This project aims at deprecating jCard in RDAP.
According to the feedback from RDAP Pilot WG, the most frequent concern about RDAP implementation at both server and client side is currently related to the handling of jCard. In fact, it is considered:
- unintuitive;
- very complicated for both consumers and servers;
- uncompliant with REST API standards;
- affecting performance.
Such a feeling is not limited to RDAP implementers but is also shared by most of APIs producers and consumers dealing with jCard. JSContact includes a contact representation that is able to represent the same information as jCard more efficiently. In particular, it meets the requirements from RDAP implementers about representing multilingual information and unstructured data. Therefore, jCard might be deprecated and replaced by the contact card defined by JSContact in the RDAP responses.
While the jCard element in the RDAP response is named "vcardArray", its JSCard counterpart is called "jscard" to be compliant with the extension identifier defined in the rdapConformance array. Here in the following examples of mapping between "vcardArray" and "jscard" according to the policy defined in JSContact: Converting from and to vCard are shown.
