media.xml

media.xml adds package-defined attributes to media items.

Use it when a package needs additional metadata on files or folders in the project media area. Keep attribute names package-scoped because media attributes are shared with the project media system.

Basic Structure

Create media.xml in the package root.

<?xml version="1.0" encoding="UTF-8"?>
<quiqqer>
    <media>
        <attributes>
            <attribute>vendor.package.media.flag</attribute>
            <attribute default="0">vendor.package.media.sortIndex</attribute>
        </attributes>
    </media>
</quiqqer>

QUIQQER scans installed packages for media.xml and reads attributes from:

quiqqer/media/attributes/attribute

Each attribute entry provides:

• the attribute name as the element text
• an optional default attribute

Attribute Names

Use stable, package-scoped names.

<attribute>vendor.package.media.previewMode</attribute>

Do not use generic names such as type, status, or enabled. They are hard to trace once multiple packages add media metadata.

Defaults

Use default when new media items should receive an initial value.

<attribute default="standard">vendor.package.media.displayMode</attribute>

Defaults should be simple scalar values because they are imported as attribute metadata.

Practical Checklist

Before adding media.xml:

• Add it only when package code reads or writes media item attributes.
• Use package-scoped attribute names.
• Keep defaults simple.
• Document the attribute meaning in the package README when administrators or integrators need to understand it.
