Description: OpenType Table
Table Class: Other, possibly evolving to Required
Tag: PERM
Name: Permissions and Recommendations
Introduction: This table gives licensees and users global information about the permissions for which the font is licensed and global and specific recommendations about the fonts best uses dynamic to the permissions if required.
Background: In 2006, the W3C released a recommendation for font linking, the @font-face command of CSS; pointing by file name from the css via the W3C UA which finds, downloads and installs the font software to each end-user’s machine from a remote server identified by URL along with the font file name. The font software, in part or whole, is installed in the OS and used to display the type on web page(s) of a site on the end users screen.
