Modifying the Wiki/collab service

Question

Hello,
I'm using the wiki service provided by the Server.app. The wiki works fine, but for a project a need to be able to display extra attributes in the documents overview. It would be ideal if I could also search for these attributes.
The main attribute I need is document expiration date.
I'm looking for a way to add attributes to documents and present them in several views.
Thanks,
René

The service file(used flex to generate template from PHP mySQL database then modified a bit):
public function getTempByOwner($itemOname) {
  $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename where o_name=?");
  $this->throwExceptionOnError();
  mysqli_stmt_bind_param($stmt, 's', $itemOname); 
  $this->throwExceptionOnError();
  mysqli_stmt_execute($stmt);
  $this->throwExceptionOnError();
  $rows = array();
  mysqli_stmt_bind_result($stmt, $row->Change_id, $row->Part_Changed, $row->Owner_id, $row->Datechanged, $row->Requester_id, $row->C_made, $row->device_id, $row->Network, $row->Status, $row->o_id, $row->o_name, $row->o_contactNo, $row->o_email, $row->department, $row->d_id, $row->s_n, $row->type, $row->location, $row->r_id, $row->r_name, $row->r_contactno, $row->company, $row->r_email);
     while(mysqli_stmt_fetch($stmt)) {
       $rows[] = $row;
       $row = new stdClass();
      mysqli_stmt_bind_result($stmt, $row->Change_id, $row->Part_Changed, $row->Owner_id, $row->Datechanged, $row->Requester_id, $row->C_made, $row->device_id, $row->Network, $row->Status, $row->o_id, $row->o_name, $row->o_contactNo, $row->o_email, $row->department, $row->d_id, $row->s_n, $row->type, $row->location, $row->r_id, $row->r_name, $row->r_contactno, $row->company, $row->r_email);
  if(mysqli_stmt_fetch($stmt)) {
       $row->Datechanged = new Datetime($row->Datechanged);
       return $row;
  } else {
       return null;
