- Ontospy 1.9.8 released
Ontospy version 1.9.8 has been just released and it contains tons of improvements and new features. Ontospy is a lightweight open-source Python library and command line tool for working with vocabularies encoded in the RDF family of languages. Over the past month I’ve been working on a new version of Ontospy, which is now available for download […]
- Installing Stardog triplestore on mac os
Stardog is an enterprise-level triplestore developed by clarkparsia.com. It combines tools to store and query RDF data with more advanced features for inference and data analytics – in particular via the built-in Pellet Java reasoner. All of this, combineded with a user experience which is arguably the best you can currently find in the market. […]
- 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 […]
- 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 […]
- A few useful Linked Data resources
Done a bit of semantic web work in the last couple of weeks, which gave me a chance to explore better the current web-scenario around this topic. I’m working on some example applications myself, but in the meanwhile I thought I’d share here a couple of quite useful links I ran into. Development Tools: Quick […]
- Survey of Pythonic tools for RDF and Linked Data programming
In this post I’m reporting on a recent survey I made in the context of a Linked Data project I’m working on, SAILS. The Resource Description Framework (RDF) is a data model and language which is quickly gaining momentum in the open-data and data-integration worlds. In SAILS we’re developing a prototype for rdf-data manipulation and […]
- Installing RDFlib on osX
RDFlib is a Python library for working with RDF, a simple yet powerful language for representing information. Installing it is easier than what you might think. I googled it and it seems that several people had problems (missing components mainly) with this.. but in my case it was easy-beasy (well you need to have easy-install): […]
- Modeling Representations (take 2)
I wrote something in the last weeks about the difficulties related to the modeling of representations and their contents. So today I just read this article by Stefano Mazzocchi, which basically hints at the same issue, but from an ‘RDF perspective’. It’s a very interesting article, so I just wanted to quote and comment a […]
