24th BioModels Database Release

Hinxton, Wednesday 12th December 2012

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

BioModels Database now publicly provides 142973 models. This corresponds to 923 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 versions of the metabolic and non-metabolic models were generated by the Path2Models project, as well as graphical representations in SBGN for the metabolic ones. Finally we are introducing, for testing and feedback purposes, a RDF/XML version of the models published in the literature. Please read below for more information about this release.


BioModels Database now provides access to updated versions of the metabolic and non-metabolic models, which were recently generated by Path2Models. One of the changes to those models is the fact that experimentally-determined rate laws and parameter values were retrieve from SABIO-RK and incorporated into the models.

Graphical representations of the metabolic models are now available. Those follow the SBGN standard and are available in two formats (PNG and SBGN-ML) and can be downloaded from the "additional files" menu.

Finally, now only one version of the SBML files is provided for each model: SBML L3 Core for metabolic models and SBML L3 Core + Qual for non-metabolic models.


Building on the work of the RICORDO project, an early RDF/XML conversion of SBML models has been developed. One of the long term aim is to make all models available in a triple store, readily accessible for Semantic Web applications.

At this stage, only RDF/XML versions of the models published in the literature were created. All generated files are available in a dedicated archive on the FTP server.

The SBML to RDF/XML converter developed is hosted on GitHub, as well as some documentation.

We are calling for feedbacks regarding the RDF/XML files produced. Please refer to the contact page for means to provide us with your comments.

This is an on-going work, so the RDF might evolve in subsequent releases.

SBML files with URLs

As announced previously, all SBML files provided for download now contain, by default, annotations making use of URLs. The possibility to download the models with annotations using the old MIRIAM URNs is still available via the download menu as well as in the archives.

Caltech mirror

The content of the Caltech mirror will be updated in the forthcoming days.


All the models of this release are provided in the followning archives from our FTP server:
