== Overview ==

Commercial tiled map layers can be used as base layers within MapGuide flexible layouts. Users can use MapGuide overlays with commercial map service layers(Google maps, Yahoo maps and Virtual Earth).

== Motivation ==

Fusion provide a solution to integrate the commercial map services into standard template: [[BR]]

1. Add some script tags to index.html manually. These scripts indicate commercial mapping api providers and unique api keys supplied by these providers.[[BR]]

2. Modify the application definition to include the commercial map service layers. [[BR]]


MapGuide templates should have the capability to support the commercial map services too, and we also need to provide a more convenient approach to add scripts.

== Proposed Solution ==

1. Save the commercial mapping api providers and keys as extension in application definition.[[BR]]

2. MapGuide templates load the extension information from the application definition , and add the script tags into index.html on demand. [[BR]]

So users just need to provide an application definition with extension, then they will obtain the commercial mapping services. 

== Implications ==

Just add a script tag into index.html of MapGuide templates, which used for loading extension information from application definition. [[BR]]
For those application definitions which do not have extenstion information, there's no additional burden.

== Test Plan ==

Test 5 MapGuide templates(aqua, limegold, maroon, slate and turquoiseyellow) to verify if they could support the commercial map services. 

== Funding/Resources ==
