How to explore SPARQL endpoint?


In this article you will learn:
- how to explore SPARQL endpoint with Ontorion™ SPARQL Tools for Excel
- about SPARQL autocomplete tool from Cognitum
Ontorion™ SPARQL Tools for Excel latest release offers two new features enriching the SPARQL experience. First one is Explore SPARQL endpoint tool, which enables to get a quick overview of the data content of the endpoint. Second is SPARQL autocomplete tool, which guides user throughout writing the query with intelligent autocomplete hints.

Motivation

A growing amount of data is made public via SPARQL endpoints. You can explore the data by asking SPARQL queries. One of the most famous SPARQL endpoints is DBpedia - a semantic version of Wikipedia. Many public institutions expose some of their data in such an open way as well. A good example is The Environment Agency of England and Wales, which publishes data about bathing water quality .
The basic building block of SPARQL data set is a triple. It is a statement of the form subject-predicate-object. Apart from that, the structure of the data can be quite loosely defined. Thus it may sometimes be difficult to explore a new SPARQL endpoint for the first time.
