In order to unify metadata grabbing for all MythTV screens and plugins, the following universal metadata grabber format specification will be used. Metadata grabbing will be handled by common code with relatively little custom code necessary for new plugins. Grabber scripts must conform the the standard, and can otherwise "drop in" to provide metadata lookup for user plugins and core MythTV screens.

You can manually add metadata to your home videos by putting a single query result in a file named <basename>.mxml.

Explanation of supported tags

The "Used in" values below only reflect the tags which could be displayed in the plugins today. When writing your grabber script, you should feel free to use any and all tags listed to make data available to future improvements in MythTV.

Version Output

Important.png Note: For consistency between grabbers, please use the following format for your grabber version command line:

./grabbername -v

The version output enumerates the capabilities and information about your grabber to MythTV.

Query Results

Important.png Note: For consistency between grabbers, please use the following format for your grabber query command line:

./grabbername -M "query phrase"

A query result is nothing more than a series of items filled as completely as you care or are able to fill them. The only caveat is that a query (and by definition, any returned single item) must return an inetref to use in a followup query.
