Looks like the meta tag you want is

meta name=”original-source” content=”[url]”

However it looks like that is only for an entire page.

Solution 2:

Use the canonical tag, which tells the web engine crawler that the text is duplicated from the original website.

Example:

Place this in the header of your HTML page (in the duplicated content page)

<link rel="canonical" href="http://www.original-website.com" />

Solution 3:

No, HTML has no such element or attribute.

If you quote the content (in a qorblockuote element), you could use the cite attribute. But you must not use these elements for anything other than quotes.

If the whole document is duplicated (or is a subset), you could use the canonical link type. But you must not use this if only part of the document is duplicated while the other parts are different.
