<title>Generating and Maintaining Logs with RDLogEdit</title>
<sect1 xml:id="sect.rdlogedit.logs_and_log_events">
<title>Logs and Log Events</title>
<para>
A Rivendell log is a sequence of one or more events to be executed by
the system, arranged in chronological order. (This functionality is
sometimes referred to as a playlist in other automation systems).
Several different types of events can be included in a log, along
with parameters governing how and under what circumstances they will
be executed.
</para>
<para>
Upon startup, RDLogEdit will show the current list of all logs on the
system. A number of important attributes of
logs can be seen from <xref endterm="para.rdlogedit.the_rdlogedit_main_window" endlink="mediaobject.rdlogedit.rdlogedit_screenshot"/>, the first being the log
name, with a summary status indicator next to it. The name is an
alpha-numeric label that is used as a unique “handle” by the system
to reference each log, and can be up to a maximum of 64 characters
long. The status indicator is intended as a quick visual guide as
to whether a particular log is ready for air (green check mark) or
not (red ex).
</para>
<para>

<para xml:id="para.rdlogedit.the_rdlogedit_main_window">The RDLogEdit Main Window</para>
</caption>
</mediaobject>
</para>
<para>
Next comes the log's unique <computeroutput>Name</computeroutput>,
assigned at the time the log was created, followed by it's
<computeroutput>Description</computeroutput>.
This is a free-form alpha-numeric
label that can be used to record any information that might be useful
to have appear on the log list (e.g. “This log for Sunday's show, don't
modify!”).
</para>
<para>
Next comes a column showing the owning
<computeroutput>Service</computeroutput>. Each log is owned
by exactly one service, which determines under what circumstances
the log can be played and where electronic log reconciliation (ELR)
data resulting from log playouts is sent (for an overview of
Rivendell services, see <xref linkend="sect.overview.services"/>).
</para>
<para>
Next comes three “status indicator” columns
(<computeroutput>Music</computeroutput>,
<computeroutput>Traffic</computeroutput> and
<computeroutput>Tracks</computeroutput>) indicating the log's
degree of readiness for air. A red indicator indicates that the
particular data element is required but currently missing, a green
indicator indicates an element is required and present, while a
white indicator indicates that an element is not required.
Additionally, the <computeroutput>TRACKS</computeroutput> column
contains a pair of numbers
indicating how many completed voice tracks exist in the log versus
how many total track markers exist (the subject of voice tracks and
track markers will be covered in more detail below). When all three
of these status indicators show either green or white, the summary
status indicator (at the beginning of the log's entry in the list)
will show as a green check mark, while a red indicator in any of
these three fields will show a red ex. (NOTE: because a log sports
a red ex does not indicate that the respective log cannot be played.
It is merely a visual indicator to allow logs to be quickly
&quot;eyeballed&quot; for completeness).
</para>
<para>
Next comes a pair of columns indicating the valid start date and end
date for the log.
</para>
<para>
Next comes an <computeroutput>Auto Refresh</computeroutput> column
that indicates whether the log has auto refresh enabled. (For a
discussion of auto refresh, see FIXME).
</para>
<para>
Finally, there are &quot;datestamp&quot; columns, indicating
date/time of the log's <computeroutput>Origin</computeroutput>,
<computeroutput>Last Linked</computeroutput> and
<computeroutput>Last Modified</computeroutput> operation.
</para>
<para>
A report that lists the available logs on the system can be generated
by touching the <computeroutput>Log Report</computeroutput> button.
</para>
<para>
A new log can be created by touching the
<computeroutput>Add</computeroutput> button and entering a
name, or an existing log inspected and modified by touching its entry
on the log list and then touching the
<computeroutput>Edit</computeroutput> button, resulting in the
log being opened in the Edit Log dialog.
The Edit Log dialog consists of three parts: the top section, where
much of the information shown on the log list can be inspected and
modified; the middle section, which shows the list of events
comprising the log, and the bottom section, where buttons for
modifying and saving the log are located. Each event in a log can
be one of several different types, indicated by the icon displayed
at the start of the line (see
<xref linkend="table.rdlogedit.log_event_type_icons"/> for a
breakdown of the various icons).

<sect2 xml:id="sect.rdlogedit.audio_carts">
<title>Audio Carts</title>
<para>
The first, and usually most common type of log event is an audio cart.
