RFC 6350, "vCard Format Specification", August 2011

Source of RFC: vcarddav (app)
See Also: RFC 6350 w/ inline errata

Errata ID: 3845
Status: Verified
Type: Technical
Publication Format(s) : TEXT
Reported By: David Riggle

Section 6.2.4 says: 

       PHOTO:data:image/jpeg;base64,MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhv

It should say:

       PHOTO:data:image/jpeg;base64\,MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhv

Notes:

Section 3.4 states that all property values must have COMMA characters escaped with a BACKSLASH character. The PHOTO property value in the example contains a comma. Therefore it must be escaped with a backslash. Note that there are several other uses of the "data:" URI scheme in the document that also need to be corrected.

Alternatively, a different format for base64 encoded data could be used in vCard 4.0. The ENCODING=b format used in vCard 3.0 wasn't so bad.


----- Verifier notes -----
This represents a difference from earlier versions of vCard, and the ABNF does not support escaping for URIs. This errata report is correct and verified, but a full correction to the issue will have to wait for a document update.
