a valid tag for “cheese”? Ditto “.asp” or “.php” variants? If not, why not?
Any file-name extension in the last path segment is part of the tag value: • http://example.com/cheese.htm ⇒ cheese.htm • http://example.com/cheese.asp ⇒ cheese.asp • http://example.com/cheese.php ⇒ cheese.phpThe rel-tag specification is clear on how to extract a tag from a URL. Special treatment for file-name extensions is not part of the extraction. Brian Suda gave an explanation on the microformats-discuss list (http://microformats.org/discuss/mail/microformats-discuss/2007-February/008538.html). Consider the following URLs, the tags that the following URLs give under the current specification, and the effect of requiring special treatment for file-name extensions on the tags that the following URLs give. • http://en.wikipedia.org/wiki/.htaccess • http://en.wikipedia.org/wiki/.Net • http://en.wikipedia.org/wiki/India.Arie • http://en.wikipedia.org/wiki/ASN.1 • http://en.wikipedia.org/wiki/L.I.E.
