ITER Physics Data Model Documentation for cryostat

Description of the cryostat surrounding the machine (if any)

Notation of array of structure indices: itime indicates a time index; i1, i2, i3, ... indicate other indices with their depth in the IDS. This notation clarifies the path of a given node, but should not be used to compare indices of different nodes (they may have different meanings).

ids_properties/comment Any comment describing the content of this IDS {constant} STR_0D
ids_properties/name User-defined name for this IDS occurrence {constant}. Introduced after DD version 3.39.0 STR_0D
ids_properties/homogeneous_time This node must be filled (with 0, 1, or 2) for the IDS to be valid. If 1, the time of this IDS is homogeneous, i.e. the time values for this IDS are stored in the time node just below the root of this IDS. If 0, the time values are stored in the various time fields at lower levels in the tree. In the case only constant or static nodes are filled within the IDS, homogeneous_time must be set to 2 {constant} INT_0D

ids_properties/provenance/node(i1)/reference(i2) List of references used to populate or calculate this node, identified as explained below. In case the node is the result of of a calculation / data processing, the reference is an input to the process described in the "code" structure at the root of the IDS. The reference can be an IDS (identified by a URI or a persitent identifier, see syntax in the link below) or non-IDS data imported directly from an non-IMAS database (identified by the command used to import the reference, or the persistent identifier of the data reference). Often data are obtained by a chain of processes, however only the last process input are recorded here. The full chain of provenance has then to be reconstructed recursively from the provenance information contained in the data references. Click here for further documentation..
