2019 Communications in Computer and Information Science  
An R2RML processor is a tool that, given a set of R2RML rules and a relational database, generates an RDF dataset.  ...  Knowledge graphs are often generated based on rules that apply semantic annotations to raw or semi-structured data.  ...  R2RML and RML differences RML is an extension of R2RML and, thus, follows the core concepts of R2RML's specification, such as Triples Maps, Term Maps, Subject Maps, and so on.  ...

Declarative Data Transformations for Linked Data Generation: The Case of DBpedia [chapter]

Ben De Meester, Wouter Maroy, Anastasia Dimou, Ruben Verborgh, Erik Mannens
2017 Lecture Notes in Computer Science  
We validate that our approach can map and transform dbpedia in a declaratively defined and aligned way.  ...  Since complex data transformations remain out of scope for mapping languages, these steps are often implemented as custom solutions, or with systems separate from the mapping process.  ...  More customization is enabled by solutions that allow embedded scripts inside mapping documents such as R2RML-F [11] .  ...
