Jolted by the work I've just been doing with RSS and Dashboard, I've been looking at the RSS provided by Advogato for my diary. The idea is I will link all the RSS files I generate from the <head> section of my blog using the <link rel="alternate" title="RSS" ... > mechanism, so that when browsing it with Dashboard enabled, I get not only my personal blog, but also my Advogato entries and O'Reilly weblog showing up too.
So, the Advogato RSS: it's a nice start, but there are one or two quirks.
The first is that the <title> element is missing. This is a mandatory element. Obviously Advo has no concept of title in diary elements so something like "Diary entry from edd on Mon, 16 Jun 2003" would do. But something is needed. Secondly, all the values of the <link> element are all the same, I suspect this is just a simple programming error.
(Being a purist, I have longer-term misgivings about cramming escaped HTML into the <description> field, but I am largely at war with common [ab]usage on that one.)
