- http://biohackathon.org/d3sparql/ - JavaScript natually fits for querying a SPARQL endpoint which provides a REST service returning the result in the JSON format. The d3sparql.js library provides functions executing a SPARQL query by Ajax call (XMLHttpRequest) and visulaizing results by the D3 library. Basically, this library transforms the SPARQL Query Results JSON Format (aka. application/sparql-results+json) into several JSON formats which major D3 layouts can accept. Many of the examples are borrowed from bl.ocks.org and bost.ocks.org. The d3sparql.js library is distributed under the same license as D3.js's (BSD license).

- https://jena.apache.org/documentation/query/manipulating_sparql_using_arq.html - Tutorial - Manipulating SPARQL using ARQ - When you’ve been working with SPARQL you quickly find that static queries are restrictive. Maybe you want to vary a value, perhaps add a filter, alter the limit, etc etc. Being an impatient sort you dive in to the query string, and it works. But what about little Bobby Tables? And, even if you sanitise your inputs, string manipulation is a fraught process and syntax errors await you. Although it might seem harder than string munging, the ARQ API is your friend in the long run.

- Simple Knowledge Organization System - Simple Knowledge Organization System (SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary. SKOS is part of the Semantic Web family of standards built upon RDF and RDFS, and its main objective is to enable easy publication and use of such vocabularies as linked data.
