Best approach to design a visual data mapper

[docflied]

Hello all,

 

Need your opinion, advice and orientation.

Currently started a fresh new project involving .NET framework 4.

One of the requirements is to show a GUI letting user doing this :

- Pick a XSD1 and specify the root entity

- Drawing entities and relations in a treeview fashion, one side

- Pick another XSD2 and specify the root entity

- Drawing entities and relations in a treeview fashion, onther side

- User draw visual lines to create and manage mapping rules to be executed once a XSD1 compliant payload is processed in order to produce a XSD2 compliant one

 

For those who know about MapForce, something like it but not so advanced.

 

Trying to convince PL to rely on third party tools (like MapForce) but... in case we should do this from scratch, any experience feedback from someone whom have had to do something similar will be greatly appreciated.

 

When I am saying from scratch, I mean using .NET advanced libraries or packages (EF ? May I use programatically one of several designers used by VS, ...)

 

Thanks in advance
