OPH_CUBEIO

Description

Type

Metadata Access.

Behaviour

It shows the hierarchy of all datacubes used to generate the input datacube and of those derived from it.

Parameters

  • cube: name of the input datacube. The name must be in PID format.
  • branch: it is possible to visualize all datacubes with “all”, only the parent branch with “parent” and only the children branch with “children”.

System parameters

  • exec_mode: operator execution mode. Possible values are async (default) for asynchronous mode, sync for synchronous mode with json-compliant output.
  • ncores: number of parallel processes to be used (min. 1). This operator is not parallel, so the only possible value is 1.
  • sessionid: session identifier used server-side to manage sessions and jobs. Usually, users don’t need to use/modify it, except when it is necessary to create a new session or switch to another one.
  • objkey_filter: filter on the output of the operator written to file (default=all => no filter, none => no output, cubeio => shows cube provenance as a grid, cubeio_graph => shows cube provenance as a directed graph).

Examples

Show the hierarchy of all datacubes used to generate the datacube “URL/1/1” and of those derived from it :

[OPH_TERM] >>  oph_cubeio cube=URL/1/1;branch=all;
