</table>
If one of the requested events does not exist, it simply does not generate an <tt>Event</tt> block. It is permissible for the server to send an empty <tt>EventData</tt> tag if no data is available for the request.<p>
+
+<h3>Changing/Creating an Event</h3>
+
+The <tt>seteventdata</tt> transaction creates/changes an event. The request data looks like:<p>
+
+<pre>
+<Event id="0" ....>
+ <Title>....
+</Event>
+</pre>
+
+Attributes and tags are the same as for the <tt>geteventdata</tt> response. Except that the <tt>id</tt> attribute may contain the value <tt>"new"</tt> to create a new event, a negative integer is not allowed.<p>
+
+The response contains the ID of the new/changed event if the status is "Ok". In the case of failure the status will be "Error" and an optional reason for the failure may be in the body.
+
+<h2>Room related Transactions</h2>
+
+<h3>Getting Rooms</h3>
+
+The <tt>getroomdata</tt> transaction returns data about rooms in the database. The request data looks like this:<p>
+
+<pre>
+<GetRooms detail="basic">
+ <Room>ID of room</Room>
+ ...
+</GetRooms>
+</pre>
+
+The <tt>detail</tt> attribute may be "basic" or "full". If no <tT><Room></tt> tags are present all rooms are returned.<p>
+
+The response data looks like:<p>
+
+<pre>
+<RoomData>
+ <Room capacity="24">
+ <ID>Room ID</ID>
+ <Description>some encoded HTML text that describes the room</Description>
+ </Room>
+ ...
+</RoomData>
+</pre>
+
+The <tt>capacity</tt> attribute tells how many persons fit into the room. The <tt>ID</tt> tag contains the ID or Name of the room, the optional <tt>Description</tt> tag contains a description of the room - it is only present if full detail has been requested.
+
+<h3>Setting Rooms</h3>
+
+The <tt>setroomdata</tt> transaction is used to create/change one or more rooms, the request data looks like:<p>
+
+<pre>
+<RoomData>
+ <Room capacity="24">
+ <ID>Room ID</ID>
+ <Description>some encoded HTML text that describes the room</Description>
+ </Room>
+ ...
+</RoomData>
+</pre>
+
+The response simply contains the status "Ok" or "Error".
