MGD data access is available through MouseMine (http://www.mousemine.org), an instance of InterMine that offers flexible querying, templates, iterative querying of results and linking to other model organism InterMine instances. MouseMine access is also available via a RESTful API, with client libraries in Perl, Python, Ruby, Java and JavaScript. MouseMine contains many data sets from MGD, including genes and genome features, alleles, strains and annotations to GO, MP and DO.
