Rob Vesse, a software engineer, discusses tools for semantic web development, highlighting his work with the DotNetRDF project and personal frustrations with existing tools. He provides recommendations for data conversion, editing, query prototyping, and management tools, including examples like Rapper, RDFEditor, and Fuseki. The document emphasizes the importance of open-source solutions and shares links for further exploration of the mentioned tools.
Everyday Tools for the Semantic Web Developer
- 1. Everyday Tools for the Semantic Web Developer Rob Vesse rvesse@dotnetrdf.org Cray Inc
- 2. About Me • Software Engineer at Cray • Writing up my PhD Thesis in spare time – “Link Integrity for the Semantic Web” • Run the dotNetRDF Project – Started January 2009 – Latest Releases • 0.5.1 Beta (APIs) • 0.4.0 Beta (Toolkit) 12/6/2011 http://www.dotnetrdf.org 2
- 3. My Life as a Semantic Web Developer • Constantly working with different data sources, formats, vocabularies etc. • Was frustrated by limited tooling around conversion, query prototyping and editing – Especially the *nix/Java bias of available tooling • Seemed pointless to keep writing tiny Java/.Net programs to do everyday tasks 12/6/2011 http://www.dotnetrdf.org 3
- 4. Tools • All free to use/open source – All of which I’ve used at one stage or another – Some of which I use on a daily basis • Demos – Going to demo my favourite tool in each category – Slides have links to other useful tools and will be available on SlideShare 12/6/2011 http://www.dotnetrdf.org 4
- 5. Data Conversion - rapper • Part of the Redland family of tooling by Dave Beckett – http://librdf.org/raptor/rapper.html • *nix based – needs cygwin on Windows • Example Usage: – rapper –g –o turtle input.rdf > output.ttl 12/6/2011 http://www.dotnetrdf.org 5
- 6. Editing - rdfEditor • Part of the dotNetRDF Toolkit – http://www.dotnetrdf.org/content.asp?pageID=rd fEditor • Windows only – Mono does not support the required APIs unfortunately • Notepad replacement for RDF editing with syntax highlighting, auto-complete and validation capabilities 12/6/2011 http://www.dotnetrdf.org 6
- 7. Query Prototyping - Fuseki • Part of the family of Jena Tooling – http://openjena.org/wiki/Fuseki • Provides a HTTP server for SPARQL Query and Update runnable from the command line • Can use persistent TDB storage (Jena’s native triple store) • Example Usage: – java –jar fuseki-sys.jar --update --loc=DB 12/6/2011 http://www.dotnetrdf.org 7
- 8. Management - Store Manager • Part of the dotNetRDF Toolkit – http://www.dotnetrdf.org/content.asp?pageID=St ore%20Manager • .Net Based – needs Mono on *nix • GUI for working with a variety of Triple Stores through a standard interface 12/6/2011 http://www.dotnetrdf.org 8
- 10. Other Recommended Tools • Conversion – riot (Jena ARQ) • Query Prototyping – SparqlGUI (dotNetRDF Toolkit) – Twinkle (by Leigh Dodds) • Management – Sesame Windows Client 12/6/2011 http://www.dotnetrdf.org 10
