<h1 id="lets-build-a-world-cup-widget-in-javascript">Let’s Build A World Cup Widget in JavaScript</h1>
<p>First let’s use an HTTP JSON API. Example:</p>
<pre><code>GET /event/world.2014/teams
{
"event": {
"key": "world.2014", "title": "World Cup 2014"
},
"teams": [
{ "key": "gre", "title": "Greece", "code": "GRE" },
{ "key": "ned", "title": "Netherlands", "code": "NED" },
{ "key": "ger", "title": "Germany", "code": "GER" },
{ "key": "por", "title": "Portugal", "code": "POR" },
...
]
}
</code></pre>
<p>Let’s ask the intertubes (let’s google <a href="http://www.google.com/search?q=json+world+cup+brazil"><code>json world cup brazil</code></a>
or post a question on the open data
stackexchange <a href="http://opendata.stackexchange.com/questions/1791/any-open-data-sets-for-the-football-world-cup-in-brazil-2014">‘Any Open Data Sets for the (Football) World Cup (in Brazil 2014)?’</a>).</p>
<p>Nothing. Nada. Nichts. Niente. Zilch. Zero.</p>

<div class='slide '>
<!-- _S9SLIDE_ -->
<h1 id="whats-footballdb">What’s <code>football.db?</code></h1>
<ul>
<li>
<p>Public domain football data sets offering free open football data
for the World Cup in Brazil 2014 and more.</p>
</li>
<li>
<p>Free self-hosted HTTP JSON API service for football data, for example:</p>
<ul>
<li>Step 1: Download the <code>worldcup2014.db</code> SQLite Database</li>
<li>Step 2: Serve up teams, rounds, matches, etc. via HTTP JSON API using the
<code>sportdb</code> command line tool</li>
</ul>
</li>
</ul>
<pre><code>$ sportdb serve
</code></pre>
<p>Services available include:</p>
<ul>
<li><code>/event/world.2014/teams</code> – List all teams</li>
<li><code>/event/world.2014/rounds</code> – List all rounds (matchdays)</li>
<li><code>/event/world.2014/round/20</code> – List all matches in a round e.g. - 20th Round (=> Final) </li>
</ul>
<pre><code>GET /event/world.2014/round/1

<p>“New” Structured Data Formats:</p>
<ul>
<li>DSLs (Domain-Specific Languages),

<p>Example - Open Football Match Schedule Language:</p>

<p>Q: Why? Why invent yet another data format? Why?</p>
<p>A: Best of both worlds, that is, 1) looks n feels like free-form plain text - easy-to-read and
easy-to-write - 2) but offers a 100-% data accuracy guarantee (when loading
into SQL tables, for example).</p>
