Request for Information: negative values extracted by JHOVE

[asciim0]

With the recent change in JHOVE 1.34 reporting some pdf number of objects as -1 (see also #1088) we discoved in our Rosetta-JHOVE integration that we omitted -1 as an extracted property. I suspect this is because we considered it to be an error code.

Hence my question:
Are negative values including -1 acceptable values for extracted properties accross all modules? Is there a simple overview somewhere which includes data types for all extractable properties?

We'll update the integration to accept -1 as a value, however, it would be helpful to know which extracted values we may have missed in the meantime.

Hi @asciim0, this is similar to #1088. Again I will take a look and report back to you.
