[sc34wg3] RM: C, c-node, conferred [property] value, connectedness, CR arc
Mon, 24 Feb 2003 12:47:01 -0500
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.
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.
COM: No longer needed with reformed parid2292.
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.
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.
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.
COM: Replaced by edge.
TXT: A primitive relationship between two nodes: an arc. (Cf. "assertion".)
COM: Replaced by edge.
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.
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.
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.
