Exchange Standards

Standards to facilitate seamless exchange

A unified Model Description Language (MDL) has been developed. It has been designed to be easily read and written by modellers. It is expected that it will facilitate easy uptake by modellers already experienced in other modelling languages.

The XML-based Pharmacometrics Markup Language (PharmML) a new exchange format for encoding of models, associated tasks and their annotation as used in pharmacometrics.

Its connected metadata framework is based on standard reference ontologies, build on existing community exchange protocols such as the CDISC clinical data standards and CSHARE framework.

The Standard Output (SO) has been developed as a tool-independent exchange XML-based format for storing results in standardised form. It enables effective data exchange within complex workflows as well as supports users in assessing, reviewing and reporting modelling steps.
