Hey, what do you know? The database used by Syndication.framework on OS X is accessible with SQLite 3, assumedly by virtue of Core Data. Check out this barely presentable capture of what I just did in a shell window:

[11:34:49] deusx@Caffeina2:~/Library/Syndication$ sqlite3 Database3 
SQLite version 3.0.8
Enter ".help" for instructions
sqlite> .tables

Articles  Sources 

sqlite> .schema Articles

source_id INTEGER,author TEXT,title TEXT,contentType INT(1),
contents TEXT,excerpt TEXT,GUID TEXT,permalink TEXT,iconURL TEXT,

CREATE INDEX ArticleCurrents ON Articles (noComments);
CREATE INDEX ArticleDates ON Articles (date);
CREATE INDEX ArticleDatesRcvd ON Articles (dateReceived);
CREATE INDEX ArticleSources ON Articles (source_id);
CREATE INDEX ArticleUnreads ON Articles (unread);

sqlite> .schema Sources

There's one piece up there that had me do a coffee spit-take, though:

x_monkey TEXT,x_ninja TEXT,x_pirate TEXT,x_robot TEXT

Seems like the Syndication Wars have progressed, and the various sides have enlisted all of these combatting factions. Monkey vs Robot, Pirates vs Ninja--I only wonder whether the Ninjas and Robots will ally against the Monkeys and Pirates? It just seems natural.

  • Syndication framework doesn't actually use Core Data. The two were developed concurrently during Tiger, so Syndication wasn't built on top of Core Data.
  • Wow, this is pretty interesting from a programmer's perspective.
  • The column names were inspired by the freebie game Monkey, Ninja, Pirate, Robot published by Atomic Sock Monkey. It's fun! Try it!

    The fact that there are weird column names was inspired by sqlite's (then-)inability to add columns to existing tables. So the last time I had to break the schema to add a new column, I added four more as a reserve.

    Needless to say, the contents, schema and very existence of that database are subject to change without notice, etc. etc.
