Introduction The problem The gap between XML and RDF technologies Document generation XSLT Template XPath SPARQL 3 Faisal Alkhateeb and S´ ebastien Laborie Towards Extending and using SPARQL for Modular Document Generation

Our contribution Our contribution Bridge the gap between XML and RDF technologies Document generation SPARQL Template 4 Faisal Alkhateeb and S´ ebastien Laborie Towards Extending and using SPARQL for Modular Document Generation

Our contribution Our contribution Contribution: A SPARQL extension which supports the generation of XML documents based on templates Definition of a template language based on our SPARQL extension Advantages: Templates modularity Templates reusability Templates readability 4 Faisal Alkhateeb and S´ ebastien Laborie Towards Extending and using SPARQL for Modular Document Generation
