.Site.LastChange is the date of the last modification on the entire site, not necessarily on the node we're currently showing, such as a taxonomy list.

Import of internal opengraph template from Hugo's `tpl/template_embedded.go`
|
|
until site authors and social metadata can be standardized[0]. Meanwhile, I
|
|
wanted to work on better usage of Twitter and Facebook OpenGraph tags[1][2].
|
|
|
|
First, because the .Site.Authors wiring doesn't work yet, several date-related
|
|
tags never get used, and also to correct the logic on these tags:
|
|
- All nodes/pages should use this metadata (it currently depends on .Site.Authors and .Social.Facebook)
|
|
- Published time should be flexible and use EITHER publishdate or date from frontmatter
|
|
- Modified time should use .Lastmod, which can use enableGitInfo and falls back seamlessly to .Date
|
|
- Nodes should use type "website" and og:updated_time
|
|
- Pages should use type "article" and article:modified_time
|
|
|
|
Several Twitter-related fields are incorrectly used:
|
|
- Site-specific Twitter account
|
|
- User-specific Twitter account
