Firefox Extension for NCBO API Key: To make it easier to test Web service calls from your browser, we have released the NCBO API Key Firefox Extension. This extension will automatically add your API Key to NCBO REST URLs any time you visit them in Firefox. The extension is available at Mozilla's Add-On site. To use the extension, follow the installation directions, restart Firefox, and add your API Key into the “Options” dialog menu on the Add-Ons management screen. After that, the extension will automatically append your stored API Key any time you visit

Upcoming software license change: The next release of NCBO software will be under the two-clause BSD license rather than under the currently used three-clause BSD license. This change should not affect anyone’s use of NCBO software and this change is to a less restrictive license. More information about these licenses is available at the site: Please contact with any questions concerning this change.

(Release date February 2011)

BioPortal Release 2.5

New features in this release include the following:

  • Support for structured notes and term requests: Users can now use BioPortal to request that content developers add new terms or update other ontology content. BioPortal provides a structured template for making such requests, allowing users to suggest preferred names, synonyms, and definitions for the requested terms. BioPortal stores the requests as structured notes that are attached to the ontology and that other ontology tools, such as Protégé, will be able to use.
  • Support for email notifications to interested parties whenever a BioPortal user creates new notes for an ontology of interest. (If you would like to subscribe to notifications about a particular ontology, please send email to support at We will have an interactive form to sign-up for notifications shortly.)
  • Prototype Web services to generate RDF representation for terms in ontologies in BioPortal (see documentation [1] for details).
  • Web services for retrieving instance information for OWL ontologies [1]. We are planning to release a user interface for viewing instances shortly.
  • New ontology widgets that developers can embed on their Web sites, including an ontology tree widget that allows Web-site authors to present a display of an ontology or an ontology subtree for any BioPortal ontology in any Web page.
  • Preview release of Bio-Mixer, a mashup tool that provides extremely flexible browsing and exploration of ontologies and their mappings
