C-SPARQL: a Continuous Query Language for RDF Data Streams
This article defines C-SPARQL, an extension of SPARQL whose distinguishing feature is the support of continuous queries, i.e. queries registered over RDF data streams and then continuously executed. Queries consider windows, i.e. the most recent triples of such streams, observed while data is continuously flowing. Supporting streams in RDF format guarantees interoperability and opens up importa...
متن کاملRDF-GL: A SPARQL-Based Graphical Query Language for RDF
In an era of ever-increasing information needs, the ability to query large databases quickly and efficiently has come to play a major part. For a large share, this growing need is addressed by tools and languages aimed at performing complex queries on distributed data. However, the intuitiveness of designing such complex queries has only been addressed to a limited extent, making such tools ava...
متن کاملSPARQL Protocol And RDF Query Language
Beyond doubt, the world wide web has become central to the business reality of companies and to the personal reality of the majority of people in their everyday lives. Large web communities like Facebook or YouTube make people stay on the internet for a very long time. Companies use at the very least e-mail for communication, while most of them also use other services on the web, e.g. for order...
متن کاملT-SPARQL: A TSQL2-like Temporal Query Language for RDF
In this paper, we present a temporal extension of the SPARQL query language for RDF graphs. The new language is based on a temporal RDF database model employing triple timestamping with temporal elements, which best preserves the scalability property enjoyed by triple storage technologies, especially in a multi-temporal setting. The proposed SPARQL extensions are aimed at embedding several feat...
متن کاملQueryMed: An Intuitive SPARQL Query Builder for Biomedical RDF Data
We have developed an open-source SPARQL query builder and result set visualizer for biomedical data, QueryMed, that allows end users to easily construct and run translational medicine queries across multiple data sources. QueryMed is flexible enough to allow queries relevant to a wide range of biomedical topics, and can run queries across multiple SPARQL endpoints. It is designed to be accessib...
