MarkLogic: SPARQL and XQuery together

Tue, 19 Jan 2016 14:59:48 +0000

This exercise covers the use of SPARQL and XQuery together in a few different ways. This involves running a series of queries on the BBC news documents and related triples loaded into the database in a previous exercise. This is just one of several tutorials in a sequence, and they should be done in order to gain the most benefit.

Querying the Linked Archives Hub data using SPARQL

Sat, 16 Jan 2016 13:43:28 +0000

This blog post provides a few sample SPARQL queries that can be used as a starting point for exploring an unfamiliar dataset. The queries are intended to give users an idea of what is possible and a platform to build on. The dataset used in these examples is LOCAH archival data which, like most archives, is hierarchically organized into collection level and sub-levels.
