<p>This plugin turns your WordPress website into an <a href="http://en.wikipedia.org/wiki/Open_data" rel="nofollow ugc">open data</a> library. By using the dataset post type you can manage descriptions and meta information about open datasets.<br />
It is also possible to add descriptions of projects and apps that are using the datasets.</p>
<h4>Available languages</h4>
<ul>
<li>English by oxyva.nl</li>
<li>Dutch by oxyva.nl</li>
</ul>
<h3>Templates</h3>
<p>In order to include datasets and projects in your theme you have three options.</p>
<h4>1: Enable content filter</h4>
<p>When enabling the content filter options in the WP OpenData settings the metadata is printed above the actual content of either a dataset or a project, and a list of (related) projects is printed at the bottom of a dataset.</p>
<h4>2: Create your own templates/create a child theme</h4>
<p>If you want to customize the template for datasets and project you need to modify your template for the custom post types <code>dataset</code> and <code>project</code>. To do so visit these pages to read more about templates for custom post types:</p>
<ul>
<li><a href="https://codex.wordpress.org/Post_Type_Templates" rel="nofollow ugc">Post Type Templates – WordPress Codex</a></li>
<li><a href="https://codex.wordpress.org/Template_Hierarchy" rel="nofollow ugc">Template Hierarchy – WordPress Codex</a></li>
<li><a href="https://codex.wordpress.org/Child_Themes" rel="nofollow ugc">Child Themes – WordPress Codex</a></li>
</ul>
<p>For example, to create a single dataset page you have to create a template file called <code>single-dataset.php</code>.</p>
<p>You can use the following functions in your template:</p>
<ul>
<li><code>wp_opendata_entry_meta_dataset()</code>: prints the post entry meta data for a dataset. For example: “This project was posted on April 26, 2013”.</li>
<li><code>wp_opendata_entry_meta_project()</code>: prints the post entry meta data for a project.</li>
<li><code>wp_opendata_dataset_meta()</code>: prints the meta data of a dataset in an HTML definition list. This list contains for example the licenses, URL, categories and tags. When the current post is not of type <code>dataset</code> nothing will be printed.</li>
<li><code>wp_opendata_project_meta()</code>: prints the meta data of a project in an HTML definition list. When the current post is not of type <code>project</code> nothing will be printed.</li>
<li><code>wp_opendata_meta()</code>: prints the metadata of either a project or a dataset.</li>
<li><code>wp_opendata_next_post($format = '%link &raquo;', $link = '%title', $post_type = '')</code>: prints the next (alphabetically ordered) dataset or project. Change the <code>$post_type</code> parameter to <code>dataset</code> or <code>project</code>.</li>
<li><code>wp_opendata_previous_post($format = '%link &raquo;', $link = '%title', $post_type = '')</code>: prints the previous (alphabetically ordered) dataset or project. Change the <code>$post_type</code> parameter to <code>dataset</code> or <code>project</code>.</li>
<li><code>wp_opendata_get_dataset_project_list</code>: get an array containing name and url elements of projects that are using the current dataset. Returns null when no projects are found.</li>
<li><code>wp_opendata_dataset_project_list()</code>: prints an HTML list element containing projects that are using the current dataset.</li>
</ul>
<p>In order to view an example open the <code>single-dataset.php</code> and <code>content-dataset.php</code> file in <code>wp-content/plugins/wp-opendata/templates/</code>.</p>
<h4>3: Edit existing templates of your theme</h4>
<p><em>Caution: it is advised to use this option only if you have developed the theme yourself. When updating a third-party theme changes made to the template files might be lost.</em></p>
<p>In order to print the meta information of a dataset or a project add the following line in the <code>single.php</code> template file:</p>
<pre><code><?php wp_opendata_meta(); ?>
</code></pre>
<p>The following code can be used to print a list of (related) projects for a dataset (<code>h2</code> header with an unsorted list):</p>
<pre><code><?php wp_opendata_dataset_project_list(); ?>
</code></pre>
<p>When the current post is not of type <code>dataset</code> or <code>project</code> nothing will be printed. Make sure the content filter options are turned off in the WP OpenData settings, else the metadata is shown twice.</p>
