The Facets library allows you to describe and make instances of Faceted Contexts. These are interfaces decorated with facet attributes.

public interface IDataContext : IContext
{
    [DataStore, RootPath(TestRootPath), JsonSerialization, GZipCompression]
    IDataStore<string> DataStore { get; }
}

These contexts are descriptive and implementationless at design time.

Component authors create facet attributes (such as the DataStoreAttribute, RootPathAttribute, etc. above) that allow facets of their components to be composed at runtime.

You can use a ContextFactory to create an instance of a context at runtime.

var context = new ContextFactory().Create<IDataContext>();

Facets can be used with Data Stores to create DRY, descriptive, implementationless data contexts.
