OpenTransSharp and BMEcatSharp

About This Project

This project enables reading, editing, writing and validating openTRANS® 2.1 and BMEcat® 2005 files. While developing, your IntelliSense is enriched with contents of the official specification-documents. It also provides seamless integration into Microsoft.Extensions.DependencyInjection and ASP.NET Core.

This project is built on the .NET platform and uses the MPL 2.0 license (see MPL 2.0 TLDR; for what that means for you).

Usage

Reading

Here are 3 ways of reading a openTRANS®-document in ASP.NET Core:

Note: for BMEcat®-documents, it works the same way, but using IBMEcatXmlSerializerFactory instead of IOpenTransXmlSerializerFactory.

...
using OpenTransSharp;
using OpenTransSharp.Validation;
using OpenTransSharp.Xml;
...
[ApiController]
[Route("[controller]")]
public class ValidationController : ControllerBase
{
    private readonly IOpenTransXmlSerializerFactory serializerFactory;

    public ValidationController(IOpenTransXmlSerializerFactory serializerFactory)
    {
        this.serializerFactory = serializerFactory ?? throw new ArgumentNullException(nameof(serializerFactory));
    }

    [HttpPost("via-model-binding")]
    public void ViaModelBinding(Order order)
    {
        // validation implicitly by model binder
    }

    [HttpPost("via-stream")]
    public void ViaStream()
    {
        var serializer = serializerFactory.Create<Order>();

        using var stream = Request.BodyReader.AsStream();
        var document = serializer.Deserialize<Order>(stream);

        document.EnsureValid(serializer);
        // or manually validate your document
        //var validationResult = document.Validate(serializer);
    }

    [HttpPost("via-file")]
    public void ViaFile(IFormFile file)
    {
        var serializer = serializerFactory.Create<Order>();

        var stream = file.OpenReadStream();
        var document = serializer.Deserialize<Order>(stream);

        document.EnsureValid(serializer);
    }
}

Editing and Writing

openTRANS®- and BMEcat®-documents can be easily modelled like any other C# Type.

Rich IntelliSense helps you building the documents in the right, valid way, be leveraging the content of the specifications.

using OpenTransSharp;
using OpenTransSharp.Xml;
...
var serializer = serializerFactory.Create<Order>();

var document = new Order()
{
	Type = OrderType.Express    
}
document.Header = new OrderHeader
{
    ControlInformation = new ControlInformation
    {
        GenerationDate = DateTime.UtcNow,
        GeneratorInfo = "Demo"
    },
    SourcingInformation = new SourcingInformation { ... }
    ...
};
document.Items.Add(new OrderItem
{
    LineItemId = "1",
    ProductId = new ProductId 
    { 
        SupplierPid = new SupplierPid("A0123456789", SupplierPidTypeValues.Ean);    
    },
    Quantity = 2,
    OrderUnit = PackageUnit.C62, // pieces
    ...
});

var serializedString = serializer.Serialize(document);

Validation

You can validate all root-documents like BMEcatDocument, Order, Invoice,... against the official XSDs - without having to fiddle with them. Validation is easy with the provided Validate extensions method.

You can manually validate you documents like this:

using OpenTransSharp;
using OpenTransSharp.Validation;
using OpenTransSharp.Xml;
// if you want to validate BMEcat® documents use the following namespaces:
//using BMEcatSharp;
//using BMEcatSharp.Validation;
//using BMEcatSharp.Xml;
...
var validationResult = order.Validate(serializer);

if (!validationResult.IsValid)
{
    foreach(var error in validationResult.Errors)
    {
    	foreach(var message in error.Value)
        {
            Console.WriteLine($"{error.Key}: {message}");
        }
    }
}

Or you can just call EnsureValid, which throws a OpenTransSharp.Validation.ValidationException if not valid:

order.EnsureValid(serializer);

Setup Your Project

BMEcatSharp and OpenTransSharp can be used in any .NET Standard 2.0 compatible or .NET 6+ project.

Note: For complete samples of how to use this library, please see the code samples in this repository under

• BMEcatSharp.Samples.AspNetCore and
• OpenTransSharp.Samples.AspNetCore

NuGet Packages

Depending on the desired integrations, you can pick 1 of 3 options:

A) If you want to integrate with ASP.NET Core, you can use the following NuGet packages:

• BMEcatSharp.Microsoft.AspNetCore
• OpenTransSharp.Microsoft.AspNetCore

Note: You need both if you want to read/edit/write/validate BMEcat®- and openTRANS®-documents in your project.

B) Otherwise, if you only want to integrate with Microsoft.Extensions.DependencyInjection, you can use the following NuGet packages:

• BMEcatSharp.Microsoft.Extensions.DependencyInjection
• OpenTransSharp.Microsoft.Extensions.DependencyInjection

Note: You need both if you want to read/edit/write/validate BMEcat®- and openTRANS®-documents in your project.

C) And finally, if you don't need any of the above integrations but only core funcationality, you can use the following NuGet packages:

• BMEcatSharp - if you only need BMEcatSharp
• OpenTransSharp - if you need OpenTransSharp (has a dependency on BMEcatSharp)

ASP.NET Core Setup

Registering the ASP.NET Core integrations as shown here. These integrations add input formatters for model-binding and model-state handling.

OpenTransSharp

public void ConfigureServices(IServiceCollection services)
{
    services.AddOpenTransSharp(configure =>
    {
        // optional: register your custom UDX (user defined extension) types here
        configure.Serialization.IncludeUdxTypes = new[]
        {
            typeof(CustomData),
            typeof(CustomData2)
        };

        // optional: add custom xsd for validation
        configure.Serialization.XsdUris = new[] { new Uri($"file://{Environment.CurrentDirectory.Replace("\\", "/")}/CustomData.xsd") };

        // optional: add xml-file encodings that must be supported
        configure.Serialization.SupportedEncodings.Add("iso-8859-1");

        // optional: add xml-file content types that must be supported
        configure.Serialization.SupportedMediaTypes.Add("text/xml");

        // optional: if you need more control here the overrides can be customized
        configure.Serialization.ConfigureXmlAttributeOverrides = overrides =>
        {
            // add overrides
        };
    });
    services.AddControllers()
        // register for proper serialization over API
        .AddOpenTransSharpXmlSerializer();
    ...
}

BMEcatSharp

public void ConfigureServices(IServiceCollection services)
{
    services.AddBMEcatSharp(configure =>
    {
        // optional: register your custom UDX (user defined extension) types here
        configure.Serialization.IncludeUdxTypes = new[]
        {
            typeof(CustomData),
            typeof(CustomData2)
        };

        // optional: add custom xsd for validation
        configure.Serialization.XsdUris = new[] { new Uri($"file://{Environment.CurrentDirectory.Replace("\\", "/")}/CustomData.xsd") };

        // optional: add xml-file encodings that must be supported
        configure.Serialization.SupportedEncodings.Add("iso-8859-1");

        // optional: add xml-file content types that must be supported
        configure.Serialization.SupportedMediaTypes.Add("text/xml");

        // optional: if you need more control here the overrides can be customized
        configure.Serialization.ConfigureXmlAttributeOverrides = overrides =>
        {
            // add overrides
        };
    });
    services.AddControllers()
        // register for proper serialization over API
        .AddBMEcatSharpXmlSerializer();
    ...
}

Microsoft.Extensions.DependencyInjection Setup

If don't need ASP.NET Core but Microsoft.Extensions.DependencyInjection integration, the previous sample sections calling

• services.AddBMEcatSharp(...) respectively
• services.AddOpenTransSharp(...)

are the actual Microsoft.Extensions.DependencyInjection integration.

Core Functionality Setup

If you don't need any integrations, you can just simply use the core functionality.

BMEcatSharp

using BMEcatSharp;
...
var options = new BMEcatXmlSerializerOptions();
var serializerFactory = new BMEcatXmlSerializerFactory(options);
// from here on see previous usage examples

OpenTransSharp

using OpenTransSharp;
...
var options = new OpenTransXmlSerializerOptions();
var serializerFactory = new OpenTransXmlSerializerFactory(options);
// from here on see previous usage examples
