Open Issues
-----------
* would it make sense to have 2-phase tag-reading
* 1st phase: get tag-data that are directly embedded in the data
* 2nd phase: get tag-data that has to be generated fetched
* e.g. album-art via web, video-thumbnails
* what about caching backends
* it would be good to allow applications to supply tagbin with a tagcache-
object instance. whenever tagbin gets a uri to tagread, it consults the
cache first. whenever there is a cache-miss it will tag-read and then store
in the cache
GstTagList *gst_tag_cache_load_tag_data (GstTagCache *self, const gchar *uri);
gst_tag_cache_store_tag_data (GstTagCache *self, const gchar *uri, GstTagList *tags);
