.SH "NAME"
MojoMojo::Schema::Result::PageVersion \- Versioned page metadata
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This table implements versioning of page metadata (not content, see
MojoMojo::Schema::Result::Content for that). It has a composite
primary key \f(CW\*(C`(page, version)\*(C'\fR.
.PP
When renaming a page, a new version is created in this table, with
\&\f(CW\*(C`version\*(C'\fR set to 1 + the maximum version for that \f(CW\*(C`page\*(C'\fR. The
\&\f(CW\*(C`status\*(C'\fR of the new \f(CW\*(C`page_version\*(C'\fR is set to \*(L"released\*(R", its 
\&\f(CW\*(C`release_date\*(C'\fR is set to \f(CW\*(C`DateTime\->now\*(C'\fR, while the old
\&\f(CW\*(C`page_version\*(C'\fR's status is set to 'removed' and its \f(CW\*(C`remove_date\*(C'\fR
is set to \f(CW\*(C`DateTime\->now\*(C'\fR.

document the relationships
.IP "\(bu" 4
in order to support proper rollback, meaning creating a new
version for the rollback operation itself, a \f(CW\*(C`content_version\*(C'\fR
field needs to be added.
.IP "\(bu" 4
\&\f(CW\*(C`created\*(C'\fR is apparently unused: set to 0 for pages populated when
creating the database, and \s-1NULL\s0 for all normal pages.
