OSLC4Net, an OSLC SDK for dotnet

OSLC4Net is an SDK and sample applications that help the .NET community adopt Open Services for Lifecycle Collaboration (OSLC, homepage) and build OSLC-conformant tools.

The SDK allows developers to create OSLC servers and clients by adding OSLC annotations to .NET objects to represent them as OSLC resources. It includes a library based on the dotNetRDF package, which assists with representing these resources as RDF and helps parse Turle, RDF/XML, and JSON-LD documents into OSLC .NET objects.

The OSLC4Net.Client package can be used to help create consumer REST requests. On the server side, the project offers an RDF-specific MediaTypeFormatter that can help process OSLC REST requests within an ASP.NET MVC 5 API (ASP.NET Core 8+ migration is ongoing).

Getting started

If you do not have a .NET development environment, start by downloading VS Code C# Dev Kit. Make sure to install .NET 8 SDK for development. Libraries target NETStandard 2.0/2.1 and should run on .NET 6+.

A simple OSLC Client

Create a new console application targeting .NET 6+, add a NuGet dependency to OSLC4Net.Client and add the following code:

var oslcClient = OslcClient.ForBasicAuth(username, password);

var resourceUri =
    "https://jazz.net/sandbox01-ccm/resource/itemName/com.ibm.team.workitem.WorkItem/1300";
OslcResponse<ChangeRequest> response = await oslcClient.GetResourceAsync<ChangeRequest>(resourceUri);
if (response.Resource is not null)
{
    ChangeRequest wi1300 = response.Resource;
    logger.LogInformation($"{wi1300.GetShortTitle()} {wi1300.GetTitle()}");
}
else
{
    logger.LogError("Something went wrong: {} {}", (response.StatusCode as int?) ?? -1,
        response.ResponseMessage?.ReasonPhrase);
}

Replace resourceUri with a valid OSLC resource URI. This should give you a valid response. See full example project for more details.

[!TIP]

Use https://github.com/oslc-op/refimpl to quickly run a few conformant OSLC servers.

OSLC Server support

Server parts of the SDK have not yet been migrated from .NET Framework to .NET 8+.
