REF: parid2292

TXT: As in "C-node": casting. The subject of every c-node is a "casting" 
(see [parid2139] 2.14) of a role player in a role.

FIX: Used in "'C' endpoint," "AC arc," "CA arc," "CR arc," "RC arc," "Cx 
arc," "xC arc" as a synonym for c-node. See, c-node.
COM: Neeless repetition of the c-node definition and only part of that.

REF: parid2263

TXT: As in "AC arc", "CR arc", or "Cx" arc: casting. The node that 
serves as the C endpoint of an AC, CR, or Cx arc is a c-node.

FIX: Strike.
COM: No longer needed with reformed parid2292.

REF: parid2137

TXT: A "casting" node. The subject of a c-node is the fact that a 
specific role player (or the fact that no role player) plays a specific 
role in the relationship that is stated by the unique assertion of which 
it is a component.

FIX: The node that associates a role in an assertion with a particular 
role player, if any.
COM: Removed starting short sentence. Removed "unique" assertion 
language. Removed repitition of the term being defined.

REF: parid2143

TXT: A c-node serves as one of the endpoints of one AC and one CR arc. 
It may or may not serve as the C endpoint of a Cx arc. Like all nodes, 
it may serve as the x  endpoint of of any number of Cx arcs. It cannot 
serve as any other endpoint types.

FIX: Behavior: Serves as the C endpoing of AC, CR and Cx arcs. May serve 
as x endpoint of any Cx arcs.
COM: Simplified explanation. The "may or may not serve as C endpoint..." 
and "one of the endpoints of one AC and one CR arc" are comments on the 
structure of an assertion. Not relevant to definition of behavior of 
c-node, is relevant to defining structure of an assertion. "It cannot 
serve as any other endpoint types." is superfluous. The definition says 
what arcs it can serve as an endpoint and the point should not be belabored.

REF: parid2146

TXT: A value of a property of a node that is not built-in, but instead 
is assigned to the property on account of the node's situation in the 

FIX: Value assigned to a property of a node based upon the node's 
situation in the graph.
COM: Eliminated reference to built-in.

REF: parid2151

TXT: connectedness

FIX: strike
COM: Replaced by edge.

REF: parid2152

TXT: A primitive relationship between two nodes: an arc. (Cf. "assertion".)

FIX: Strike
COM: Replaced by edge.

REF: parid2264

TXT: The word "connectedness" consistently denotes the significance of 
an arc, while the word "relationship" denotes the significance of an 
assertion. This terminological convention emphasizes the distinction 
between the relationships specified by arcs vs. the relationships 
specified by assertions. The relationship specified by arcs have no 
proxies (i.e., they are not and cannot be reified by nodes in situ), 
even though, in an absolute sense, the relationships specified by arcs 
are subjects like any other subjects. In discussions of Topic Maps, the 
word "relationship" is reserved to denote only the relationships that 
are reified by assertions; it is never used to denote the relationships 
that are represented (and not reified) by arcs. Arcs are merely 
components of assertions; they are parts of the backstage machinery of 
assertions -- machinery which is normally hidden from end users. The 
machinery of assertion representation is best understood as being 
capable of reifying in situ all relationships except for the 
"connectednesses" (arcs) of which the machinery itself consists.

FIX: Strike.
COM: Replaced by edge. Briefly the edge terminology allows the reader to 
distinguish between the roles a set of endpoints play in a particular 
assertion, represented by the various arcs, and an unreified 
relationship between the two nodes. The edge allows us to speak of 
reifying such a relationship, as distinguished from the arcs which are 
peculiar to a particular assertion.

REF: parid2155

TXT: parid2155] A connectedness between two nodes, with a c-node as one 
endpoint and a r-node as the other endpoint. A CR arc specifies that a 
specific role (the subject of the r-node) is the role that is being 
played in the casting (the subject of the c-node) of a specific role 
player in that specific role in a specific assertion.

FIX: An arc with an c-node as one endpoint and a r-node as the other 
COM: Removed connectedness, see definition of edge below. Further 
removed defining of the parts of the definition. The c-node and r-node 
references should lead readers to the definitions of those items. Helps 
prevent confusing and perhaps inaccurate restatement of the definitions 
for those items.
