Support for article:modified_time

[gmile]

Is it possible to add support for article:modified_time? This would probably require jekyll itself to support housekeeping of post modification dates?

We could, like jekyll-sitemap, rely on jekyll-last-modified-at to provide the information.
How do other sites (Facebook, Twitter, etc) use this info?

@pathawks to be honest I don't know.

Since this meta tag in http://ogp.me, I think it must be used by Facebook somehow. Although I understand having it listed in ogp probably doesn't mean is within the scope of jekyll-seo-tag.

I asked on stackoverflow and ogp mailing list for evidence of real world usage by Facebook, but got no answer so far.

The reason I opened this issue is because I'm writing a program that scrapes blog posts over the internet. Quite a few of wordpress / joomla blogs have this meta tag, while all jekyll blogs do not.

One of the major benefits of Last-Modified-At (LMA) is the ability to sort content based on last modified, allowing your users to see your freshest content first (example of what I mean for Hugo). LMA also allows users to easily add meta data to show last modified date, helping readers know when a post was last touched. In addition, use of LMA can be used to produce machine-readable time elements embedded in the content to aid content accessibility.

BTW, jekyll-sitemap plugin honors last_modified_at front-matter variable for generating sitemap.xml. I guess this should be a standard enforced at jekyll core itself.
