Re: [tdwg-tag] RDF N3

I like the sound of the 'compactness' of the format, but I worry that there is a lack of tools that support the format (ie browsers, mainly). It is quite nice to naturally navigate the rdf world with a standard browser. But for transfer standards, I suppose this wouldn't matter.

string literals vs. uris for dwc:recordedBy, dwc:identifiedBy, and dwc:georeferencedBy in RDF
by Steve Baskauf 01 Jun '10

01 Jun '10

The definition for the Darwin Core term recordedBy http://rs.tdwg.org/dwc/terms/index.htm#recordedBy says "A list (concatenated and separated) of names ...". The examples given are string literals. However, when using this term as a predicate in RDF, it would seem preferable to use a URI to an RDF representation of the entity (if one exists) rather than a string literal. For example, can I use: <dwc:recordedBy rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"/> rather than <dwc:recordedBy>Steven J. Baskauf</dwc:recordedBy> ?

Call for Software Bazaar entries open for Conference on Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio)
by Hilmar Lapp 26 May '10

26 May '10

The Call for Software Bazaar entries is now open for the inaugural conference on Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio), at http://ievobio.org/ocs/index.php/ievobio/ 2010. See below for instructions. The Software Bazaar features presenters demonstrating their software live on a laptop. At iEvoBio, this session takes the place of a poster session, and will be between 1.5-2 hours in duration. Conference attendees will be able to walk from one demonstration to the next and open a conversation with the presenters. Please also see our FAQ for this information (http://ievobio.org/faq.html#software). The Software Bazaar is part of the interactive afternoon program on the first conference day. Entries should be software aimed at advancing research in phylogenetics, evolution, and biodiversity, and can include interactive visualizations that have been pre-computed (such as SVGs, or Google Earth-compatible KML files). Submissions consist of a title, which will typically be the name of the software (or visualization method) being presented, the URL of a website where more information about the software can be obtained, and the license under which the source code is available. The provided website must contain a link to where the source code (and possibly binaries) can be downloaded. If it is not obvious from the provided website, the submission must describe what the software does. Reviewers will judge whether a submission is within scope of the conference (see above), and need to be able to verify whether the open- source requirement(*) is met. Presenters are expected to bring their own laptops for presentation, and any auxiliary devices necessary (such as a mouse). Power will be available at the presentation tables (110V/60Hz, US-style plugs; international presenters need to bring a suitable adaptor). Please let the organizing committee know as much in advance as possible if you expect to have unusually high demands for wireless network bandwidth. Note that commercial marketing activities are not permitted - presenters wishing to promote commercial or proprietary services or products should contact the Evolution conference about exhibitor space. Review and acceptance of Software Bazaar submissions will be on a rolling basis. The deadline for submission is the morning of the first day of the conference (June 29). As the number of Software Bazaar presentation slots is finite, we cannot guarantee the availability of slots up until the day of the conference. We cannot accept submissions until the open-source requirements are met. We ask all submitters of Software Bazaar presentations to be willing to also serve as reviewers of such, as described above. Softwar Bazaar demonstrations are only 1 of 5 kinds of contributed content that iEvoBio will feature. The other 4 are: 1) Full talks (closed), 2) Lightning talks, 3) Challenge entries, and 4) Birds-of-a- Feather gatherings. The Calls for Challenge entries (http://ievobio.org/challenge.html ) and Lightning Talks (same submission URL as above) remain open, and information on the Birds-of-a-Feather session is forthcoming. More details about the program and guidelines for contributing content are available at http://ievobio.org. You can also find continuous updates on the conference's Twitter feed at http://twitter.com/iEvoBio. iEvoBio is sponsored by the US National Evolutionary Synthesis Center (NESCent) in partnership with the Society of Systematic Biologists (SSB). Additional support has been provided by the Encyclopedia of Life (EOL). The iEvoBio 2010 Organizing Committee: Rod Page (University of Glasgow) Cecile Ane (University of Wisconsin at Madison) Rob Guralnick (University of Colorado at Boulder) Hilmar Lapp (NESCent) Cynthia Parr (Encyclopedia of Life) Michael Sanderson (University of Arizona) (*) iEvoBio and its sponsors are dedicated to promoting the practice and philosophy of Open Source software development (see http://www.opensource.org/docs/definition.php) and reuse within the research community. For this reason, software to be demonstrated to conference attendees must be licensed with a recognized Open Source License (see http://www.opensource.org/ licenses/), and be available for download, including source code, by a tar/zip file accessed through ftp/http or through a widely used version control system like cvs, Subversion, git, Bazaar, or Mercurial. Authors are advised that non-compliant submissions must be revised to meet the requirement by June 27 at the latest, and in the event that presentation slots run out, precedence is established by the date they are first found in compliance, not the date of submission.

