Hi Guys, Don't know if this is the right area to post this. I'm currently doing up a prototype of a LOB with Asp.net mvc w/HTML5, it will be an offline web application. Everything seems quite doable (other than being 10 times the amount of code) except for the data persistence layer. We require all data persistence to be managed client side, so this means some complex javascript and to do a simple CRUD scenario on a odata service it takes approx. 150 lines (retrieving data is reasonably simple, but when you get to modifying it than it turns into spaghetti code) of code vs 10 lines of code in the equivalent SL or ios platform.
 
My question is, is ideablade looking into creating anything in the future in regards to HTML5 and the entity manager?
 
Looking forward to your response.
 
Thanks

Yes, we are looking at writing a DevForce EntityManager for JavaScript. We're still in the preliminary stages, so I don't have anything to share yet. Until then, you can use OData to query the DevForce server (as you already know).

For those new to OData. Here's the OData tutorial:

This is a simple example querying OData from JavaScript:

This is a sample using Microsoft's RIA/JS with DevForce:
