Handling Complex vCard Features 5.1 Groups and Multiple Entries vCard supports grouping (e.g., item1.EMAIL;TYPE=work ). A robust converter must parse the group prefix and reconstruct it in JSON, usually as nested objects. 5.2 Binary Data (Photos/Logos) vCard can embed base64-encoded images ( PHOTO;ENCODING=b;TYPE=JPEG:... ). Convert to JSON as a base64 string and optionally decode to a URL or file reference. 5.3 Custom Properties (X- extensions) Properties like X-ABUID (Apple Address Book UID) should be preserved in JSON under a custom or x-properties object. 5.4 Multi-line Values (Folded Lines) vCard 3.0 uses folding: a line starting with a space or tab continues the previous property. A parser must unfold these before processing. Handling Complex vCard Features 5
