THEN the tool shall print a warning.

IF a list element given through the configuration file under "inputs" is not a file nor a directory,
THEN the tool shall exit with a non-zero return code.

Note: This could happen if a path does not exist.

AND the input items contains that key
THEN the tool SHALL use the value of that key as tag in the serialized LOBSTER item.

TRLC System_requirement_aspect json_req.Name_Attribute_Missing
Source: lobster/tools/json/synthetic_name.trlc:20
OTHERWISE ("name-attribute" is not given or not an empty string), the tool
SHALL create a synthetic tag name based on the path of the JSON input file and an item counter.

Notes:
- "Synthetic" means that, the name does not need to be related to the data.
- The item counter does not need to be unique across input files,
but it shall be unique at least for each input file separately.
- No further specification is made about how to combine the path and the item counter.
