Knows methods such as Direct Mapping of Relational Data to RDF (2012) for transforming data from the relational model (keys, values, rows, columns, tables) into RDF graphs.
Integrating Open Sources and Relational Data with SPARQL
The authors of this paper believe that the possibility to use SPARQL as a front end to heterogeneous data without significant cost in performance or [...]
RDF, SPARQL and Semantic Repositories
This massive slide presentation covers a LOT of ground, including. It begins with the benefits of using RDF, RDFS/OWL entailment rules and how they can [...]
Mapping Relational Database into OWL Structure with Data Semantic Preservation
This paper proposes a solution for migrating an RDBMS into an appropriate structure for the Semantic Web (i.e., RDF). The solution takes an existing RDBMS [...]
Capturing Relational Schemas and Functional Dependencies in RDFS
Mapping relational data to RDF is an important task for the development of the Semantic Web. To this end, the W3C has recently released a [...]
Relational Database to RDF Translation in the Cultural Heritage Domain
The author argues that simple algorithms for automatically mapping relational data to RDF are wasteful and inefficient. Instead, mapping can be significantly improved by using [...]
Accessing Relational Data with RDF Queries and Assertions
This paper presents a hybrid RDF storage model that combines relational data with arbitrary RDF metadata, as implemented in the RDF storage layer of the [...]
Suggesting Mappings from Relational Databases to Ontologies
This video discusses the CONTOMAP project, which seeks to solve the problem of mapping from relational databases to ontologies. Several possible approaches are outlined: naive, [...]
Providing Linked Data
This video presentation covers the whole spectrum of Linked Data production and exposure. It begins with a grounding in Linked Data principles and best practices, [...]
Answering SPARQL Queries over Databases under OWL 2 QL Entailment Regime
This paper presents an extension of the ontology-based data access platform Ontop that supports answering SPARQL queries under the OWL 2 QL direct semantics entailment [...]
