         The workspace supports the notion of markers on arbitrary
resources.  A marker is a kind of metadata 
(similar to properties) which can be used to 
tag resources with user information.  Markers are 
optionally persisted by the workspace whenever a 
workspace save or snapshot is done. 
&lt;p&gt;
Users can define and query for markers of a given type.  
Marker types are defined in a hierarchy that supports 
multiple-inheritance.  Marker type definitions also 
specify a number attributes which must or may be 
present on a marker of that type as well as whether 
or not markers of that type should be persisted. 
&lt;p&gt;
The markers extension-point allows marker writers to 
register their marker types under a symbolic name that 
is then used from within the workspace to create and 
query markers. The symbolic name is the id of the 
marker extension. When defining a marker extension, 
users are encouraged to include a human-readable value 
for the &quot;name&quot; attribute which indentifies their marker 
and potentially may be presented to users.

         Following is an example of a marker configuration: 

&lt;p&gt;
&lt;pre&gt;
   &lt;extension id=&quot;com.xyz.coolMarker&quot; point=&quot;org.eclipse.core.resources.markers&quot; name=&quot;Cool Marker&quot;&gt; 
      &lt;persistent value=&quot;true&quot;/&gt; 
      &lt;super type=&quot;org.eclipse.core.resources.problemmarker&quot;/&gt; 
      &lt;super type=&quot;org.eclipse.core.resources.textmarker&quot;/&gt; 
      &lt;attribute name=&quot;owner&quot;/&gt; 
   &lt;/extension&gt; 
&lt;/pre&gt;

         All markers, regardless of their type, are instances of 
&lt;samp&gt;org.eclipse.core.resources.IMarker&lt;/samp&gt;.

         The platform itself has a number of pre-defined 
marker types. Particular product installs may 
include additional markers as required.
