[uf-discuss] Best practice for the "value" subproperty

[Costello, Roger L.]

Thanks David.

I just found an example in Brian Suda's book which shows microformat
markup adding data to HTML text.  For example, consider this HTML text:

     My home is a big, brown house...

The creator of this HTML text would like to add geo data, but has no
interest in displaying lat/lon decimal values.  However, making geo
information available to aggregators is of great interest.

Without impacting the HTML presentation geo data can be added:

<abbr class="geo" title="37.408183, -122.13855"> My home</abbr> is a
big, brown house...

The value of title is a composite value - lat, lon 

Cool!  

/Roger

Unfortunately, I don't think this is valid.  The real required field
is n (name), but hCard uses something called "implied n optimization"
[1] to derive n from fn (formatted name) if only fn is given.  This
simplifies the common case of "given-name family-name".  However, this
only works if fn is fairly simple.  If you want to include prefixes,
middle initials, suffixes, etc. then you have to fully specify the n
construct yourself.
