Step 1 of 9 in Making a new edition
Sample data, read from content-sdk
Starting an edition
One region needs its own Language Arts. Ben starts Language Arts (Regional), an edition of Language Arts.
An edition starts as a copy of what its original has published. Anything not published stays behind.
Try it: select Topic B, then Lesson 1, in either book.
Topic B and Topic C aren't published, so the edition has no rows for them. Everything it does have starts out not published, and Language Arts doesn't change.
