      <sect2 id="webclient.intro.login">
        <title>Logging in</title>
        <para>
          There are three things that you need to know
          before you can use BASE:
        </para>
        
        <orderedlist>
        <listitem><simpara>The address (URL) to a BASE server</simpara></listitem>
        <listitem><simpara>A username to login with</simpara></listitem>
        <listitem><simpara>A password</simpara></listitem>
        </orderedlist>
        
        <para>
          You may, for example, try the BASE 2 demo server. Go to the
          URL <ulink url="http://base2.thep.lu.se:8080/demo/">http://base2.thep.lu.se:8080/demo/</ulink>
          and enter <userinput>base2</userinput> for the login and <userinput>base2</userinput>
          for the password.
        </para>
        
        <para>
          You need to get all three things from an administrator
          of the BASE server. If you know only the address to the
          BASE server, you may check the front page if the administrator
          has added any information about how to get a username/password
          there. Look for the <guilabel>Get an account!</guilabel> link on
          the front page.
        </para>
        
        <para>
          Logging in is simple, just enter your <guilabel>login</guilabel> 
          and <guilabel>password</guilabel> in the form on the front page
          and click the <guibutton>Login</guibutton> button. There is
          a checkbox which allows you to <guilabel>encrypt the password</guilabel>
          before it is sent to the BASE server. It is checked by default, and
          it is a good idea to leave it checked unless you have problems logging
          in. If you are sure you are entering the correct login and password,
          but still cannot log in, try unchecking the encryption option.
          If the checkbox is not visible, which happens if the server is
          using an external authentication server, the password is not encrypted.
        </para>
      </sect2>
      
      <sect2 id="webclient.intro.forgotten_password">
        <title>Forgotten password</title>
        <para>
          If you forget your password you will need to get a new one.
          BASE stores the passwords in an encrypted form that does not allow
          anyone, not even the server administrator, to find out the 
          un-encrypted password.
        </para>
        <para>
          To get a new password you will have to contact the server
          administrator. There may be a <guilabel>Forgot your password?</guilabel>
          link on the front page where the server administrator has entered
          information about how to get a new password.
        </para>

            Messages are sent by plug-ins to notify you about finished jobs. In the

            messages are not used for communication between users.

            <para>
            A list of projects that you are a member of. Projects are an important
            part of BASE and are the best way to share data when you are 
            cooperating with other users. We recommend
            that you always use a project when working with BASE. 
            For more information read <xref linkend="project_permission"/>.

            A list of important news and announcements from the

            information about server upgrades and maintenance.

      <sect2 id="webclient.intro.menubar">
        <title>Using the menu bar</title>
        <para>
          On the top of the home page is the <interface>Menu bar</interface>.
          This is the main navigation tool in BASE. It works the same way 
          as the regular menu system found in most other applications. Use
          the mouse to click and select an item from the menu. 
        </para>
        
        <para>
          Most of the menu is in two levels, ie. clicking on a top-level menu
          will open a submenu just below it. Clicking on something in the
          submenu will take you to another page or open a popup dialog window. 
          For example, the
          <menuchoice><guimenu>View</guimenu><guimenuitem>Samples</guimenuitem></menuchoice>
          menu will take you to the page listing samples and 
          <menuchoice><guimenu>File</guimenu><guimenuitem>Contact information</guimenuitem></menuchoice>
          opens a dialog where you can modify your contact information details.
        </para>
        
        <para>
          The menu bar also contains shortcuts to some often-used
          actions:

            <para>
            Refresh/reload the current page. This is useful when you add
            or modify items in BASE. Most of the time the page is refreshed
            automatically, but in some cases you will have to use
            this button to refresh the page.

            configurable and you can also make some item types 
            <emphasis>sticky</emphasis>. This will for example keep the shortcut
            to the last experiment even if you have viewed lots of other items
            more recently.

                This setting exists because different browsers render

                are too small you can change this setting to make them
                bigger.

        No matter what you are doing in BASE some things works more
        or less in the same way. This section covers things that are
        common for most parts of BASE.
      </para>
      
      <para>
        You mostly work with a single type of item at a time. This is
        reflected in the menu system. For example, use 
        <menuchoice>
          <guimenu>View</guimenu>
          <guimenuitem>Samples</guimenuitem>
        </menuchoice>
        to work with samples, and 
        <menuchoice>
          <guimenu>View</guimenu>
          <guimenuitem>Experiments</guimenuitem>
        </menuchoice>
        to work with experiments. In most cases the list view for that type
        of item is displayed. The list view, as the name says, 
        is used to list all items. There are two more standard views, the 
        single-item view and the edit view.

        <title>Create a new item</title>
        
        <para>
          New items are mostly created from the list view. For example,
          to create a new experiment go to the 
          <menuchoice><guimenu>View</guimenu> <guimenuitem>Experiments</guimenuitem></menuchoice>
          page. Here you will find a &gbNew; button in the
          toolbar. The button is disabled if you do not have permission to create new experiments. 
          Otherwise, click on it and enter any required information in the popup dialog.
          Sometimes there are multiple tabs in this dialog. In the case of experiments
          there are three tabs: <guilabel>Experiment</guilabel>, <guilabel>Publication</guilabel>
          and <guilabel>Experimental factors</guilabel>.
          
