Is there a standardized (meta?) tag for the date of a website?
One thing that search engines really suck with is the date when a website was created. You know the problem: You search for some CSS or JavaScript problem and Google returns a ton of results from 2002 explaining how to fix the problem in IE 5.5 and Netscape 4.6 while the helpful articles are buried on Page 3.
Anyway, I just wonder if there is a standardized or at least generally accepted tag or meta tag that I can put on my own pages to indicate the date they were created?
Not that it helps filtering out the old crap out of search results (especially since the people at #1 with their 2002 articles have zero incentive to change), but I'd just like to do my part :P
Answer
There have been a few WHATWG Meta Extension proposals, referenced in the HTML5 specification which could cater for the creation date of a page.
"Accepted" Proposals
dcterms.available - The date the resource became available.
dcterms.created - The creation date of the resource.
dcterms.dateAccepted - The date the resource was accepted.
dcterms.submitted - The date the resource was submitted.
dcterms.issued - The publication date of a resource.
Related "Accepted" Proposals
dcterms.modified - The modification date of a resource
dcterms.valid - The validity of the resource.
There are a couple of "incomplete proposals" which haven't been accepted due to a lack of documentation (such as created).
I don't believe Hangy's answer of dc.date (now dcterms.date) would be relevant here as, as far as I'm lead to believe, the date of this is the date associated with the resource. For example, if the resource was a discussion about the Battle of Hastings in 1066, the dcterms.date could be set to 1066. The same could also be said for icas.datetime.
