== Overview ==

This proposal is to extend MapGuide Feature Service to support applying schema.

== Motivation ==

Currently MapGuide Web API doesn’t support any functionality to create or modify schema of a feature source. The RFC is used to eliminate this limitation.

== Proposed Solution ==

ApplySchema need not only support adding, modifying but also support deleting schema elements. So we need a method to mark the schema element for deletion. The method Delete() will be added to classes MgFeatureSchema, MgClassDefinition, MgPropertyDefinition for it.

== Implications ==

This is new API only. There will be no effect on existing applications. However, API documentation need to be updated.

== Test Plan ==

Add unit tests for method MgFeatureService::ApplySchema into the existing Feature Service unit tests.

== Funding/Resources ==
