Figure 13-3 shows the relationship between a soft link, the object entry it points to, and
the resource that the object entry describes. The soft link, /.:/subsys/Print1, has an
attribute called CDS_LinkTarget, which contains the name that the link points to: an
object entry that is named /.:/subsys/PrintQ/server1. The object entry describes a print
server machine that is used by an application called PrintQ. The replica containing the
/.:/subsys/PrintQ/server1 object entry exists in the /.:/Paris_CH clearinghouse. The
object entry has an attribute called CDS_CHLastAddress attribute, whose Tower
subattribute contains RPC binding information that enables the PrintQ application to
contact the print server machine.