Darwin Core generic XML with attributes
by Steve Baskauf 21 May '10

21 May '10

This recent discussion reminds me of a question that I have been wondering about for several months and hadn't gotten around to bringing up: can you have a Darwin Core XML representation where an element has a literal value and an attribute? If the XML is RDF, then I think the answer is pretty much "no" as I just found out with the W3C Validator. However, in generic XML I don't think there is any rule that says that one can't have any attribute that one wants. The only guidance I know of on the subject is: http://rs.tdwg.org/dwc/terms/guides/xml/index.htm#implement It states that the value of a Darwin Core property should be the content of the element rather than stating the value as an attribute. However, I have the situation where I want to store or transfer two somewhat equivalent representations of the value of a property: a string literal form and a URI form. In the example we've been talking about, I would like my generic (non-RDF) XML to do something like this: <?xml version="1.0" encoding="UTF-8"?> <dwr:SimpleDarwinRecordSet xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dwc="http://rs.tdwg.org/dwc/terms/" xmlns:dwr="http://rs.tdwg.org/dwc/xsd/simpledarwincore/" > <dwr:SimpleDarwinRecord> <dwc:occurrenceID rdf:resource="http://herbarium.org/hb123456">http://herbarium.org/hb123456</dwc:occurrenceID> <dwc:recordedBy rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me">Steve Baskauf</dwc:recordedBy> <dwc:basisOfRecord rdf:resource="http://rs.tdwg.org/dwc/dwctype/PreservedSpecimen">PreservedSpecimen</dwc:basisOfRecord> ... more elements, mostly with string literal values... </dwr:SimpleDarwinRecord> </dwr:SimpleDarwinRecordSet> This would meet the basic guidelines of the Darwin Core XML Guide in that the literal values would be the contents of the elements. What I don't know is if the inclusion of the rdf:resource attributes would invalidate the XML if it were validated against someone's schema that was silent about attributes or if the schema would have to explicitly say that having an rdf:resource attribute was a valid option. I think I don't know enough about XML schemas ... The reason why I would like to maintain/transfer both types of values (literal and URI) is so that I could use the XML data to generate both HTML and RDF if I wanted. The HTML would tell humans that the occurrence was a PreservedSpecimen, but the RDF would tell a linked data client that the occurrence was a http://rs.tdwg.org/dwc/dwctype/PreservedSpecimen . I realize that for my own internal use, the XML can have any format I want, but if I were exporting XML for general public use, would it be bad to use the approach above? Steve As an aside, I wanted to see exactly what the definition was for rdf:resource However, the usual namespace for rdf: (http://www.w3.org/1999/02/22-rdf-syntax-ns#) doesn't seem to include "resource" in the defined properties. Very odd! Maybe I'm just missing something... -- Steven J.

Referring to GBIF distribution map in RDF
by Roderic Page 11 May '10

11 May '10

Dear All, I'm interested in referring to a GBIF distribution map in RDF, and am having fun figuring out how to do it. One way is to use a c-squares- based URI, see http://iphylo.blogspot.com/2010/05/referring-to-one-degree-s quare-in-rdf.html (http://tinyurl.com/33ba4kt). The idea is that each 1° × 1° square in a GBIF map has it's own c- squares-based URI, e.g. http://bioguid.info/csquare:3317:364 , and hence a distribution would be a list of these URIs (perhaps with the number of records from each square). Any thoughts on this approach, and whether we have an existing vocabulary to describe these relationships?
