23rd BioModels Database Release

Hinxton, Saturday 11th August 2012

We are pleased to announce the twenty-third release of BioModels Database!

BioModels Database now publicly provides 142916 models. This corresponds to 867 models published in the literature and 142050 models coming from the Path2Models project.

With this release, several new models have been published and numerous have been updated. Moreover new services are now available (for example related to the access to models from the Path2Models project) while others have been improved (such as the model browsing feature based on a tree of Gene Ontology terms or the BioPAX export). Please read below for more information.


A search engine is now provided for retrieving models coming from the Path2Models project. More information about how to use it is available from the Path2Models page.

For those wishing to obtain the complete set of those models, three archives are now available from our FTP server.

Finally performance improvements were made related to the speed of browsing those models.

Gene Ontology tree

The way to browse the curated models via Gene Ontology terms has been updated. The tree now fully works on all main web browsers. Moreover, when clicking on one GO term, the list of relevant models is displayed in the right panel.

BioPAX export

The BioPAX L3 converter used to generate our exports has been updated. As well as fixing several issues, this introduces the usage of URLs. This should enable users to build on this RDF-based representation of the models for preforming cross repository queries.

Web services

The Java library provided to access the web services is now available via the EBI Maven repository (in addition to the download from SourceForge). For more information about this library and how to configure your Maven configuration file, please refer to the web services documentation page.

SBML files with URLs

Since the 21st release, in addition to the SBML versions of the models with annotations encoded with MIRIAM URNs, BioModels Database provides SBML files with annotations encoded using URLs.

From this release, the provided archives containing only SBML models make use of URLs instead of the URNs. For the models published in the literature, archives with all the exports are available which still contain a copy of the models with URNs.

Content summary

Here is a classification of the curated models based on their Gene Ontology annotation:
