Goals:

> SCHEMA COURSE EXTENSION COMMUNITY GROUP
>
> This mission of this group, initiated by LRMI, is to develop an extension
for schema.org concerning the discovery of any type of educational course
(online/offline, long/short, scheduled/on-demand). Educational course is
defined as "some sequence of events and/or creative works which aims to
build the knowledge, competence or ability of learners". (Out of scope:
information about students and their progression etc; information needed
internally for course management rather than discovery).

I feel like things get lost in mailing lists [*]; whereas with one issue
thread (and pingbacks), it's much easier to scan the whole discussion

Course
  CourseUnit s
     CourseUnit s
        Thing s


Course
  units = []
  CourseUnit < ThingSequence
     units = []
     CourseUnit < ThingSequence
        things = [CreativeWork_0, CreativeWork_X, Thing_Y]


"Schema.org 101" <Course.name>
   "Unit 1: Linked Data" <CourseUnit.name>
       "Unit 1.1: URLs and URIs" <CourseUnit.name>
           https://example.org/  <Thing.url>


Practically, if one was to write a Course (Course Metadata + Curriculum /
Lesson Plan) with e.g. Markdown and ReStructuredText,

```markdown
# Schema.org 101
## About
* | name:
* | description:
* | url:

## Units
### Unit 1: Linked Data
#### Unit 1.1: URLs and URIs
* https://example.org

```

```restructuredtext
============
Schema.org 101
============
.. contents:
   :local:

About
#######
* | name:
* | description:
* | url:

Units
######

Unit 1: Linked Data
=================

Unit 1.1: URLs and URIs
-------------------------------------
* https://example.org

```

Use case: find courses which reference a schema:Thing.url (e.g. of a
schema:CreativeWork) ["Find courses which frame this content"]
