Best metatag for copyright in html5

Question

What is the best metatag to use in a html5 page to add the name of the Agency/CMS that developed the web application?

I have found these 3 options:

<meta name="author" content="My CMS name dot com" />

<meta name="application-name" content="My CMS name dot com" />

<meta name="dcterms.rights" content="My CMS name dot com" />

Not sure that the first 2 are still valid in html5

Answer 1

In HTML5, you may only use names that are defined in the HTML5 spec or registered on WHATWG’s MetaExtensions wiki page. So these are the two places where you can look for appropriate names.

author is for the "name of one of the page's authors". As a (CMS) developer, you are probably not the author of the page, right?

application-name should not be used for the name of the CMS used to create the app, but for the name of the (created) app (only to be used if it’s an app, not for any kind of website).

dcterms.rights doesn’t seem to be appropriate; it’s for (information about) the rights, and not who has the rights. And besides that, it’s for the created site/app/content, not the tools that made it possible.

You could

• use generator for specifying the CMS that was used for creating the site

• use web_author/designer for specifying the name of the developer/designer

Answer 2

@ipel,

I agree with @unor's answer of not using the 3 potential meta tags you've highlighted.

Have you considered adding a humans.txt file instead? Last option would be to add an HTML comment at the start of the HTML document.
