AppStream Report for Debian - Issues for jumpnbump in sid/main

Warnings

no-metainfo
This software component is missing a MetaInfo file to provide metadata.
We currently took some data from its desktop-entry file and the long description of the package it is located in.
This has several disadvantages, like poor markup, too technical descriptions for users of software centers, different components having the same description, etc.
Additionally, a lot of software with desktop-entry files should either not be installable and searchable via the software catalog (like desktop-specific settings applications) or be tagged accordingly via MetaInfo files.
Please consider to either hide this desktop-entry file from AppStream by adding a X-AppStream-Ignore=true field to it, or to write a MetaInfo file for this component and send it upstream.
Generating components from non-MetaInfo files is deprecated, if you do not add a MetaInfo file, this software may vanish from the metadata catalog (and if it is a GUI application, no longer be visible in software centers) in a future distribution release.
You can consult the MetaInfo quickstart guides for more information on how to write a MetaInfo file, or file a bug with the upstream author of this software component.

asv-cid-desktopapp-is-not-rdns
jumpnbump.appdata.xml:4 - jumpnbump.desktop
The component ID is not a reverse domain-name. Please update the ID to avoid future issues and be compatible with all AppStream implementations. You may also consider to update the name of the accompanying .desktop file to follow the latest version of the Desktop-Entry specification and use a rDNS name for it as well. In any case, do not forget to mention the new desktop-entry in a <launchable/> tag for this component to keep the application launchable from software centers and the .desktop file data associated with the metainfo data.
asv-screenshot-no-media
jumpnbump.appdata.xml:44 -
A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
asv-type-property-required
jumpnbump.appdata.xml:48 - translation ()
This tag requires a type property.
asv-tag-empty
jumpnbump.appdata.xml:48 - translation
The mentioned tag is empty, which is highly likely not intended as it should have content.

asv-desktop-app-launchable-omitted
jumpnbump.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.
asv-developer-info-missing
jumpnbump.appdata.xml -
This component contains no `developer` element with information about its author.
