이러한 GO 데이터는 GOC를 통해 다운 받을 수 있으며 여러가지 포멧으로 제공이 되고 있다.
go-basic.obo
This is the basic version of the GO filtered such that the graph is guaranteed to be acyclic, and annotations can be propagated up the graph. The relations included are is_a, part_of, regulates, negatively_regulates and positively_regulates. This version excludes relationships that cross the 3 main GO hierarchies. This is the version that should be used with most GO-based annotation tools.
go.obo and go.owl
These files contain the core GO ontology in two formats, OBO and OWL-RDF/XML. This view includes relationships not in the filtered version of GO including has_part and occurs_in. The set of relationships used is likely to extend over time. Many of these relationships may not be safe for propagating annotations across, so this version should not be used with legacy GO tools. This version currently excludes relationships to external ontologies.
go-plus.owl
This version of GO includes cross ontology relationships (axioms) and imports additional required ontologies. This version is only available in OWL. Currently the only external ontology dependency is to CHEBI, but this will change in the future.
이외에도 SQL 및 XML 포멧도 지원하고 있으며 이를 통해 원하는 데이터를 쉽게 얻을 수 있다.
이러한 GO 데이터의 손쉬운 활용을 위해 여러가지 방법을 통해 데이터를 이용할 수 있으며 AmiGO browser를 통해 웹 기반의 정보 획득이 가능하다.
또한 GO database mirrors server를 통해 터미널 환경에서 직접 자료를 얻을 수 있으며 ebi에서 서버를 제공한다.