          As a general rule, only the first tab has information that is required. 
          The information in all other tabs are optional.
        </para>
        
        <para>
          In some places you will also find actions that create items
          directly in the list. For example in the list of samples or on
          the single-item view for a sample you can create an extract using that
          sample as the parent. If you use such links the parent
          item will in most cases be selected automatically, which saves
          you a few clicks when creating new items.
        </para>
        
        <para>
          Click on the &gbSave; button to save the new
          item to the database or on the &gbCancel; button
          to abort.
        </para>

        <note>
          <para>
          To speed up data entry when adding multiple new items there
          are a few tricks you can use to make the web client supply
          default values for most properties. To find a default value
          the following checklist is used in this order:
          </para>
        
        <orderedlist>         
          <listitem>
            <para>
            If the list have an active filter the filter values are
            used as default property values for the new item. For example,
            if you are listing experiments with <guilabel>Genepix</guilabel>
            raw data type the new experiment will automatically have
            <guilabel>Genepix</guilabel> selected. This trick should work
            for all properties except annotations, if it does not
            report it as a bug to the development team.
            </para>

          <listitem>
            <para>
            When you link to other items the same item will be used the next time.
            For example, if you create an extract and selects an extraction protocol
            the same protocol is used the next time you create another extract.
            In fact, BASE will remember as many items as specified by
            the 
            <guilabel>Recently used items</guilabel> setting (default is 4),
            allowing you to quickly select one of those protocols. 
            <xref linkend="webclient.configuration.preferences.appearance"/> 
            contains more information about the setting.

          On all single-item views there is an &gbEdit;
          button in the toolbar that opens a popup dialog for editing the properties

          You can also open the edit popup in most other places where
          the item appears, for example, in lists or the single-item view

          <keycap>ALT</keycap> or <keycap>SHIFT</keycap> keys while clicking
          on the link and the edit window will open in a popup. 
          If you do not have write permission
          on the item there is no meaning to open the edit popup and you will

        <para>
          Sometime it may be necessary to change the owner of an item.
          As an user you cannot give the ownership of your items to another
          user. It is instead the other user that must take the ownership
          of your items. For this to work, you must first give the other user
          permission to do so. That it, you must share your items with 
          <guilabel>Take ownership</guilabel> permission to other user. 
          See <xref linkend="webclient.items.share" />.
        </para>
        
        <para>
          When the items have been shared, the other user has to go to the
          list view (or the single-item view), mark the checkboxes for
          the items, and click in the <guibutton>Take ownership</guibutton>
          button. A warning message about not being able to undo the action
          is displayed. Click on &gbOk; to continue or
          &gbCancel; to abort.

          <para>
          The original owner may not have access permissions to the items
          any longer. If that is desired, the new owner must share the items
          to the original owner.

      <para>
        All pages that lists items are very similar in their appearance and
        functionality. In this section we will describe the things that are
        common for most (if not all) list pages.
      </para>
      
      <para>
        Use the menu to open a page listing items. Most list pages can only list one type of
        items. For example: use the
        <menuchoice>
          <guimenu>View</guimenu>
          <guimenuitem>Samples</guimenuitem>
        </menuchoice>
        menu to list samples and the
        <menuchoice>
          <guimenu>View</guimenu>
          <guimenuitem>Experiments</guimenuitem>
        </menuchoice>
        menu to list experiments.
      </para>

      <tip>
        An example of a list page that can list
        items of several types is found by going to 
        <menuchoice>
          <guimenu>View</guimenu>
          <guimenuitem>All items</guimenuitem>

        This page lists all items that you are the owner of. It has a few limitations:
        
        <itemizedlist>
          <listitem>
            <para>
              It support only a limited set of columns (type, name and description) 
              since these are the only properties that are common
              among all items.

          <listitem>
            <para>
              The list cannot be filtered (except by item type)
              or sorted. This is due to a limitation in the query system
              used to generate the list.

            should display. The navigation bar is repeated at the

        <para>
          Most lists are by default sorted by the name of the item. This can
          be changed by clicking on the column header of another column.
          If you click on the same column twice the sort order is reversed.
          A downwards or upwards pointing arrow is displayed next to the 
          column header in the column that is currently used for sorting.
          Column headers that are black cannot be used for sorting.
        </para>
        
        <para>
          It is possible to use more than one column for sorting. Press
          and hold one of the <keycap>CTRL</keycap>, 
          <keycap>ALT</keycap> or <keycap>SHIFT</keycap> keys while clicking 
          on another column header. The original sorting is kept and the new
          column is used for sub-sorting the list. The procedure can be 
          repeated with more columns if you need to sort on three or more
          columns. To revert to sort by only one column again click a 
          column header without holding down any key.

      <sect2 id="webclient.itemlist.filter">
        <title>Filtering the list</title>
        
        <para>
          If the list contains many items you may need to use a filter to be
          able to find the item you are looking for. The input boxes on the
          line below the column headers are used for filtering. Most columns
          are filtered using a free-text input box, but some columns that can
          only take a few distinct values use a selection list or radio buttons
          instead. The selection list and radio buttons are very simple to use.
          Just select the alternative that you want to filter on. The list
          will be automatically updated when the selection has been made.
        </para>
        
        <para>
          The free-text filter is a bit more complex. By default, an exact match is
          required, use % as a wildcard that matches any character. 
          For example, the filter <informalexample>Experiment A</informalexample> 
          only matches the same exact string, but the filter 
          <informalexample>Exp%</informalexample> matches 
          <informalexample>Experiment A, Experiment B, etc.</informalexample>
        </para>
        
        <para>
          You can also use operators to find items which has a value that
          is greater than, less than or not equal to a specific value. This is
          mostly useful on numeric or date columns but also works on text
          columns. The operator must be entered first in the
          free-text box, for example
          <informalexample>&lt;=10</informalexample>
          to find items which has a value less than or equal to 10.   
          Here is a list of the supported operators:
