What is SDMX.NET?

SDMX is a large and complex standard which makes creating SDMX-capable applications a difficult and error-prone activity. Using an SDMX specific library, which is an accurate implementation of the standard, will enable developers to create robust and production ready SDMX applications. SDMX.NET is that library.‬

• Completely open source.
• Produce and consume SDMX from any data source (like Excel or Database).
• Accurate implementation of the supported SDMX artefacts.
• Written in C# and thus compatible with any .NET application.
• Intuitive and easy to use API.
• Optimized for scalability and performance.

Examples

To give an idea of what the framework can accomplish, here is a code sample in C# for inserting an SDMX file into the database. It is important to note that the library ensures that the resulting dataset is 100% valid based on the key family definition.

// load the structure definition
var structure = StructureMessage.Load("StructureSample.xml");
var keyFamily = structure.KeyFamilies[0];

// create IDataReader from the data file
using (var reader = DataReader.Create("GenericSample.xml", keyFamily))
{
    // use bulk insert into the database
    using (var bulkCopy = new SqlBulkCopy("connection string"))
    {                   
         bulkCopy.DestinationTableName = "TargetTableName";
         bulkCopy.WriteToServer(reader);
    }
}

The DataReader created implements the IDataReader interface and thus can be used like an ADO.NET DataReader that is familiar to .NET programmers.

The following example shows how to create a new code list and save it to a file.

var codelist = new CodeList(new InternationalString(Language.English, "Countries"), "CL_COUNTRY", "UIS");

codelist.Add(new Code("CAN"));
codelist.Add(new Code("USA"));

var message = new StructureMessage();
message.Header = new Header((ID)"MSD_HDR", new Party((ID)"UIS"))
         {
             Prepared = DateTime.Now
         };
message.CodeLists.Add(codelist);

var doc = new XDocument();
message.Save("CL_COUNTRY.xml");

Of course, the framework has many other capabilities like creating other SDMX artefacts and converting between the different data formats.
