Re: [Tracker] Does tracker support uniquie object-id across databases

[Remo Remo <remo rremo yahoo com>]

ok.. uris seems good solution..
btw, i found genre has no unique identifier (or uri).. so would tracker have the flexibity to create  new or update table for genre  which will store its own unique identifier?

That's not completely correct. Each artist, album, playlist has its own URI (based on uuid in some cases). "Song" is nmm:MusicPiece and share uri with the DataObject (the media file in your terminology)

but i found tracker is generating

As you say, it is an *internal* ID. You can access it with the tracker:id function, but it is not recommended at all. URIs are the identifiers of the resources.

Indeed, the uris has quite more chances to be unique between dbs...
