The search feature is a very powerful functionality of RSSOwl (the main reason
why I was interested in it).
I would like to develop a small information retrieval program over the data
stored by the application for personal purposes.
More precisely, I would like to have access to the content of the feeds and/or
the web pages they refer in order to count frequent words and other stuff. Is
there an easy way to get that information? I mean, to query the database and
produce simple text or XML files to process them in a second step? I have no
idea on how to do that. Maybe you can give me some hints.
You should be able to get this information from the Lucene index, its the
search engine used. otherwise, the DB is db4o, you would need to write some
Java code to access its data.
Is there some documentation on the RSSOwl database model ("tables"*, fields,
a.s.o.)? Which project file could help me to understand how it is interfaced
with db4o (e.g. DBManager.java)?
No there is no real documentation but basically anything that extends IEntity
is part of persisted entities in the db4o database. DBManager is a good start
for how we configure db4o for use, otherwise e verything of the package
org.rssowl.core.persist/internal and below that.
