feed rss and isPermalink=false how to behave
<p>I'm starting making a rss feed reader application and I don't know how to structure it.
Basically, there will be an sqllite db in which I'll save up to x articles, removing older ones as feed number increases. In a list user can choose which article read and another activity opens up with full text.</p>

<p>Problem is that articles can be very long so I don't want to store the entire text in the db, but I'd like to store just the link, thus downloading it from the net when user wants to read it.</p>

<p>There's a catch: each article has isPermaLink=false attribute, so I guess this link will not last forever..how can I solve?I don't want to store words and words in the db: user would kill my app and me with it!</p>

<p>If I could know after how much time the article is removed from website I could at least do some cleanup operation(=deleting from db articles whose link are expired) when app starts, but I'm afraid I can't or, at least, I don't know if this information is in the rss file.</p>

<p>Help :)</p>
