Monitoring SPARQL Endpoint Status

چکیده
We demo an online system that tracks the availability of over four-hundred public SPARQL endpoints and makes up-to-date results available to the public. Our demo currently focuses on how often an endpoint is online/offline, but we plan to extend the system to collect metrics about available meta-data descriptions, SPARQL features supported, and performance for generic queries.

Monitoring the Status of SPARQL Endpoints

متن کاملHow Good Is Your SPARQL Endpoint? - A QoS-Aware SPARQL Endpoint Monitoring and Data Source Selection Mechanism for Federated SPARQL Queries
Due to the decentralised and autonomous architecture of the Web of Data, data replication and local deployment of SPARQL endpoints is inevitable. Nowadays, it is common to have multiple copies of the same dataset accessible by various SPARQL endpoints, thus leading to the problem of selecting optimal data source for a user query based on data properties and requirements of the user or the appli...
متن کاملSpEnD: Linked Data SPARQL Endpoints Discovery Using Search Engines
Linked data endpoints are online query gateways to semantically annotated linked data sources. In order to query these data sources, SPARQL query language is used as a standard. Although a linked data endpoint (i.e. SPARQL endpoint) is a basic Web service, it provides a platform for federated online querying and data linking methods. For linked data consumers, SPARQL endpoint availability and d...
متن کاملSPARQL Query Construction with Monitoring Service for Endpoints
Many databases in life sciences have been provided in Resource Description Framework (RDF) with their SPARQL endpoints. To support a user in constructing SPARQL queries, we developed a service called SPARQL Builder. Although SPARQL Builder makes a user write a query for obtaining data from LOD, empty results or incorrect data might be retrieved by the query if the SPARQL endpoint for the query ...
متن کاملSPARQLES: Monitoring public SPARQL endpoints
We describe SPARQLES: an online system that monitors the health of public SPARQL endpoints on the Web by probing them with custom-designed queries at regular intervals. We present the architecture of SPARQLES and the variety of analytics that it runs over public SPARQL endpoints, categorised by availability, discoverability, performance and interoperability. To motivate the system, we gives exa...
