asv-content-rating-missing
com.google.sites.ser-player.appdata.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-cid-contains-hyphen
com.google.sites.ser-player.appdata.xml:4 - com.google.sites.ser-player.desktop
The component ID contains a hyphen/minus. Using a hyphen is strongly discouraged, to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`).
asv-desktop-app-launchable-omitted
com.google.sites.ser-player.appdata.xml -
This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
