Does anyone know how to add OpenGraph meta tags using the HTML DSL? I need to be able to add tags such as

<meta prefix="og <http://ogp.me/ns#>" property="og:title" content="title" />

But the

META

class doesn't seem to support the

prefix

and

property

attributes. Currently I'm using

unsafe

to render the raw HTML, but I'd prefer not to.

There is a map-like property called

attributes

.

Good suggestion, it looks like this works:

meta {
    attributes["prefix"] = "og <http://ogp.me/ns#>"
    attributes["property"] = "og:title"
    content = "title"
}
