The suggestion at that page defined new terms for various VCARD 
properties. For example, "postal-code" becomes "postalCode". (Yes, I do 
realise that hyphenated names are more difficult to use as JSON keys in 

There is no pattern to how these new terms are defined. e.g. the example 
above drops the hyphen and adopts camelCase, but "given-name" apparently 
becomes "given", and "adr" becomes "address". With these inconsistencies 
in naming, the only way an author could implement jCard would be if there 
was a full table mapping between hCard and jCard terms. There is no such 
table on that page -- authors need to make guesses.

Whatsmore, in the example given, "tel" takes a single string as a value, 
whereas surely it should be an array? People can have multiple phone 
numbers. Ditto the single string for "email" and the single object for 

If these issues could be addressed, I'd be happy to work on a jCard output 
module for Cognition.
