I have explored the code of the file indexers, and there is a file named
properties.h (it declares the valid properties that can be used when
extracting files). This list is quite extensive and seems to alleviate
my problem: I thought that only the 5-6 properties listed at the
beginning of the file search store source code (in Baloo Core) were
available.
By the way, PropertyInfo is also very interesting and it may be
interesting to use it in the query parser (so that the user can enter
"artist is Foo" and queries like that). This justifies putting the query
parser in a separate library to avoid a cyclic dependency between Baloo
Core and kfilemetadata.
* "Remote" file extractors: if the user asks for it, such extractors
could be used to query IMDB for tags and attributes. This should not be
automatic as downloading web pages takes time and bandwidth, but having
a button in FileMetadataWidget to perform this task may be useful to
many people. Nepomuk had a concept of "indexing level", does a similar
concept exist in Baloo?
Having online content is always useful, but in the right settings. It may not
be very useful in Dolphin which is after all a file manager, but it would be
very very useful in a media application.
In that case the media player would be responsible for deciding when to fetch
the online data. And then, we don't really need to store that information in
the same index as the current files. Unless this needs to be part of the global
search.
This is probably best discussed with the multimedia guys, Plasma Media Center,
and Jorg who did the Nepomuk web-extractor.
Okay, I will talk to them. Storing this kind of meta-data directly in
the Baloo database could be useful because it would allow a generic
application (like a Baloo browser or search engine, or a file manager)
to find documents and media content based on any search. For instance,
an application like Plasma Media Center (or even Plasma Active) could
display files sorted by album, author, composer, series, origin, type, etc.
