- Installing ClioPatria triplestore on mac os
ClioPatria is a “SWI-Prolog application that integrates SWI-Prolog’s the SWI-Prolog libraries for RDF and HTTP services into a ready to use (semantic) web server”. It is actively developed by the folks at the VU University of Amsterdam and is freely available online. While at a conference last week I saw a pretty cool demo (DIVE) […]
- Installing GraphDB (aka OWLIM) triplestore on mac os
GraphDB (formerly called OWLIM) is an RDF triplestore which is used – among others – by large organisations like the BBC or the British Museum. I’ve recently installed the LITE release of this graph database on my mac, so what follows is a simple write up of the steps that worked for me. Haven’t played […]
- An interactive Turtle shell
Wouldn’t it be nice to have an interactive environment where you quickly hack together an RDF model and then show it to your clients or colleagues in a more accessible format – i.e. a diagram? Don’t know if there’s anything like that already, but the other day while polishing up the OntosPy library I’ve taken […]
- Nature.com subject pages available online!
Subject pages are pages that aggregate content from across nature.com based on the tagging of that content by NPG subject ontology terms. After six months of work on this project we’ve finally launched the first release of the site, which is reachable online at http://www.nature.com/subjects. Hooray! This has been a particularly challenging experience cause I’ve […]
- Textmate bundle for Turtle and Sparql
I recently ran into the Textmate bundle for Turtle, an extension for the Textmate osx editor aimed at facilitating working with RDF and SPARQL. If you happen to be using these technologies, well I’d suggest you take a look at the following post. The Resource Description Framework is a general-purpose language for representing information which […]
- ESWC 2013 – report from the conference
Last week I attended the European Semantic Web Conference (ESWC’13) in Montpellier and had a really good time meeting old friends and catching up with the latest research in this area. In this post I’ll collect a few pointers to papers and ideas that caught my attention. For a high level summary of the talks, […]
- Semantic Web Cheat Sheets
Here’re a couple of reference sheets that can become handy if you’re doing any semantic web related work. I’ve found both of them online, and will add more to this list as they come along. N3 Language Cheatsheet I found this table on this blog post: http://aabs.wordpress.com/semantic-web/the-n3-cheat-sheet/. Some of the formatting was messed up on […]
- Inspecting an ontology with RDFLib
RDFLib (homepage) is a pretty solid and comprehensive rdf-programming kit for Python. In a previous post I already discussed what pythonic options are currently available out there for doing semantic web programming; after some more in depth testing I realized that Rdflib is the most accessible and complete of them all (in fact many of […]
- Hack4Europe! – Europeana hackathon roadshow, June 2011
Europeana is a multilingual digital collection containing more than 15 millions resources that lets you explore Europe’s history from ancient times to the modern day. Europeana API services are web services allowing search and display of Europeana collections in your website and applications. The folks at Europeana have been actively promoting the experimentation with their […]
- RDF programming with AllegroCL and AllegroGraph
Allegro Common Lisp (wikipedia) is a commercial implementation of the Common Lisp programming language developed by Franz Inc. Allegro CL provides the full ANSI Common Lisp standard – but more interestingly for me, it also provides a very comprehensive suite of tools for semantic web programming. So I decided to give it a go, in […]
