Model Sharing Working Group
Working Group leads: Peter Hunter; Herbert Sauro
Goals and Objectives:
The goals of this working group are to develop and promote: (i) modeling standards, (ii) software for authoring, visualisation and simulation of models, and (iii) model repositories that facilitate model reproducibility and model sharing. The group will provide an interface to international efforts on model sharing by the SBML consortium, the European VPH community, the IUPS Physiome community, the NeuroML project and the synthetic biology data exchange group.

Model Sharing Myths
1. Models are easily reproducible
This is common myth. One takes a model, enters it into a piece of software and the expectation is that one will get the same answer as published in the literature. Not necessarily true. Different tools implement numerical analysis methods differently, random number generators may have bias or different time steps or scale are used resulting in different simulation outcomes.
2. Extracting working models from the literature is trivial
This is a myth perpetrated by those who have never tried to extract a model from a published paper. Experience from the BioModels database project at EBI shows that at least 9 out of 10 of all models curated by EBI cannot be made to work from the published paper itself. This represents a huge waste of resources since models must be painstakingly recreated. One would assume this is especially true for multiscale models which are generally more complex than subcellular models. However no data is available on the creation of multiscale models from the literature.
Developing systematic methods to share models is one way to make the above myths come true. On the one hand standards such as SBML or CellML can be used to unambiguously describe a model but we have currently no way to unambiguously specify how to reproduce the results of simulating a model. It as if an experimentalists had no easy way to reproduce a published experiment.

Challenges and Opportunities:
A specific challenge for this year is to have one or more of the IMAG groups using the existing modeling standards and to understand what the impediments are to wider use of standards by the IMAG community.

- TITLE: The VPH/Physiome model repository
- PRESENTERS: Tommy Yu, Randall Britten and Peter Hunter
- Abstract: Models encoded in the CellML and FieldML formats are stored in a repository called PMR2 (Physiome Model Repository 2). This talk till explain the current features of the repository and its future development. We will also briefly discuss some of the open source software libraries that incorporate the application programming interfaces (APIs) to the model repository.
