The OntoBrowser tool was developed to manage ontologies (and controlled terminologies e.g. CDISC SEND). The primary goal of the tool is to provide an online collaborative solution for expert curators to map code list terms (sourced from multiple systems/databases) to preferred ontology terms. Other key features include visualisation of ontologies in hierarchical/graph format, advanced search capabilities, peer review/approval workflow and web service access to data.

Key Features

  • Web based collaborative ontology curation
  • Interactive hierarchical/graph visualisation
  • Cross ontology searching
  • Synonym mapping
  • Automated mapping of similar matching synonyms
  • Central database for all ontologies
  • Version tracking
  • Review/Approve workflow
  • Email notification
  • Full curator audit trail/history



OntoBrowser: a collaborative tool for curation of ontologies by subject matter experts
Bioinformatics, Volume 33, Issue 1, 1 January 2017, Pages 148–149


The OntoBrowser was initially developed in frame of the eTOX consortium. It has received support from the Innovative Medicines Initiative Joint Undertaking under grant agreement n°115002, resources of which are composed of financial contribution from the European Union's Seventh Framework Programme (FP7/2007-2013) and EFPIA companies' in kind contribution. We would like to formally acknowledge the contribution to the eTOX project of all scientists and other staff involved.
