I have been using ROME lately and it has a really nice feature: Modules. With the necessary modules installed, ROME can extract iTunes podcast, MediaRSS, etc. information from feeds. So it is also very useful to build a video/audio search engine. I haven't looked into feedparser in detail but it doesn't seem to have that. So ROME has as big plus here for me. Anyway, if the decision is to write an abstraction layer, I think RSSChannel and RSSItem classes (with an extra metadata field) will provide a good starting point. > > Cheers, > Chris > > > > Possibly use a different library to parse RSS feed for improved performance > > and compatibility > > --------------------------------------------------------------------------------------------- > > > > Key: NUTCH-444 > > URL: https://issues.apache.org/jira/browse/NUTCH-444 > > Project: Nutch > > Issue Type: Improvement > > Components: fetcher > > Affects Versions: 0.9.0 > > Reporter: Renaud Richardet > > Assigned To: Chris A.
