Bill de hÓra: Snowflake APIs


RDF is worth learning for a different reason — the profound enlightenment experience you will have when you finally get it. That experience will make you a better format and data API designer for the rest of your days, even if you never actually use RDF itself a lot. (You can get some beginning experience with RDF fairly easily by writing and modifying simple files like FOAF and DOAP for social networks and software projects, or RDFa extensions for XHTML.)

ARQ - Property Paths

A property path expression (or just 'path') is similar to a string regular expression but over properties, not characters. ARQ determines all matches of a path expression and binds subject or object as appropriate. Only one match is recorded - no duplicates for any given path expression, although is the path is used in a situation where it's initial points is already repeated in a pattern, then this duplication is preserved.

RDF Store Benchmarks with DBpedia

In the course of my diploma thesis, I evaluated the performance of several RDF stores when small pieces of information are requested from a large dataset (DBpedia infoboxes plus two very small sets). The benchmark queries employ varying levels of joins and constraints.
