Hi all,

Going through the specs again for a new course, I was checking the version control. Since "merge" of two branched versions is possible, shouldn't the openEHR terminology include a "merge" value for change_type?

Or a merge is considered to be a "creation" change type with "is_merged" = true?

Ref: page 13 [http://www.openehr.org/releases/1.0.2/architecture/terminology.pdf](http://www.openehr.org/releases/1.0.2/architecture/terminology.pdf)

Thanks!
