I'm looking to add alternate language link statements in the head section of the page and update the sitemap with the corresponding alternate language links.

e.g. <link rel="alternate" hreflang="en" href="" />

Given a page load, in Velocity what would I use to check if there is a corresponding page for the same page identifier (assuming that's correct)?

I was going to use the following as it's performant: $dotcontent.find( identifier...)

However, I'm not sure if I can check the alternate language.

What would be the right way to detect this?

For the Sitemap I can probably handle that already.

Thank you,

For reference, we solved this by creating a VTL helper (Java plugin) to make use of the "ContentletAPI" and "findContentletForLanguage()" method.

We run some checks against the current page request and which language was requested vs which language the current page is, and then we use the above "findContentletForLanguage()" method to see if there is a corresponding version of the page for the alternate language.

If there is a match, we then output the necessary link statement in the head section of the page.

We already had a VTL helper (Java plugin), which meant it was easy enough to extend it's list of functionality.
