Help:Media files and metadata



Adding metadata to media files will help to make them queryable and extend the content horizon in which those files are uploaded.

A user is always able to provide specific information about a file in form of annotations but certain data can be retrieved automatically and autonomously to build a better information platform about files and their content.

Type data
While not enabled by default, the following properties are suggested to be added to so that rudimentary information about a file can be stored and made available out-of-the box:

Attachment links
Recognizing (or track) where each file (or image) is attached to, can provide the means for it.

Exif data
provides additional capabilities to fetch and annotated Exif (Exchangeable image file format) information from a file.

Content information
The Elasticseach store provides a functionality to parse the entire content of a file outside of the wiki and is able to transfer back some metadata to the wiki. If enabled, it adds a file attachment container which holds data from the "Apache Tika" pluginCiteRef::web:tika.apache.org and provides information (if provided by the file) about:
 * Content author
 * Content date
 * Content language
 * Content length
 * Content title
 * Content type
 * Content keyword
