Bug Fixes

BioPortal 5.0.0 (2017-Feb-06)

This release represents an overhaul of our user interface, using bootstrap as the front-end framework to enable immediate and longer-term improvements. (Since the October 2016 release, we have also made a number of minor changes, mostly under the hood, and recently added a few significant features to the Recommender; Release Notes will be added shortly for those changes.)

Please Note: Although we are aware of some bugs that have surfaced since the transition, so far they have been relatively minor and most can be worked around by re-sizing the page or changing tabs. We will be working to squash those bugs in the next few days, so please bear with us for this brief period.


  • Released new BioPortal user interface, including the features described below.
  • Implemented new UI framework based on boostrap, enabling cleaner management of all UI elements.
  • Redesigned the front page to provide cleaner and more informative look and feel, and put key features front and center.
  • Added graph to show top ontology access counts, replacing table with similar information.
  • Redesigned header to move most links to the menu bar, simplifying header and unifying it across all pages.
  • Redesigned footer to include appropriate and cleanly presented content, including social links, unified across all pages.

Bug Fixes

  • Fixed an issue with the prompt for the ontology search on the front page, which would not produce desired results.
  • Fixed layout issues in front page header.
