ISO20022.XSD

ISO20022.XSD is a .NET library designed to convert ISO 20022 XSD files into standard JSON format.

This library simplifies the processing and integration of ISO 20022 messages in various applications.

Use Case

using ISO20022.XSD;

var fileInfo = new FileInfo(fileName);
if (File.Exists(fileName) && fileInfo.Extension.Equals(".xsd"))
{
    XsdToJson xsdLib = new(fileName);
    xsdLib.Convert();
    File.AppendAllText(fileInfo.FullName.Replace(".xsd", ".json"), xsdLib.SchemaJson);
}

Model of JSON

public class XsdSchema
{
    public required string Namespace { get; set; }
    public required SchemaElement SchemaElement { get; set; }
}

public class SchemaElement
{
    public string? Id { get; set; }
    public string? Name { get; set; }
    public string? DataType { get; set; }
    public string? MinOccurs { get; set; }
    public string? MaxOccurs { get; set; }
    public string? MinLength { get; set; }
    public string? MaxLength { get; set; }
    public string? Pattern { get; set; }
    public string? FractionDigits { get; set; }
    public string? TotalDigits { get; set; }
    public string? MinInclusive { get; set; }
    public string? MaxInclusive { get; set; }
    public string[]? Values { get; set; }
    public bool IsCurrency { get; set; }
    public string? XPath { get; set; }
    public List<SchemaElement> Elements { get; set; }
}

Example

{
    "namespace": "urn:iso:std:iso:20022:tech:xsd:camt.053.001.10",
    "schemaElement": {
        "id": "Document",
        "name": "Document",
        "dataType": null,
        "minOccurs": "1",
        "maxOccurs": null,
        "minLength": null,
        "maxLength": null,
        "pattern": null,
        "fractionDigits": null,
        "totalDigits": null,
        "minInclusive": null,
        "maxInclusive": null,
        "values": null,
        "isCurrency": false,
        "xpath": "Document",
        "elements":[
          ...
        ]
    }
}

Notes

• Throw JsonException in the case where it found deep nested node structure.
• CurrentDepth (64) is equal to or larger than the maximum allowed depth of (64)
