- RDF programming with AllegroCL and AllegroGraph
Allegro Common Lisp (wikipedia) is a commercial implementation of the Common Lisp programming language developed by Franz Inc.

- Survey of Pythonic tools for RDF and Linked Data programming

One of the cool things you get to do with a Kindle is being able to access your pdf library on the go; however soon enough I ran into the problem of getting all the pdf files to show up with the right metadata, e.g. name, author, creator etc.. I thought that was a simple […]
