Read a delta from a custom media type formatter... if a bit naughty.

ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<EfContext>("EfContext");
IEdmModel model = builder.GetEdmModel();
var odataFormatters = ODataMediaTypeFormatters.Create(model);
var delta = content.ReadAsAsync(type, odataFormatters).Result;

We have two different kinds of route at present, /Api/{AppId}/{Controller}/{Id} and /Api/{Controller}/{Id}. The Linked route provider ensures that if we PATCH or PUT to either of these that we also invalidate the cache for the same route without the {Id} parameter
View Config
config.MessageHandlers.Add(new CachingHandler
{
UriTrimmer = (uri) => uri.LocalPath,
LinkedRoutePatternProvider = LinkedRoutePatternProvider
});

var appAware = new Regex("/Api/[0-9]+/([a-z]|[A-Z])+/[0-9]+");

Quick sketch of pulling together data required to build nested routes

Very simple example of hierarchical route generation in asp.net web api
View gist:5142264
// Base route
config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}", new { id = RouteParameter.Optional });
// Nested route (must be distinguishable by param names from above) - Deisgnated by leading _
config.Routes.MapHttpRoute("NestedRoute", "_/{controller}/{rootId}");
// Root controller signature:
public class AppDataController : ApiController

Cache invalidation use-case #1
View gist:5244422
I have a URI used to manipulate data records:
http://api/{AppId}/AppData/
There is also the ability to retrieve several report dataviews based on the records.
http://api/{AppId}/ChartData/{chartId}
I need a mechanism so that when I POST to http://api/{AppId}/AppData/, or DELETE\PATCH to http://api/{AppId}/AppData/{id} then any cached route starting with http://api/{AppId}/ChartData/ gets invalidated.

Http routes as state machine
View gist:5310180
The route state machine defined in pseudo code below is able to handle the following routes:
/Api/Products/
/Api/Products/1
/Api/Categories
/Api/Categories/1
/Api/Products/1/Categories
/Api/Products/1/Categories/2
You can’t perform that action at this time.
