MimeDir and VCard Java Interfaces

[Chris Hubick <chrish@xxxxxxxxxxxxx>]

Hi.

I am writing to ask for feedback on the attached Java interfaces which I
have created for exposing MimeDir and vCard data.

As part of my work for my employer, Athabasca University, I have created
a Java interface for exposing IEEE LTSC Learning Object Metadata (LOM). 
The LOM standard makes use of vCards for storing information about
metadata contributors.  I have thus desired a pure Java interface for
exposing associated vCard data through my LOM API, which is independent
of any particular vCard or MimeDir parser implementation.

Feedback appreciated, thanks.
