I'm very chary about your proposal. It mostly boils down to the following -

1. More Extractors - The extractors we currently have are decent. We could 
possibly target some more exif properties, but I'm not sure what else we 
should be targeting.

2. File writeback support - While this is a great thing to have I do not think 
it accounts for more than a week's work. Also I do not rate this very high on 
my priority list.

3. WebExtractor Support - I would absolutely love to have this in KDE, but I'm 
not too sure about Baloo. We're no longer a central storage mechanism. We're 
mostly about searching.

This would make a lot of sense with the respective applications - Juk and PMC, 
probably. Amarok - I'm not sure. Anyway, This will need to be discussed with 
those projects. I cannot mentor a project where I do not actively contribute.

Yup. You could re-use a lot of the web-extractor code. You could even make a 
library, but that *will* need to be discussed with the relevant applications

I've only seen one proposal by you. Are you no longer interested in KDevelop?
