Extended attributes data

User extended attributes are named pieces of information that most modern file systems can attach to any file.

Recoll versions 1.19 and later process extended attributes as document fields by default. For older versions, this has to be activated at build time.

A freedesktop standard defines a few special attributes, which are handled as such by Recoll:


If set, this overrides any other determination of the file MIME type.


If set, this defines the file character set (mostly useful for plain text files).

By default, other attributes are handled as Recoll fields. On Linux, the user prefix is removed from the name. This can be configured more precisely inside the fields configuration file.
