Vanderbilt's Semantic Web Working Group has a new SPARQL endpoint. You can read about it here: http://baskauf.blogspot.com/2017/07/how-and-why-we-set-up-sparql-endpoint.html

I have blogged about using BaseX to build a web service that supports content negotiation and serves RDF metadata as XML, Turtle, and JSON-LD https://baskauf.blogspot.com/2017/03/a-web-service-with-content-negotiation.html

I have written a new blog post at http://baskauf.blogspot.com/2017/03/controlled-values-again.html explaining how the draft TDWG Standards Documentation Specification (https://github.com/tdwg/vocab) would apply to controlled vocabularies. If you've been following the Darwin Core Hour webinars, both the most recent one and the upcoming one are on the topic of controlled vocabularies, so you might want to check out this post. We are also in the midst of the 30 day public comment period for the Standards Documentation Specification, so if there is anything you don't like about what I've written in the post, you need to comment in the next couple of weeks or you will miss your chance to have an impact on the specification.

I have blogged about my experiments with using named and unnamed RDF graphs with three SPARQL endpoints: Callimachus, Stardog, and Blazegraph. The results were kinda weird and in some ways disturbing. http://baskauf.blogspot.com/2017/02/sparql-weirdness-of-unnamed-graphs.html

I have written a new blog post about building a multilingual SPARQL-based web app that searches for information about Chinese temple buildings. It's got a Digital Humanities spin, but a similar thing could be done with biodiversity informatics data. http://baskauf.blogspot.com/2016/11/sparql-based-web-app-to-find-chinese.html

I've written a followup to my earlier post about turning GBIF Darwin Core Archives into RDF: Fixing the Octopus. http://baskauf.blogspot.com/2016/11/fixing-octopus.html

I've completed a new blog post about my experiment of turning four diverse Darwin Core Archives from GBIF and elsewhere into RDF, then merging them with the Bioimages graph to create a combined graph of 8 million triples describing 13 thousand organisms. The resulting triples are downloadable and also queryable at a public SPARQL endpoint. http://baskauf.blogspot.com/2016/11/guid-o-matic-meets-dwc-rdf-octopus.html
