What is discovery

discovery is a software library which aims to ease the development of decision support tools exploiting omics RDF databases. The library offers a dedicated query language that can be used in several runtime environments (Browser/JS, Node/JS, JVM/Scala).

discovery is developed as part of the work package "Creating FAIR e-resources for knowledge mining" for the national infrastructure for metabolomics and fluxomics - MetaboHUB

features

  • Programming/building request with immutables objects
  • Querying several RDF content (SPARQL Endpoint, RDF File, RDF content)
  • Federated Query
  • Handling lazy page results
  • Subscribe to SPARQL query status events
  • Stringify request and configuration to ease transport
  • Decorating the building nodes with additional information

Dependencies - RDF Software libraries

this software development is based on RDFJS (RDF JavaScript Libraries) and RDF4J
