Metadata Access.


It shows some information about a container: description, vocabulary, dimension list, etc.


  • container: name of the input container.
  • cwd: absolute path corresponding to the current working directory.

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, containerschema => shows operator’s output PID as text).
