Currently in production.


AmiGO 2 is a project to create the next generation of AmiGO--the current official web-based set of tools for searching and browsing the Gene Ontology database.

For an overview of features, please see the overview documentation.

For installation information, please see the installation documentation.

AmiGO 2

While we sometimes talk about AmiGO 2 as a unified project, its component parts are currently broken into three groups in two different repositories: GOlr (backend and loading) and the perl and JavaScript portions of the frontend.

GOlr: The Backend

The most fundamental change from the old AmiGO is the backend containing the Gene Ontology data--the MySQL relational database, has been replaced and is now loaded directly into a Solr document store, dubbed GOlr.

This new backend not only provides the engine for running AmiGO, but can be used by anybody as a web service by itself. More information is available on the GOlr page.

The Perl and JavaScript Frontend

The AmiGO 2 frontend is the user layer over the GOlr backend. Some components of AmiGO 2 use perl libraries to communicate with the GOlr backend (and other remote sources), process the results, and display them to the user. Other components (JavaScript APIs) communicate directly with the GOlr backend.

JavaScript API

The beta public JavaScript APIs will eventually be available at While a permanent home for the JSAPI is being considered as we move into beta, preview documentation is available at .


The current version is 'trunk'. It is in active development.

The backend GOlr loading code is available on Google Code, please see the GOlr page for more details.

The frontend code is broken between AmiGO 2-specific code repo and a more generic JavaScript/JavaScript API code repo, both are hosted on GitHub. The former can be found here and the latter here.

More detailed instructions on installation are pending, but the front page both both repositories are a great place to start.


There is mailing list for AmiGO 2 development here.



The backend is developed in Ubuntu 12.04 and 12.10. It has also been run successfully on Mac OSX 10.7. Given these two, it is expected to run on any fairly well-behaved modern *nix platform.


AmiGO 2 should be compatible with most modern operating system/browser combinations with good JavaScript and CSS support. However, at this time, extensive testing has not been done. AmiGO 2 is mostly developed with Firefox, Chrome, and Opera on several versions of GNU/Linux.

Repositories and Trackers

The repositories and trackers for the elements that compose AmiGO 2 are:

  • Backend
    • GOlr - Solr schema and definitions for GO (in the AmiGO 2 repository)
    • OWLTools - preferred loader
  • Frontend
    • BBOP JS - general JS code
    • AmiGO 2 - JavaScript/Perl code and web server deployment; GO specific BBOP JS code
