- The emergence of biological pathway datasets in BioPAX format provides a standard way to exchange pathway datasets and new ways to explore and navigate biological data. The lack of a searchable, centralized repository of the BioPAX datasets poses a challenge in integrating internal and external data elements. We have designed a system which uses an XML database along with a layer of adaptors to link internal and external data elements, facilitating the automated navigation of biological data for biomedical research.
