Discoverability of SPARQL endpoints in linked open data
Heiko Paulheim, Sven Hertling · 2013
Abstract. Accessing Linked Open Data sources with query languages such as SPARQL provides more flexible possibilities than access based on derefencerable URIs only. However, discovering a SPARQL endpoint on the fly, given a URI, is not trivial. This paper provides a quantitative analysis on the automatic discoverability of SPARQL endpoints using different mechanisms. 1
