>                 Key: TIKA-95
>                 URL: https://issues.apache.org/jira/browse/TIKA-95
>             Project: Tika
>          Issue Type: New Feature
>          Components: mime
>            Reporter: Jukka Zitting
>            Priority: Minor
>
> Some file formats like MS Office files or specific XML schemas don't have 
> simple magic marker bytes that could be used to easily identify the type of 
> the document. However, it would in many cases be possible to detect such 
> formats with more complex parsing logic.
> Also, there are some external libraries (like Sanselan as mentioned in 
> TIKA-92) that contain their own magic header rules. Instead of duplicating 
> such rules in Tika, it would be better if Tika could just invoke the existing 
> external functionality.
> To support these cases Tika should provide a mechanism to plug in custom 
> magic header detector components in addition to the traditional configured 
> magic patterns.
