The logic of RDF and SPARQL
The logic of RDF and SPARQL is a scholarly work, published in 2006. The main subjects of the publication include Simple Knowledge Organization System, linked data, information retrieval, Resource Description Framework, RDF Schema, computer science, XML, Semantic Web, SPARQL, cwm, RDF query language, and stream processing. The problem of the canonical representation of the answer set will be introduced, since bnodes introduce a behaviour similar to the null values in SQL.
