]]> Simple SPARQL Tutorial: Understanding Named Graphs https://ld4pe.dublincore.org/learning_resource/simple-sparql-tutorial-understanding-named-graphs/ https://ld4pe.dublincore.org/learning_resource/simple-sparql-tutorial-understanding-named-graphs/#respond Thu, 13 Aug 2015 03:26:19 +0000 https://ld4pe.dublincore.org/learning_resource/simple-sparql-tutorial-2729-understanding-named-graphs/ This tutorial explains how when uploading many RDF datasets using a tool such as Fuseki, they can be merged into one Default Graph. This also occurs when the FROM keyword is used to query multiple datasets, and determining provenance is difficult. Using Named Graphs can help to remedy this situation. This topic is discussed further in the next video in the series.
