.tdwg.org/dwc/terms/maximumDepthInMeters The lesser/greater depth of a range of depth below the local surface, in meters.

Beginner's Guide to RDF now available
by Steve Baskauf 01 Jul '12

01 Jul '12

The Beginner's Guide to RDF is now available at the TDWG-RDF Task Group's website via the RRL http://code.google.com/p/tdwg-rdf/wiki/Beginners The guide is intended to serve as an introduction for persons who are not already familiar with RDF and OWL, and as a reference for those who would like organized access to reference material on those topics. The information is presented with minimal formal language and includes functional examples from the biodiversity informatics community. Thanks to the members of the Task Group who provided clarification and examples during discussion prior to writing the guide and especially to Paul Murray and Bob Morris who provided helpful feedback on drafts of the guide.

LSID Resolution Service using DDDS/DNS
by Julien Cigar 19 Jun '12

19 Jun '12

Hello, I'm reading the LSID spec and there are some things that are some things that are a little cloudy to me. The spec says that the client should query the DNS for NAPTR records for the domain name "lsid.urn.arpa", but it seems that the URN NID part "lsid" has not been established at IANA (lsid.urn.arpa is unresolvable) ? Why ? I wondered if it's enough to query the DNS of the "authority identification" part of the LSID (domain name) for a _lsid._tcp SRV record and assume that this entry is a valid resolution service for the given LSID ? If not, what's the proper way to find a resolution service for, let's say, "urn:lsid:blah.my.domain:foo:12345" ? Thank you Best regards, Julien -- No trees were killed in the creation of this message. However, many electrons were terribly inconvenienced.

Citizen Science Interest Group home
by andrea thomer 31 May '12

31 May '12

Hello all, Over the last few months Arthur Chapman and I have been (unfortunately rather slowly) pulling together a charter for a Citizen Science Interest Group (CSIG); this charter (available at http://bit.ly/JPQpal) was ratified on March 9. We've had a bit of trouble pulling a wiki together, so until we get that figured out, we're using a Google Group for messages and other information. If you'd like to join, please request an invitation through the Google Group: https://groups.google.com/group/tdwg-CSIG If you have any questions, comments, or concerns, please don't hesitiate to post to the group's forums, or email me or Arthur directly. Thanks, Andrea Thomer RA, Center for Informatics Research in Science and Scholarship Graduate School of Library and Information Science University of Illinois at Urbana-Champaign
