[[!template text="""So my thesis for this talk, why I'm giving this talk,""" start="00:00:24.640" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""is that I'm interested in SQLite.""" start="00:00:27.133" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""in a way that is, I think,""" start="00:00:49.154" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""a little bit unusual and perhaps compelling, I hope.""" start="00:00:52.583" video="mainVideo-sqlite" id="subtitle"]]
[[!template new="1" text="""So first of all, why SQLite?""" start="00:00:56.220" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""Why is this good? Well, SQLite is now built into Emacs.""" start="00:00:59.227" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""So you get a few things out of this when you use it for data.""" start="00:01:06.080" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""First of all, it's a database.""" start="00:01:12.217" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""It's extremely good for data, of course.""" start="00:01:14.580" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""There's a simplicity to data manipulation""" start="00:01:16.370" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""Text files are really not built for data.""" start="00:01:25.197" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""I think the overuse of text""" start="00:02:06.753" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""is part of this. Of course, text and using text,""" start="00:02:11.906" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""using files has awesome advantages as well.""" start="00:02:14.614" video="mainVideo-sqlite" id="subtitle"]]

[[!template new="1" text="""So let's talk about the triples package.""" start="00:02:29.870" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""The triples package is a package""" start="00:02:32.860" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""You don't have to do,""" start="00:02:40.420" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""you don't have to write SQL yourself.""" start="00:02:43.292" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""A lot of stuff is built in""" start="00:02:45.517" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""and is based on a very generic schema.""" start="00:02:47.925" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""That is, it's a single table.""" start="00:02:51.036" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""That table has, of course, fixed schema.""" start="00:02:53.840" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""It basically has three columns.""" start="00:02:55.230" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""the fourth column and why, but it's useful.""" start="00:03:01.194" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""So the three columns are subject, predicate,""" start="00:03:04.124" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""That sounds overly theoretical,""" start="00:03:23.956" video="mainVideo-sqlite" id="subtitle"]]

[[!template text="""You probably describe everything with it.""" start="00:03:32.006" video="mainVideo-sqlite" id="subtitle"]]
[[!template text="""It's very simple because the schema is fixed.""" start="00:03:33.330" video="mainVideo-sqlite" id="subtitle"]]
