Blank nodes: some more
remarks
-
Blank nodes require attention when merging
-
- blanks nodes with identical nodeID-s in different
graphs are different
- implementations must be careful with their naming schemes when
merging
-
Many applications prefer not to use blank nodes and define new
URI-s “on-the-fly”
-
- eg, when triples are in a database
-
From a logic point of view, blank nodes represent an
“existential” statement (“there is a resource such that…”)
