+ − <p>
+ − Any of the <it>user</it> objects can be submitted to an LTPDA repository
+ − </p>
+ −
+ − <p>
+ − There are three different methods which submit/update object(s) to the repository:
+ − <ul>
+ − <li><h3>submit</h3>
+ − Submits the given collection of objects to an LTPDA Repository. If multiple objects
+ − are submitted together, a corresponding collection entry will be made. The objects
+ − are stored as a XML representation <b>and</b> if possible a binary representation
+ − (see bsubmit).</li>
+ − <li><h3>bsubmit</h3>
+ − Submits the given collection of objects to an LTPDA Repository. If multiple objects
+ − are submitted together, a corresponding collection entry will be made. The objects
+ − are stored <b>only</b> as a binary representation.<br />
+ − In order to retrieve this object by calling a constructor it is necessary to
+ − set the key <tt>'BINARY'</tt> to 'yes' because the XML representation doesn't exist.
+ − For example the AO constructor
+ − <a href="matlab:web(ao.getInfo('ao', 'from repository').tohtml, '-helpbrowser')">'From Repository'</a>
+ − </li>
+ − <li><h3>update</h3>
+ − Updates the specified object with a new object.
+ − </li>
+ − </ul>
+ − </p>
+ −
+ − <h2>The submission process</h2>
+ −
+ − <p>
+ − When an object is submitted, the following steps are taken:<br />
+ − <ol>
+ − <li>The <tt>userid</tt> of the user connecting is retrieved from the <it>Users</it> table of the repository</li>
+ − <li>For each object to be submitted:
+ − <ol>
+ − <li>The object to be submitted is checked to be one of the types listed above</li>
+ − <li>The <tt>name</tt>, <tt>created</tt>, and <tt>version</tt> fields are read from the object</li>
+ − <li>The object is converted to an XML text string</li>
+ − <li>An MD5 hash sum is computed for the XML string</li>
+ − <li>The XML string and the hash code are inserted in to the <tt>objs</tt> table</li>
+ − <li>The automatically assigned ID of the object is retrieved from the <tt>objs</tt> table</li>
+ − <li>An attempt is made to create a binary representation of the object (.MAT). If this is possible, the binary data is inserted in the <tt>bobjs</tt> table.</li>
+ − <li>Various pieces of meta-data (object name, object type, created time, client IP address, <i>etc.</i>) are submitted to the <tt>objmeta</tt> table</li>
+ − <li>Additional meta-data is entered into the table matching the object class (<tt>ao</tt>, <tt>tsdata</tt>, <i>etc.</i>)</li>
+ − <li>An 'in' entry is made in the <tt>transaction</tt> table recording the user ID and the object ID</li>
+ − </ol>
+ − </li>
+ − <li>A entry is then made in the <tt>collections</tt> table, even if this is a single object submission</li>
+ − <li>The object IDs and the collection ID are returned to the user</li>
+ − </ol>
+ − </p>
+ −
+ − <br />
+ − <h2>Submitting objects</h2>
+ −
+ − <p>
+ − Objects can be submitted using the command <tt>submit</tt>. This command takes at least two inputs:
+ − <table border="1" cellpadding="2" width="30%" bgcolor="#DDDDDD">
+ − <tr valign="top">
+ − <td><tt>object</tt></td><td>The object(s) to submit</td>
+ − </tr>
+ − <tr valign="top">
+ − <td><tt>pl</tt></td><td>A plist containing various pieces of information (see below)</td>
+ − </tr>
+ − </table>
+ − </p>
+ − <p>
+ − The <tt>plist</tt> details can be found at: <a href="matlab:web(ltpda_uo.getInfo('submit').tohtml, '-helpbrowser')">Parameter Sets</a>
+ − </p>
+ − <p>
+ − The following example script connects to a repository and submits an AO:
+ − <div class="fragment"><pre>
+ −
+ − <span class="comment">% Connect to a repository</span>
+ − conn = utils.jmysql.connect(<span class="string">'localhost'</span>, <span class="string">'ltpda_test'</span>);
+ −
+ − <span class="comment">% Load the AO</span>
+ − a = ao(<span class="string">'result.xml'</span>);
+ −
+ − <span class="comment">% Build an information plist</span>
+ − pl = plist;
+ − pl.append(<span class="string">'conn'</span>, conn);
+ − pl.append(<span class="string">'experiment title'</span>, <span class="string">'Interferometer noise'</span>);
+ − pl.append(<span class="string">'experiment description'</span>, <span class="string">'Spectral estimation of interferometer output signal'</span>);
+ − pl.append(<span class="string">'analysis description'</span>, <span class="string">'Spectrum of the recorded signal'</span>);
+ − pl.append(<span class="string">'quantity'</span>, <span class="string">'photodiode output'</span>);
+ − pl.append(<span class="string">'keywords'</span>, <span class="string">'interferometer, noise, spectrum'</span>);
+ − pl.append(<span class="string">'reference ids'</span>, <span class="string">''</span>);
+ − pl.append(<span class="string">'additional comments'</span>, <span class="string">'none'</span>);
+ − pl.append(<span class="string">'additional authors'</span>, <span class="string">'no one'</span>);
+ −
+ − <span class="comment">% Submit the AO</span>
+ − [ids, cid] = submit(a, pl);
+ −
+ − <span class="comment">% Close the connection</span>
+ − conn.closeConnection
+ − </pre></div>
+ − The ID assigned to the submitted object is contained in the first output of the <tt>submit</tt> function:
+ − <div class="fragment"><pre>
+ − <span class="comment">% Inspect the object ID</span>
+ − disp(ids)
+ − 212
+ − </pre></div>
+ − If the <tt>plist</tt> contains sufficient information, it is possible to overide the appearance of the
+ − 'submission' dialog by giving the key/value pair: 'no dialog', <tt>true</tt>.
+ − </p>
+ −
+ − <h2>Submitting collections</h2>
+ − <p>
+ − Collections of LTPDA objects can also be submitted. Here a collection is defined as a group of objects
+ − submitted at the same time. In this way, a single information structure describing the collection is
+ − assigned to all the objects. The collection is just a virtual object; it is defined by a list of object IDs in the database.
