OData and Giraffe

OData

OData defines a set of REST APIs based on Entity Data Model. OData Library is a C# based library for working with ODATA and ASP.NET.

Giraffe

Giraffe is a functional, fsharp based micro web framework.

Institis.Giraffe.OData

This is a library to write functional first odata web service. It is possible to write highly compositional OData service.

Examples

Adding EDM model

oDataRoute is a web handler that inserts EDM model into Giraffe. It parses the OData URL and make it available as a ODataRequest in the context available for subsequent web handlers.

    open Institis.Giraffe.OData.Routing

    let model: EdmModel = ...
        GET >=> oDataRoute model >=> handlers 
    ]

Metadata

Once oDataRoute has successfully parsed the path, it is possible to serve metadata by using metadata which matches the OData metadata request, along with metadoc which serializes the EDM to XML.

    GET >=> oDataRoute model >=> choose [
        metadata >=> metadoc
        setStatusCode 500 "Error serializing metadata"
    ]
