Introduction¶

The IMAS Data Dictionary (DD) defines the standardized data structures used for IMAS data.

IMAS overview¶

IMAS is the Integrated Modeling and Analysis Suite of ITER. It consists of numerous infrastructure components, physics components and tools. An up-to-date overview of these can be found at https://imas.iter.org/ (ITER Organization account required).

The IMAS core consists of:

1. Standardized data structures for storing experimental and simulation data.

2. Infrastructure for storing and loading these data structures.

Data dictionary¶

The standardized data structures are defined in the Data Dictionary, of which you are currently reading the documentation. The DD defines, for example:

• Which data structures (IDSs) exist

• What data is contained in these structures

• What units a data field has

• What are the coordinates belonging to a data field

Access layer¶

The Access Layer provides the libraries for working with these data structures, for example:

• Loading an IDS from disk

• Storing an IDS to disk

• Using and manipulating IDSs in your program

The Access Layer has interfaces for the following programming languages. Click on the link to go to the respective documentation pages:

• Python

• C++

• Fortran

• Java

• MATLAB
