##Question:

How should I approach `<link>`-ing a web document to **three or more** separate social media accounts, residing on one or more social media platforms (Facebook, LinkedIn, Twitter etc.)?

_____

## Exposition:

In the `<head>` of each article page on a given website, I would like to indicate a relationship  between that article page and **multiple** social media accounts.

At the very least, wherever possible, I would like to `<link>` each article-based web page to social media accounts for:

 - the website (ie. this website, which is hosting all the articles)
 - the article publisher's brand (ie. the publication the guest author is from)
 - the article author (ie. the guest author)

It's worth noting that:

 - the website is always the same
 - the publisher-contributor sometimes changes
 - the author-contributor often changes

**E.g.** I understand that a conventional link to a Twitter account looks like this:

    <link rel="me" href="https://twitter.com/example-twitter-account">

which is great, but given that (I've just learned) `rel="me"` is the [XFN](http://gmpg.org/xfn/) equivalent of `rel="author"`, I conclude this is an appropriate form to use only when referring to the author-contributor.

So what should I use for the publisher-contributor and for the website itself?

##Ideas:

For the website's own Twitter account, could I (possibly?) use `rel="alternate"` or should I be using `rel="[something else]"`?

I initially believed that I wouldn't be able to use `rel="author"` or `rel="publisher"` to link to social media accounts, because I was already using those `rel` attributes to express relationships with specific web pages.

But now it occurs to me that I might use `rel="publisher"` more than once, like this:

    <link rel="publisher" href="https://publisher-site.com/" />
    <link rel="publisher" href="https://twitter.com/example-publisher-account" />

**Added:**

I note that I can use the following:

 - This Website: `<meta name="twitter:site" content="@websiteAccount">`
 - Guest Author: `<meta name="twitter:creator" content="@authorAccount">`

But that's still only two out of three. It's missing the Guest Author's own Publication.

Additionally, it's Twitter-specific and I am looking for something like:

    <link rel="[relationship]" href="[social-media-url]" />

which I can apply to *any* social media platform (Facebook, LinkedIn etc.)
