Mapping between RDF and XML with XSPARQL
TLDR
We present the XSPARQL language that, by combining XQuery and SPARQL, allows to query XML and RDF data using the same framework and transform data from one format into the other. Expand

On the Semantics of Heterogeneous Querying of Relational, XML and RDF Data with XSPARQL
XSPARQL is a transformation and query language that caters for heterogenous sources: in its present status it is possible to transform data between XML and RDF formats due to the integration of theExpand

Schema-Agnostic Query Rewriting in SPARQL 1.1
TLDR
We introduce a new method of schema-agnostic query rewriting, where arbitrary conjunctive queries over OWLaQL are rewritten into equivalent SPARQLa1.1 queries in a way that is fully independent of the actual schema. Expand

Semantic Modelling of Smart City Data
TLDR
We present examples of data that can be collected from cities, discuss issues around this data and put forward some preliminary thoughts for creating a semantic description model to describe and help discover, index and query smart city data. Expand