As the name implies, audio carts are Library entries that contain
audio material intended for playout. Audio carts were covered in
detail in <xref linkend="chapter.rdlibrary"/>.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.macro_carts">
<title>Macro Carts</title>
<para>
A macro cart is a cart from the Library that contains one or more
system commands that can be used to cause the system to take various
actions. They were touched upon in
<xref linkend="chapter.rdlibrary"/>, and will be discussed in detail
in <xref linkend="chapter.rml"/>.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.note_markers">
<title>Note Markers</title>
<para>
A note marker is an entry in the log that contains text intended to
be seen by operators and used as a guide or reminder (program coders
sometimes refer to this sort of functionality as a
<emphasis>remark</emphasis> or <emphasis>comment</emphasis>,
as seen in the <code>REM</code> command used by BASIC programmers).
Note markers
belong to a class of log events known as meta events because (unlike
carts, which exist in the Library independently of whether they are
placed in a log or not), they have no independent existence outside
of the specific log where they are placed. A note marker has
absolutely no effect on the execution of a log other than to simply
display some text at a specified point in a log, and as such can be
useful as a mechanism for making notes or reminders to oneself or
to others who may be executing the log.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.track_markers">
<title>Track Markers</title>
<para>
A track marker is another meta event that is very similar in operation
to note markers, with one key addition: track markers designate or
&quot;bookmark&quot; a place in the log where a voice track is to be
recorded. (The entire topic of voice tracks and tracking will be
covered in detail in <xref linkend="chapter.voicetracking"/>).
As with note markers, track
markers have absolutely no effect on the execution of a log.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.chain_events">
<title>Chain Events</title>
<para>
Each event in a log has a transition type, shown in the
<computeroutput>Trans</computeroutput>
column of the Edit Log dialog. The transition type determines what
happens when one event in a log ends and the next starts. Three basic
transition types can exist in a Rivendell log:
<computeroutput>PLAY</computeroutput>,
<computeroutput>SEGUE</computeroutput> and
<computeroutput>STOP</computeroutput>.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.import_links">
<title>Import Links</title>
<para>
An import link is a placeholder event that shows where events imported
from the external music or traffic scheduling system will eventually
go. They will be covered in detail in
<xref linkend="chapter.rdlogmanager"/>.
</para>
<para>
Each event in a Rivendell log can have its parameters modified by
touching its entry in the Edit Log dialog and then clicking the
<computeroutput>Edit</computeroutput>
button, thus opening up the Edit Log Entry dialog, shown below.

<title>Event Transitions</title>
<para>
Each event in a log has a transition type, shown in the
<computeroutput>Trans</computeroutput>
column of the Edit Log dialog. The transition type determines what
happens when one event in a log ends and the next starts. Three basic
transition types can exist in a Rivendell log:
<computeroutput>PLAY</computeroutput>,
<computeroutput>SEGUE</computeroutput> and
<computeroutput>STOP</computeroutput>.
</para>
<sect2 xml:id="sect.rdlogedit.the_play_transition">
<title>The PLAY Transition</title>
<para>
If an event has a <computeroutput>PLAY</computeroutput> transition,
then it will begin playing when
the previous event has finished.
<computeroutput>PLAY</computeroutput> transitions are used when
automatic event sequencing is desired with no audio overlap (such
as when playing two voice-only announcements back-to-back).
</para>
</sect2>
<sect2 xml:id="sect.the_segue_transition">
<title>The SEGUE Transition</title>
<para>
<computeroutput>SEGUE</computeroutput> transitions are similar to
<computeroutput>PLAY</computeroutput> transitions, with one key
difference: if the finishing event contains segue data (either from
the Library or from a custom transition programmed in the voice
tracker), then the event will start before the prior event is
finished, causing the two pieces of audio to overlap and mix together.
<computeroutput>SEGUE</computeroutput> transitions can be a very
powerful tool for creating a variety
of special effects, particularly when used in conjunction with
musical material.
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.the_stop_transition">
<title>The STOP Transition</title>
<para>
As the name implies, <computeroutput>STOP</computeroutput>
transitions cause execution of the log to
be suspended prior to execution of the event. This is often the
desired behavior in situations where the log playout needs to be
synchronized to one or more external audio sources (such as remote
satellite feeds), and is commonly used in conjunction with Hard
Timed events (see <xref linkend="sect.rdlogedit.time_and_time_types"/>).
