The following cards are allowed on an event artifact:

<blockquote>
<b>C</b> <i>comment</i><br>
<b>D</b> <i>time-and-date-stamp</i><br />
<b>E</b> <i>event-time</i> <i>event-id</i><br />
<b>P</b> <i>parent-artifact-id</i>+<br />
<b>T</b> <b>+</b><i>tag-name</i> <b>*</b> <i>value</i><br />
<b>U</b> <i>user-name</i><br />
<b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br />
<b>Z</b> <i>checksum</i>
</blockquote>

The C card contains text that is displayed on the timeline for the
event.  Exactly one C card is required on an event artifact.

40-character lower-case hexadecimal string.

The option P card specifies a prior event with the same event-id from
which the current event is an edit.  The P card is a hint to the system
that it might be space efficient to store one event as a delta of the
other.

An event might contain one or more T-cards used to set
[./branching.wiki#tags | tags or properties]
on the event.  The format of the T-card is the same as
described in <i>Control Artifacts</i> section above, except that the
second argument is the single characcter "<b>*</b>" instead of an
artifact ID and the name is always prefaced by "<b>+</b>".
The <b>*</b> in place of the artifact ID indicates that
the tag or property applies to the current artifact.  It is not
possible to encode the current artifact ID as part of an artifact,
since the act of inserting the artifact ID would change the artifact ID,
hence a <b>*</b> is used to represent "self".  The "<b>+</b>" on the
name means that tags can only be add and they can only be non-propagating
tags.  A an event, T cards are normally used to set the background
display color for timelines.

The optional U card gives name of the user who entered the event.

A single W card provides wiki text for the document associated with the
event.  The format of the W card is exactly the same as for a wiki 
artifact.

The Z card is the usual checksum over the rest of the attachment artifact.
