Subject [jira] Commented: (DERBY-2377) Document language based ordering which will be implemented by code related sub-tasks of DERBY-1478.

Daniel John Debrunner commented on DERBY-2377:

> Another topic (or set of topics) that is needed is a
> conceptual topic explaining collation and how it works in Derby. 

Sounds good, getting a definition of what "terrority based" collation actually means is really
needed in the documentation,
especially so app developers can understand how the collation in the database interacts with
other systems that use
that provide collation. Some reference to a standard so that folks can see if the Derby collation
is based upon known algorithms.
The standards most likely be from unicode.org and the SQL standard.

It would be great to figure out if the "terrority based" collation is actually the well-defined
"UNICODE" collation from the SQL standard,
then a well-defined term could be used, "UNICODE" instead of the Derby specific "TERRITORY_BASED".
This would mean Derby's
collation would be well defined by both the SQL and the Unicode standards.

> There is an effort going on to implement language based ordering. This will be implemented
by various code-related subtasks of DERBY-1478. The functional spec is attached to DERBY-1478.
This feature will need accompanying documentation changes and this Jira entry is to track
that work.
