The Physiome Knowledgebase (PKB) is a searchable and linkable assemblage of annotated computational models and data being developed for use within the VPR community. The concept behind the PKB is to make available all data and models developed within the VPR to those working on the various projects. The information contained within the PKB will include unambiguous semantic identifiers that aid in the understanding of the system being modeled or the experimental dataset, facilitate model merging, reuse and submodel extraction, and foster the linking of experimental data to appropriate computational models. The PKB while initially developed for the VPR community is extensible to include models and data from outside repositories and to be used by the larger scientific community.
