Is there a standard file naming convention for key-value pairs in filename?

Question

I have multiple data files that are named after what they contain. For example

machine-testM_pid-1234_key1-value1.log

There are keys and values separated by - and _. Is there a better syntax for this? Are there parsers that automatically read these kinds of files/filenames?

The idea here is that the filenames are human and machine readable.

Answer 1

There seems to be no standard file naming convention for key-values.
