Font metadata is an important topic:

It allows creators to clearly indicate all sorts of useful information about themselves and their foundry or supporting organisation.

There are specific fields for

• Designer
• Designer URL
• Copyright
• License
• License URL
• Manufacturer
• VendorURL

See the dedicated panel in fontforge.

Utilities like otfinfo(1) can show the information. But users will see more and more of this information when handling fonts on their desktop directly.

the Debian fonts task force provides extraction of all that information in its weekly review for all the fonts in Debian.
