== Q&A ==

# ''Should I use the more semantic <address> element for my hCards?''
#* Yes the <address> element is more semantic, but it is ''too'' specifically semantic for most hCard uses.  The poorly named <address> element really means <contact-info-for-this-web-page>.  The [http://www.w3.org/TR/html401/struct/global.html#h-7.5.6 HTML4 definition of the ADDRESS element] says it is used "to supply contact information for a document or a major part of a document such as a form."  Therefore <address> should be used for an hCard ONLY IF that hCard represents the contact information for the page or major part thereof.  One example of such a usage is on [http://tantek.com/log/ Tantek's blog].  Another way of saying this is the following two statements: Every <address> on a page SHOULD be an hCard. But not every hCard should be an <address>.
# ''Why is it necessary to put class name "url" on URL elements in the hCard when those hyperlinks already start with "http://", and that is enough to distinguish them from email links?''
#* The classname "url" is necessary to explicitly distinguish hyperlinks that are URL elements for the hCard, from email hyperlinks, as well as hyperlinks to photos, or other random hyperlinks that happen to be inside the hCard.
# I already have a vCard that i keep up-to-date. I don't want to change any references to it because it might break something else, what can i do?
#* You can use .HTACCESS to rewrite links to your vCard to a webservice that converts a page to the vCard dynamically, to do this you need to add something similar to your .htaccess file
<pre>
RewriteRule ^path/to/old.vcf http://suda.co.uk/projects/X2V/get-vcard.php\?uri=http://example.com/hCard_encoded.htm&filename=old.vcf
</pre>
Now you shouldn't have to do anything else, all links to the "old.vcf" are redirected to the webservice and will return a new vCard that is dynamially generated from your page.
