    <p>I am developing an open "protocol" for dynamic ridesharing services using mobile phones. It is based on XML-RPC and uses marshalled objects as parameters (quite like Soap).</p> <p>Every entity and operation will be heavily documented in the draft. As example, look at this first skeleton of a documented Prefs object to be used in the Protocol.</p> <hr> <p><strong>Prefs object</strong></p> <p>Stores the preferences of a Trip set by the Person who creates it [..]</p> <pre><code>Attribute Type Requirement age string MAY nonsmoking boolean MAY gender string MAY drive boolean MAY ride boolean MAY </code></pre> <ul> <li>Even if all attributes of Prefs objects are optional, objects of type Prefs MUST be provided when doing XML-RPC calls. In case of <strong>zero attributes</strong> provided, an empty object representend with an empty XML-RPC struct MUST be provided</li> <li><strong>gender</strong> <em>MUST</em> be any of the values <em>{'M', 'F', 'B'}</em>, meaning 'male', 'female' or 'both'</li> </ul> <p>The following is a valid Prefs object used in Protocol operations:</p> <pre><code>&lt;struct&gt; &lt;member&gt; &lt;name&gt;nonsmoking&lt;/name&gt; &lt;value&gt; &lt;boolean&gt;0&lt;/boolean&gt; &lt;/value&gt; &lt;/member&gt; &lt;member&gt; &lt;name&gt;gender&lt;/name&gt; &lt;value&gt; &lt;string/&gt; &lt;/value&gt; &lt;/member&gt; &lt;member&gt; &lt;name&gt;ride&lt;/name&gt; &lt;value&gt; &lt;boolean&gt;0&lt;/boolean&gt; &lt;/value&gt; &lt;/member&gt; &lt;member&gt; &lt;name&gt;drive&lt;/name&gt; &lt;value&gt; &lt;boolean&gt;0&lt;/boolean&gt; &lt;/value&gt; &lt;/member&gt; &lt;member&gt; &lt;name&gt;age&lt;/name&gt; &lt;value&gt; &lt;string&gt;18-40&lt;/string&gt; &lt;/value&gt; &lt;/member&gt; &lt;/struct&gt; </code></pre> <hr> <p>An operation using Prefs objects would have a complete description of an HTTP POST operation with all the details etc.</p> <p>Would you call this one a Protocol or still an API? I.e., if we write a Protocol which is based on another Protocol (in this case XML-RPC), is the derivative work a Protocol again?</p> <p>I would like to know that because I will talk about this in my bachelor thesis and I don't want to say something very stupid :)</p> <p>Thank you!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
