Hints for xfdashboard in universe

Hints

• asv-unknown-tag
  org.xfce.xfdashboard.metainfo.xml:179 - updatecontact
  Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
• asv-nonstandard-gnome-extension
  org.xfce.xfdashboard.metainfo.xml:187 - kudos
  This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
• asv-content-rating-missing
  org.xfce.xfdashboard.metainfo.xml -
  This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
• asv-developer-info-missing
  org.xfce.xfdashboard.metainfo.xml -
  This component contains no `developer` element with information about its author.