</para>
</sect2>
</sect1>
<sect1 xml:id="sect.rdlogedit.time_and_time_types">
<title>Time and Time Types</title>
<para>
All Rivendell log events have an associated time type, which controls
what effect (if any) the passage of time will have on the event.
There are two basic time types: <emphasis>relative</emphasis> and
<emphasis>hard</emphasis>. Additionally,
the hard time type has several additional options that further modify
its behavior.
</para>
<sect2 xml:id="sect.rdlogedit.the_relative_time_type">
<title>The Relative Time Type</title>
<para>
The default time type for log events, a relative time type simply
means that the event is assumed to have a start time of whenever
the previous event ends (if it has a
<computeroutput>PLAY</computeroutput> or
<computeroutput>SEGUE</computeroutput> transition)
or whenever it is started (if it has a
<computeroutput>STOP</computeroutput> transition).
</para>
</sect2>
<sect2 xml:id="sect.rdlogedit.the_hard_time_type">
<title>The Hard Time Type</title>
<para>
A hard time type causes the event to be executed or otherwise acted
upon when the wall clock equals the time associated with the event.
Hard times are a powerful feature that can be used to synchronize
the log to various external events. An event can be assigned a
hard time by clicking the <computeroutput>Start at</computeroutput>
check box in the Edit Log Entry
and filling in the desired time, and will show up with the letter
<computeroutput>T</computeroutput> appearing at the beginning of
its listed time in the
<computeroutput>Time</computeroutput> column of the Edit Log dialog.
</para>
<para>
The specific action that is performed when the time matches is
determined by the option parameters supplied as part of the event.
Three basic actions are possible:
</para>
<para>
<itemizedlist>
<listitem>
Start the event immediately
</listitem>
<listitem>
Cue to the event (&quot;Make Next&quot;)
</listitem>1
<listitem>
Wait up to some period of time, then start the event
</listitem>
</itemizedlist>
</para>
<sect3 xml:id="sect.rdlogedit.start_immediately">
<title>Start Immediately</title>
<para>
As implied by the name, if the event is set to start immediately,
it will be started as soon as the hard time is reached. Any
currently playing events in the log will be simultaneously
stopped down.
</para>
</sect3>
<sect3 xml:id="sect.rdlogedit.cue_to_the_event___make_next___">
<title>Cue to the Event (&quot;Make Next&quot;)</title>
<para>
If set to 'Make Next', the event will be cued up to become the
next event to be executed in the log, bypassing any intervening
events in the log between the currently playing event and the
hard timed one. Any currently playing events are unaffected.
</para>
</sect3>
<sect3 xml:id="sect.rdlogedit.wait_up_to_some_period_of_time__then_start_the_event">
<title>Wait up to some period of time, then start the event</title>
<para>
Very similar to &quot;start immediately&quot;, with the
difference that, if one or more events are currently playing,
the log will wait up to the specified amount of time
before stopping them and starting the new event. If the currently
playing event(s) finish before the specified time period has elapsed,
then the event is started immediately.
</para>
</sect3>
</sect2>
<sect2 xml:id="sect.rdlogedit.estimated_vs__scheduled_start_times">
<title>Estimated vs. Scheduled Start Times</title>
<para>
When viewing log events in
<command>rdlogedit</command><manvolnum>1</manvolnum>, the displayed
start time style for each event can be either
<userinput>Estimated</userinput> or
<userinput>Scheduled</userinput>, as selected in the
<computeroutput>Show Start Times As</computeroutput> dropdown box.
<userinput>Estimated</userinput> will give start time values
based on any hard start times in the log, taking the known
lengths of the relevant carts, while <userinput>Scheduled</userinput>
will display the start times as provided by an external music and/or
traffic scheduling system.
</para>
<para>
The optimum style to use is largely dependent on how a particular
log was assembled. If the log was generated using
<command>rdlogmanager</command><manvolnum>1</manvolnum> and largely
populated with events from external music and traffic systems, the
<userinput>Scheduled</userinput> style will usually be preferred
as this permits the start times provided by those external schedulers
to be visible. On the other hand, if the log was mostly assembled
&quot;on the fly&quot; in
<command>rdlogedit</command><manvolnum>1</manvolnum>, the
<userinput>Estimated</userinput> style will usually provide more
insight on a log will actually time out when played.
