Requirements for the work• Reproducible – requires an unambiguous description of
what is done with which model, or set of models, in order to produce some output(s).
• Reusable – requires a detailed description of the work:– physiology/anatomy being modelled;– simulation experiments being performed (numerical
methods, pre-/post-processing, etc.);– cross-references/linked data;– provenance.
• Accessible – non-specialists should be able to reproduce and reuse the work.

Requirements for the work• Reproducible
– CellML (http://cellml.org)– SED-ML (http://sed-ml.org)
• Reusable– RDF/XML, ontologies & knowledgebases– Semantic web technologies– RICORDO (http://www.ricordo.eu/)
• Accessible– Web-based graphical interface

Objective• To provide a user-focused tool for investigations of
epithelial transport from molecular mechanisms through to whole cell models.
• Libraries of existing mathematical models and simulation experiments will be made available to users for the:– investigation/application of previous studies;– development of new studies based on previous work;– validation of new or existing work with new
experimental data or computational tools.

Existing model library• The Physiome Repository contains several
demonstrations of epithelial transport models encoded in CellML.
• See http://models.physiomeproject.org/exposure/42 for some examples.
• These, and other, models are being decomposed into re-usable modules that both use and help develop best-practice guidelines for the CellML community.

The GET framework• All code will be open-source and we currently have the
following parts to the framework.• get-creator: a tool for assembling CellML models of
epithelial transport based on biological annotations.• get-simulator: a SED-ML client tool for the simulation
of epithelial cell models.• get-model-server: prototype web-services for GET.• get-web-application: the web-based graphical user
interface.• GET model repository: test/demonstration models and
simulation experiments.• CSim: a CellML simulation tool.

Bringing in all together• Integrate all the previous tools into a common
framework/environment and make it freely available.• A purely web-based solution is best, but cross-platform
is probably good enough for now.• Make use of standards and public repositories wherever
possible.
• and now for a live demonstration…
