title: FIWARE, NGSI-LD - Understand the @context
body: <p>I am creating a data model for a particular application and I did not start from any base model; since I did not start from any base model, the context below is sufficient, correct?</p>
  <pre><code>&quot;@context&quot;: [
              &quot;https://schema.lab.fiware.org/ld/context&quot;,

  <p>My data model is not complicated, with just these properties and entity being more &quot;complex&quot;:</p>
  <pre><code>&quot;address&quot;: {
              &quot;type&quot;: &quot;Property&quot;,
              &quot;value&quot;: {
                  &quot;streetAddress&quot;: &quot;&quot;,
                  &quot;postalCode&quot;: &quot;&quot;,
                  &quot;addressLocality&quot;: &quot;&quot;,
                  &quot;addressCountry&quot;: &quot;&quot;
              }
  },
  </code></pre>
  <pre><code>&quot;location&quot;: {
              &quot;type&quot;: &quot;Point&quot;,
              &quot;coordinates&quot;: [
                  ,
              ]
  },
  </code></pre>
