About 18 months ago, I asked: Do you teach or educate?
I continue to use and develop emacs-reveal, a FLOSS bundle to create HTML presentations based on reveal.js as Open Educational Resources (OER) from Org mode source files in GNU Emacs. Last time, I mentioned license attribution for OER figures as tedious challenge, which I believe to be addressed properly in emacs-reveal.
Over the last couple of days, I added functionality that generates license information in my OER HTML presentations from SPDX headers embedded in source files. The FSFE project REUSE recommends the use of SPDX headers to indicate copyright and licensing information in free software projects, and, although OER are not software, I started to make my OER source files REUSE compliant. Thus, the following two simple header lines in an Org source file (e.g., the emacs-reveal howto)
#+SPDX-FileCopyrightText: 2017-2020 Jens Lechtenbörger <https://lechten.gitlab.io/#me> #+SPDX-License-Identifier: CC-BY-SA-4.0
result in the following HTML licensing information (as part of the final slide in the howto) with RDFa markup for machine readability:
<div class="rdfa-license" about="https://oer.gitlab.io/emacs-reveal-howto/howto.html">
<p>Except where otherwise noted, the work

Previously, I created the slide with license information separately, without taking copyright and license information of source files into account. Clearly, that type of redundancy was a Bad Thing, which I got rid of now. And, since license information is generated (currently in English or German based on the document’s language), you as future users of emacs-reveal do not need to know anything about RDFa (and next to nothing about HTML).
Happy New Year to all of you!
