Use the OULR21 spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read OULR21 files into TSOULR21 objects. See ediFabric .NET.

ediFabric Native

Native supports X12 today, and HL7 is coming. When it's available, map version 2.6 to this Native model with set_map to parse OULR21 files to JSON from Python, Java, C or C#. See ediFabric Native.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate OULR21 classes in Python, Java, Node.js, Go, Rust or C

The OpenEDI file describes each OULR21 as JSON. To work with OULR21 data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSOULR21. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
