I'm requesting a TAG review of IMSC 1.2 FPWD, specifically the delta relative to IMSC 1.1, of which the main substantive change is the addition of support for the #font feature.
This feature allows the content author to specify an external font resource to be used when presenting the document, with attributes similar to the descriptors that can be specified with the CSS @font-face rule.
Security and Privacy self-review²: This is largely unchanged since IMSC 1.1 however note the privacy review issue raised against TTML2, from which some new features are referenced, at w3c/ttml2#1189 See also w3c/imsc#503
Organization(s)/project(s) driving the specification: [organization and/or project name]
Key pieces of existing multi-stakeholder review or discussion of this specification:
External status/issue trackers for this specification (publicly visible, e.g. Chrome Status): None
Further details:
I have reviewed the TAG's API Design Principlesbut it is not relevant since this is not an API specification
Relevant time constraints or deadlines: we would appreciate an expedited review of this small delta please.
The group where the work on this specification is being done: W3C TTWG
Major unresolved issues with or opposition to this specification: None
This work is being funded by: TTWG group participants
You should also know that...
The FPWD was published on 2019-11-28 and the feature delta is small.
The main substantive requirement was to allow inline images such as company logos to be inserted into text. By allowing external font resources to be specified, the subtitle or captions document author can have some reassurance that the desired image is present in the selected font. Two image mechanisms are feasible: 1. A fallback image in the font file, e.g. the text "W3C" might be replaced inline with an SVG image of the W3C logo; 2. The Unicode private use area of code points can be used to define bespoke images.
We'd prefer the TAG provide feedback as (please delete all but the desired option):
