ISO 8583:2023 Datasets in jPOS
· 5 min read
Since ISO 8583:2003, the standard has defined three types of data elements: primitive, constructed, and composite. Primitive and constructed fields have always had first-class support in jPOS. The third type—composite fields—has historically been treated as opaque binary blobs, with application code responsible for parsing their contents manually.
jPOS 3.0.2 changes that.
