Understands the difference between SQL query language (which operates on database tables) and SPARQL (which operates on RDF graphs). – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 Synaptica Tech Talks: Data Modeling with Graphs https://ld4pe.dublincore.org/learning_resource/synaptica-tech-talks-data-modeling-with-graphs/ Wed, 08 Mar 2017 06:53:18 +0000 https://ld4pe.dublincore.org/learning_resource/synaptica-tech-talks-data-modeling-with-graphs/ This tutorial explores data modelling by comparing and contrasting traditional relational databases with property graph databases and RDF Linked Data graph databases. Also discusses the benefits of reusing ontologies and vocabularies from well-known and authoritative sources.

]]> How Is SPARQL Different From SQL? https://ld4pe.dublincore.org/learning_resource/how-is-sparql-different-from-sql/ Mon, 09 Jan 2017 06:45:30 +0000 https://ld4pe.dublincore.org/learning_resource/how-is-sparql-different-from-sql/ This video explains how the SPARQL query language differs from SQL. Highlighted is the ability of SPARQL to handle complex joins that would be too time-consuming using SQL. Also, SPARQL joins do not require a high degree of a priori knowledge of the data scheme.

]]> RDFProv: A Relational RDF Store for Querying and Managing Scientific Workflow Provenance https://ld4pe.dublincore.org/learning_resource/rdfprov-a-relational-rdf-store-for-querying-and-managing-scientific-workflow-provenance/ Wed, 23 Nov 2016 05:50:23 +0000 https://ld4pe.dublincore.org/learning_resource/rdfprov-a-relational-rdf-store-for-querying-and-managing-scientific-workflow-provenance/ Provenance metadata has become increasingly important to support scientific discovery, reproducibility, result interpretation, and problem diagnosis in scientific workflow environments. The provenance management problem concerns the efficiency and effectiveness of the modeling, recording, representation, integration, storage, and querying of provenance metadata. The authors present an approach to provenance management which they claim "seamlessly integrates the interoperability, extensibility, and inference advantages of Semantic Web technologies with the storage and querying power of an RDBMS to meet the emerging requirements of scientific workflow provenance management". In this paper, they elaborate on the design of a relational RDF store, called RDFProv, which is optimized for scientific workflow provenance querying and management.

]]> Querying Linked Data https://ld4pe.dublincore.org/learning_resource/querying-linked-data-3/ Fri, 21 Oct 2016 05:39:20 +0000 https://ld4pe.dublincore.org/learning_resource/module-2-querying-linked-data-2/ This module looks in great detail at SPARQL and introduces approaches for querying and updating semantic data. It covers the SPARQL algebra, the SPARQL 1.1 protocol, and provides examples for reasoning over Linked Data. The module uses examples from the music domain, which can be directly tried out and ran over the MusicBrainz dataset. This includes gaining familiarity with the RDFS and OWL languages, which allow developers to formulate generic and conceptual knowledge that can be exploited by automatic reasoning services in order to enhance the power of querying.
