Exactly. Let me amplify that point. The early history of webfonts, when it was a failed technology, consistently mixed up the technical and the legal/licensing aspects. On the one had we had Microsoft's Embedded OpenType (EOT, used by IE4 and up), with a URL embedded in the font for the site that was allowed to use it; the browser was expected to police font usage and not apply fonts to the wrong site. Whether a browser which failed to heed this would be seen as infringing (and liable) under the US DMCA was a significant chilling effect on browser adoption. On the other hand we had Bitstream Portable Font Resource (PFR, used by Netscape 4.x) which was described as being a clean derivation of font rendering and not an actual font, thus not subject to to the font license conditions. This was a hotly disputed claim. There were two attempts to start a W3C working group to standardize EOT. The patented and proprietary technological aspects were by this time openly licensed for RF use. Both attempts failed, due to the legal/licensing aspects. The foundries were still worried about font theft, the browser vendors were still worried about DRM and liability. WebFonts only took off when this decade-long mixing up of technical and legal aspects was replaced by a clean separation. WOFF (and WOFF2) allows (but does not require) a link to a human-readable license. The browser is not required (actually, *is forbidden*) to use the metadata to influence rendering. As a direct result of this, the vast majority of foundries now offer clear, dual (desktop/print and web) licensing. All browsers now support WOFF. WebFont useage on the top 100,000 sites has increased from 2% in 2009 to 50% in 2015. This is clear, compelling evidence that we must not dive into those mistakes of the past. Unlike Leonard, I *am* warning of doom and gloom here and can confidently predict it if we one again follow this erroneous path. The Open Web Platform has eventually suceeded with a WebFonts solution. Digital Publishing is now following the OWP rather than trying to re-invent unnecessary wheels. Thus, this is a solved technical problem for DPub too. > a publisher needs to get the font license that allows them to do > what they need to do.

Agreed. If it turns out that WebFont licenses need to be clarified, extended, or a separate DPub license developed, then foundries will do that. That need not concern this group; it is a legal, licensing, market-driven exercise. -- Best regards, Chris Lilley Technical Director, W3C Interaction Domain
