These include:

• eval_tool (a string for UI)
• cpu_time
• cer_mean
• cer_median
• cer_range (instead of cer_min_max)
• cer_standard_deviation
• wer
• pages_per_minute

on document level and

• wer

on page level.

I think this information should actually be retrieved from the JSON Schema. I added it here for the time being as long as the schema isn't merged.

The front-end relies on that data in order to display the namings correctly. So for me if would be sufficient to add placeholder strings for now.
