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. It is in beta, with a demonstrations site available at http://amigo2.berkeleybop.org. Please be aware that this site changes frequently and may still have downtimes (see the AmiGO_Labs page for the usual caveats).
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 backend GOlr loading code is available on Google Code, please see the GOlr page for more details.
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.
The current version is 2.0 (in trunk). It is in active development.
The AmiGO 2 presentation given at the BOSC 2012 is available at the Berkeley BOP site.
