National Center for Biomedical Ontology
• Mission – To create software for the application of
ontologies in biomedical science and clinical care
• NCBO Partners– Stanford University - Dr. Mark A. Musen– Mayo Clinic - Dr. Christopher G. Chute– University of Buffalo - Dr. Barry Smith– University of Victoria - Dr. Margaret-Anne

REST Web Services
• Accessed via HTTP– http://rest.bioontology.org/{parameter}
• Each unique URL is a representation of some object
• Operations include GET, POST, PUT, DELETE • Lightweight, easy to build

Ontology View
• A View is a subset of one or more ontologies– also referred to as a value set or slim
• Anyone can create a View – does not need to be the ontology “owner”

View Extraction Web service
• Given a term identifier, extracts all children • Parameters
– Ontology version identifier– Term identifier– Output ontology name

Using Views in Your Application
• List all views– Get list of all views in BioPortal – Get all versions of a given View
• Views are accessible via all BioPortal web services– Get term – get all details about a term – Search – find terms in a View – Widgets – form field auto-complete widget

Ontology Web Services
• Access Ontologies and Views (Value sets or Slims) – Search – search by term or term identifier across all
ontologies in BioPortal – Term – get details about a term including it’s URI,
super- and sub-classes, properties– Hierarchy – get parent or children terms – Mapping – get mappings between terms – Notes – get comments/new term proposals added to
the ontology– RDF – get RDF snippet for term or entire ontology

Ontology Web Services
• Widgets– Jump To – auto-complete function to select term
and Jump To BioPortal to view term details– Term-selection widget – auto-complete function
and can return term URI, term ID or term name– Visualize widget – view the ontology structure and
relations– Tree widget – view the ontology tree
Code for widgets is available on BioPortal
