The problem is the following, consider that several different professors/universities/... want to create Linear Algebra books.

We need to host them under different URLs. How should the naming scheme look like?

### Option 1: Incremental numbers

Example URLs:

- http://en.wikitolearn.org/Course:Linear_algebra_1
- http://en.wikitolearn.org/Course:Linear_algebra_2
- http://en.wikitolearn.org/Course:Linear_algebra_3/Bases/Vector_bases

Criticism:

- A number may look like a "level"

### Option 2: Incremental letters

Example URLs:

- http://en.wikitolearn.org/Course:Linear_algebra_a
- http://en.wikitolearn.org/Course:Linear_algebra_b
- http://en.wikitolearn.org/Course:Linear_algebra_c/Bases/Vector_bases

Criticism:

- A letter may look like a "level"

### Option 3: Random (structured) ID

With structure <number><letter><number><letter>

Example URLs:

- http://en.wikitolearn.org/Course:Linear_algebra-2k4h
- http://en.wikitolearn.org/Course:Linear_algebra-7o1t
- http://en.wikitolearn.org/Course:Linear_algebra-6v2k/Bases/Vector_bases

Criticism:

- Diminishes the beauty of nice URLs

### Option 4: Inverse random (structured) ID

With structure <number><letter><number><letter>

Example URLs:

- http://en.wikitolearn.org/Course:2k4h-Linear_algebra
- http://en.wikitolearn.org/Course:7o1t-Linear_algebra
- http://en.wikitolearn.org/Course:6v2k-Linear_algebra/Bases/Vector_bases

Criticism:

- Diminishes the beauty of nice URLs

### Option 5: Some how meaningful IDs

The idea is to add some meaningful IDs, depending on the kind of course.

For courses created on the wiki itself, use the name without ID. If more than one course are created collaboratively, they should differ in name, i.e.

- http://en.wikitolearn.org/Course:Linear_algebra
- http://en.wikitolearn.org/Course:Linear_algebra_by_examples
- http://en.wikitolearn.org/Course:Linear_algebra_for_physicists

Imported books may keep their old name with a I<n> suffix. So:

- http://en.wikitolearn.org/Course:Linear_algebra_I1
- http://en.wikitolearn.org/Course:Linear_algebra_I2
- ...

In the *highly* unlikely event of a clash in the name of wiki-born courses, we'll use the C<n> suffix
