PRSC: From PG to RDF and back, using schemas

open access: hybridSemantic Web
Property graphs (PG) and RDF graphs are two popular database graph models, but they are not interoperable: data modeled in PG cannot be directly integrated with other data modeled in RDF. This lack of interoperability also impedes the use of the tools of one model when data are modeled in the other.

Inference of Shape Expression Schemas Typed RDF Graphs

open access: green, 2021
We consider the problem of constructing a Shape Expression Schema (ShEx) that describes the structure of a given input RDF graph. We employ the framework of grammatical inference, where the objective is to find an inference algorithm that is both sound i.e., always producing a schema that validates the input RDF graph, and complete i.e., able to ...

Answering SPARQL queries modulo RDF Schema with paths

open access: green, 2013
SPARQL est le langage de requête standard pour interroger des graphes RDF. Dans son instanciation stricte, il ne propose que des requêtes en fonction de la sémantique de RDF et n'interprète donc pas les vocabulaires exprimés en RDFS ou OWL. Plusieurs extensions de SPARQL ont été proposées pour interroger les données RDF en fonction de vocabulaires RDFS

Capturing Relational Schemas and Functional Dependencies in RDFS

open access: bronzeProceedings of the AAAI Conference on Artificial Intelligence, 2014
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 Recommendation for the so-called direct mapping of relational data to RDF. In this work, we propose an enrichment of the direct mapping to make it more faithful by transferring also semantic ...

Building RDF-Schema Based Knowledge Map for Knowledge Management Systems [PDF]

open access: closedJournal of Systemics, Cybernetics and Informatics, 2003
This paper attempts to implement the semantic web paradigm, which enables the semantic search of knowledge and information on the web environment, by adopting RDF, RDF-schema and Dublin core data element structure in the process of building knowledge map.

Direct Mapping and Turtle Ontology for Management of Indonesian Movies Knowledge [PDF]

open access: yesMATEC Web of Conferences, 2022
Web 2.0 or conventional web has developed into Web 3.0, known as semantic web. Semantic web technology requires ontology as the backbone in understanding a concept of knowledge.

Mapping RDF Databases to Property Graph Databases

open access: yesIEEE Access, 2020
RDF triplestores and property graph databases are two approaches for data management which are based on modeling, storing and querying graph-like data. In spite of such common principle, they present special features that complicate the task of database ...

Database Security in RDF Terms

open access: yesScientific Bulletin, 2023
Databases are perhaps the most attacked and vulnerable elements in the online environment as far as organizations are concerned. The databases contain the most important information of an organization and its confidential data, along with those of its ...
