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.
