[mapguide-users] Adding a new feature class to an already existing feature schema

[Haris Kurtagic]

With Apply schema command you can set whether modifications of schema
will be used (SetIgnoreStates) or schema will be applied as whole.

But there are differences between providers as well as versions of same
provider how they deal with Apply Schema command.

If I remember correctly in Fdo2Fdo new class is added to data store just
by executing apply schema (schema with only new class) against existing
data store.
Also If I remember correctly that didn't worked with SDF if there was
already some data in SDF. But again there were changes in SDF provider.

Subject: [mapguide-users] Adding a new feature class to an already
existingfeature schema


I wondered if anyone knows how to programatically add a new feature
class
definition to an existing feature schema. All the example code I have
goes
on the basis of creating the new class and the schema together in one
step
but I don't have any examples of how to go about retrospectively adding
a
new class to an existing feature schema.

I have so far got to the point of getting hold of an instance of the
feature
service and using the DescribeSchema method to retrieve the schema I
wish to
add to. I can get hold of the schema's class collection and add the new
class to this but I am not sure if that will persist the new feature
class
or if I have to somehow persist the changes to the schema after adding
the
new class to it. 

Has anyone done this / know how it needs to be done?
