The ITER Integrated Modelling & Analysis Suite (IMAS) is the software infrastructure developed using expertise from across the research facilities 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 and workflows 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 scientific 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. This aligns well with one of the primary simulation capabilities that IMAS needs to deliver, namely end-to-end simulations of ITER plasma scenarios capable of meeting the physics fidelity and runtime requirements of different Use Cases, including scenario design, PCS controller development and pulse validation. An IMAS database of ITER simulations has been created to help manage the exchange of physics data with ITER collaborators and Domestic Agencies. The database is being populated through a combination of translating existing data and running new simulations, with datasets representing all stages of the ITER Research Plan already available. In preparation for ITER operations, near-term plans include the development of experimental data processing and analysis pipelines. This activity will build upon the experience and best practices developed within the R&D facilities of the ITER Members. Whilst the detailed implementation of the processes for combining diagnostic contributions and validating the measurements is yet to begin, the need for a strictly managed, yet flexible, process is recognised, and infrastructure developments are conducted bearing this in mind.
