The ITER Integrated Modelling & Analysis Suite (IMAS) is the software infrastructure being developed using expertise from across the research institutes within the ITER Members to meet the needs of the ITER Integrated Modelling Programme. It builds around a standardised representation of data described by a Data Dictionary that is both machine independent and extensible. Machine independence is important for allowing tools developed in IMAS to be tested on existing devices, whilst extensibility allows the Data Dictionary to grow and evolve over time as more and more Use Cases are addressed. In addition to providing all the scientific tools for the exploitation of ITER once operations start, IMAS also has a role to play during the construction phase by providing simulation data to support systems design, in particular for diagnostics, heating, fuelling and control systems. An IMAS workflow developed from the DINA and JINTRAC code suites and coupling the transport across the core, edge and SOL regions has now, for the first time, performed simulations of the 15 MA / 5.3 T Q=10 DT ITER baseline scenario from the X-point formation during ramp-up to the X-point to limiter transition in the ramp-down. Recently an IMAS database of ITER simulations has started to be developed to help manage the exchange of data with ITER collaborators and Domestic Agencies. The database is being populated by translating existing data and running new simulations. The codes used to initially populate the database are ASTRA, CORSICA, DINA, JINTRAC, and METIS. Additional data structures consistently describing other aspects of the scenarios are being added to the database upon request. Scenarios for all stages of the ITER Research Plan are represented in the database which is accessible to all ITER contributors through the IMAS Access Layer, either for visualisation or as input to IMAS-adapted workflows and codes.
