Any RDF example?

Dear list,

As far as I've been working with DWC I've been just using Simple Darwin Core in XML files but now I'd like to add semantic information and therefore I've planned to use RDF.

I've been looking around but couldn't find any good example of a DWC RDF, could you please provide me with one? Even better if it contains the FOAF info of the author... :)

Thanks in advance, Jaime

Hi Jamie,

I have mocked up this example, but I am not sure it is what the standard authors were intending. See my post on December 23rd.

Here is my example http://rdf.geospecies.org/datasets/Bcb50c3c-13f5-4c0c-A6de-5f422e2b88c7.rdf

http://rdf.geospecies.org/datasets/Bcb50c3c-13f5-4c0c-A6de-5f422e2b88c7.rdfYou can click through the various parts via uriburner

http://linkeddata.uriburner.com/about/html/http://rdf.geospecies.org/dataset...

I also have a lot of species information in RDF, (about 2 million triples) but it is not in DarwinCore at:

http://lod.geospecies.org/

The about page is here: http://about.geospecies.org/

This data set is part of the Linked Open Web or LOD, which is explained here: http://linkeddata.org/

Here is the diagram of the Linked Open Data Cloud: http://www4.wiwiss.fu-berlin.de/bizer/pub/lod-datasets_2009-03-05.html

I have some examples of SPARQL queries here: http://about.geospecies.org/sparql.xhtml

Here the page for one of my species http://lod.geospecies.org/ses/iuCXz.html

Here is the RDF for that species http://lod.geospecies.org/ses/iuCXz.rdf

I have tried to follow the DarwinCore as close as I can without breaking what I have working.

In the future, I plan to rework my occurrence RDF into something like my example above, but with some additional fields.

I think I can come up with a version of RDF for occurrences in DarwinCore that also follows Linked Data best practices.

Hope this helps. :-)

Hi Peter,

Just a couple of comments about the content of http://rdf.geospecies.org/datasets/Bcb50c3c-13f5-4c0c-A6de-5f422e2b88c7.rdf...

The entity dwc:Dataset no longer exists, though the identifier dwc:datasetID does.

The value "http://maps.google.com" is an appropriate value for dwc:georeferenceSources, but not for dwc:georeferenceProtocol.

The repeated use of basisOfRecord for topics within the primary topic is interesting. I wonder if the occurrence topic should actually have a more refined basisOfRecord, such as "http://rs.tdwg.org/dwc/dwctype/PreservedSpecimen".

Thanks for the examples,

John
