Description
Type
Metadata Access.
Behaviour
It shows metadata information about a datacube and the dimensions related to it.
Parameters
- cube: name of the input datacube. The name must be in PID format.
- action : command type; use
- “read” to access information (default)
- “add” to add a new dimension. Dimension size will be 1
- “clear” to delete collapsed dimensions.
- level: In case of action “read”, level of information shown.
- 0: shows only metadata (default)
- 1: shows only dimension values
- 2: shows metadata and dimension values.
- dim: names of dimensions to show. Valid with level bigger than 0 only. In case of action “read”, all dimension are shown by default and multiple values can be set (separated by “|”). In case of action “add”, only one dimension has to be set.
- show_index: if “no” (default), it won’t show dimension ids. With “yes”, it will also show the dimension id next to the value.
- show_time: if “no” (default), the values of time dimension are shown as numbers. With “yes”, the values are converted as a string with date and time.
- base64: if “no” (default), dimension values are returned as strings (with possible trucantion errors). With “yes”, raw dimension values are returned as base64-coded strings.
- concept_level: concept level short name (must be a single char) of the new dimension. Default value is “c”.
- dim_level: level of the new dimension to be added in dimension table.
- dim_array: use “yes” to add an implicit dimension (default), use “no” to add an explicit dimension.
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, cubeschema_cubeinfo => shows cube information as grid, cubeschema_morecubeinfo => shows more cube information as grid cubeschema_diminfo => shows the list of cube dimensions as grid, cubeschema_dimvalues => shows the values of cube dimensions as grid).
Examples
Show metadata information about the datacube identified by the PID “URL/1/1”:
[OPH_TERM] >> oph_cubeschema cube=URL/1/1;
