What is Twitter's NameSpace xmlns?



What is Twitter’s NameSpace xmlns?

You have made Twitter cards with this code:

< meta name=“twitter:creator” content=“xxx” />

So you are using “twitter” so logically the xmlns should be this:


The trouble is you guys have not said what the xmlns is so how are machines meant to read your Twitter cards correctly?

Take facebook for example:

xmlns:article = “http://ogp.me/ns/article#

so then < meta property=“article:section” content="xxx "/>

Will work because there is a namespace. But with Twitter there is no such thing?

So does any developer at Twitter know the Twitter xmlns link please?
