* Properties for which only a-nodes can exhibit
values:
Name: roleCastings
Value type: node set
Constraints on values: Only a-nodes exhibit values for this
property, and all a-nodes must exhibit a value for this property.
The value must be a set of c-nodes.
SIDP or OP?: SIDP
Semantics: The value is the node set which is the set of c-nodes
that serve as the C endpoints of the set of AC arcs of which the
a-node serves as the A endpoint.
Name: assertionType
Value type: node
Constraints on values: Only a-nodes exhibit values for this
property. The value must be a t-node.
SIDP or OP?: SIDP
Semantics: The value is the node, if any, that serves as the T
endpoint of the AT arc of which the a-node serves as the A
endpoint. If no value is exhibited, the assertion type of the
assertion of which the a-node serves as the nexus is unspecified.
Name: roleTypes
Value type: node set
Constraints on values: Only a-nodes exhibit values for this
property. The value must be a set of r-nodes.
SIDP or OP?: OP
Semantics: The value is the node set which is the set of r-nodes
that serve as the R endpoints of the set of RC arcs of which the
set of c-nodes serve as the C endpoints, which set of c-nodes
serve as the C endpoints of the set of AC arcs of which the
a-node serves as the A endpoint.
Name: players
Value type: node set
Constraints on values: Only a-nodes exhibit values for this
property. (There are no other constraints; any nodes can be
members of the node set.)
SIDP or OP?: OP
Semantics: The value is the node set which is the set of nodes that
serve as the x endpoints of the set of Cx arcs of which the set
of c-nodes serve as the C endpoints, which set of c-nodes serve
as the C endpoints of the set of AC arcs of which the a-node
serves as the A endpoint.
* Properties for which only c-nodes can exhibit
values:
Name: rolePlayer
Value type: node
Constraints on values: Only c-nodes exhibit values for this
property. There are no other constraints; any node can be the
value.
SIDP or OP?: SIDP
Semantics: This property may or may not exhibit a value. If it
does, the value is the node, if any, that serves as the x
endpoint of the Cx arc of which the c-node serves as the C
endpoint.
Name: roleType
Value type: node
Constraints on values: Only c-nodes exhibit values for this
property, and all c-nodes must exhibit a value for this property.
The value must be an r-node.
SIDP or OP?: SIDP
Semantics: The value is the node that serves as the R endpoint of
the CR arc of which the c-node serves as the C endpoint.
Name: assertion
Value type: node
Constraints on values: Only c-nodes exhibit values for this
property, and all c-nodes must exhibit a value for this property.
The value must be an a-node.
SIDP or OP?: SIDP
Semantics: The value is the node that serves as the A endpoint of
the AC arc of which the c-node serves as the C endpoint.
* Properties for which only r-nodes can exhibit
values:
Name: castingsOfRole
Value type: node set
Constraints on values: Only r-nodes exhibit values for this
property. All members of the node set must be c-nodes.
SIDP or OP?: OP
Semantics: The value is the node set which is the set of c-nodes
that serve as the C endpoints of the set of CR arcs of which the
r-node serves as the R endpoint.
* Properties for which only t-nodes can exhibit
values:
Name: assertionsOfType
Value type: node set
Constraints on values: Only t-nodes exhibit values for this
property, and all t-nodes must (by definition) exhibit a value
for this property. All members of the node set must be a-nodes.
SIDP or OP?: OP
Semantics: The value is the node set which is the set of a-nodes
that serve as the A endpoints of the set of AT arcs of which the
t-node serves as the T endpoint.
* Properties for which all kinds of nodes
(including but not limited to a-nodes, c-nodes,
r-nodes, and t-nodes) can exhibit values:
Name: rolePlayings
Value type: node set
Constraints on values: All nodes in the set must be c-nodes.
SIDP or OP?: OP
Semantics: The node set whose members are the c-nodes at the C
endpoints of the Cx arcs whose x endpoints are the node. If no
value is exhibited, then the node plays no roles in any
assertions.
* Properties for which only a-nodes, c-nodes,
r-nodes, and t-nodes can exhibit values:
Name: nodeType
Value type: enumeration
Constraints on values: Value must be one of "assertion", "casting",
"roleType", or "assertionType"
SIDP or OP?: SIDP
Semantics: Exhibits a corresponding value ("assertion", "casting",
"roleType", or "assertionType") when the node is an a-node,
c-node, r-node or t-node. When it exhibits no value, the node is
neither an a-node, nor a c-node, nor an r-node, nor a t-node.
