        <description>&lt;p&gt;
Users could write ckan extensions that offer previews for a certain datatype.
&lt;/p&gt;
&lt;p&gt;
Advantages:
&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;We can say that you can add your own previews
&lt;/li&gt;&lt;li&gt;Every preview would have to define it's own dependencies
&lt;/li&gt;&lt;li&gt;External development (community creates new extensions?)
&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;
Questions to answer:
&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;Specification of the interface
&lt;/li&gt;&lt;li&gt;Precedence of previews for the same data types
&lt;/li&gt;&lt;li&gt;Plugins only define the datatype that they are responsible for or do we call a function that returns whether the extension is responsible.
&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;
As far as I can see, this should be fairly easy to implement by following these instructions: &lt;a class="ext-link" href="http://docs.ckan.org/en/latest/writing-extensions.html#writing-a-plugin-interface"&gt;&lt;span class="icon"&gt;​&lt;/span&gt;http://docs.ckan.org/en/latest/writing-extensions.html#writing-a-plugin-interface&lt;/a&gt;
&lt;/p&gt;
