[Tracker] adding custom metadata for video

[Remo Remo <remo rremo yahoo com>]

Hi,

i am not well versed in nepomuk ontologies. All i get to know that they've defined some standard terms to represent your data. Here, there are some custom metadata i need to manage for my video/podcast files,... for e.g. i need to add video content's version/series number as an additional metadata.
i had googled it for associated ontologies mapping.. but with no luck.
would  tracker support to add/retrieve user-defined metadata?

Regards,
Remo
