- Collaborative workspace: user interface for the risk assessors: describing risk assessments and variables, using the principles of mass collaboration (a large group of interested people working together for a common goal) and argumentation (rules for resolving disputes using structured argumentation). The collaborative workspace contains four kinds of information:
- Openly available and usable, structured information. This is mainly in the form of variables.
- Openly available and usable, but freely structured information. The major part of this content is in the form of an encyclopedia and glossary, but there are also fact sheets, guidance documents, and data and models there.
- There can also be structured information as variables that have a limited access. This may be the case in some so called private risk assessments, where the needs of confidentiality are stronger than the benefits of mass collaboration.
- There can be metadata about the data existing in external sources, i.e. data that is not openly available and usable and is not structured as variables. This metadata is also called the Data gateway.
- Separate calculation tools: a functionality to transform variable definitions into a model that can compute results using an external software, such as Analytica or R.
- External models: If a variable requires complex computing (such as atmospheric modelling), the actual definition can be externalized to a collaborating institute. The institute runs the model, and only the result is made available in the result database.
- Result database: contains previously calculated results of variables, so that they are available for risk assessments and for calculating downstream variables.
- Analysis tool: This tool performs the assessment-specific analyses, such as scenario optimising, sensitivity analyses, or value-of-information analyses. (Assessment-specific means that the analysis is not a part of any single variable but is an analysis about a group of variables within an assessment.) These analyses are based on the result database.
