commit 7b0391b0b66704b201be0b54c7a72327b9049db7
Author: Carlos Garnacho <carlosg gnome org>
Date: Thu Mar 10 13:15:32 2011 +0100
extractor: mass change extractors
The API has changed, now the following function must be exported:
gboolean tracker_extract_get_metadata (const gchar *uri,
const gchar *mimetype,
TrackerSparqlBuilder *preupdate,
TrackerSparqlBuilder *metadata);
This was done in one go as there's no painless way to do this...
