Data "smushing" with 10g Spatial

573472Apr 20 2007 — edited Jan 6 2009
Are there any functions or methods for merging properties of RDF nodes that have distinct RDF ID's but actually represent the same entity?

With other tools that provide OWL support, for example, one can define a rule that will check for specific unique properties of a node and assign owl:sameAs property to two nodes that match. This partially gets us there by at least labeling nodes that are equivilent. However, one is left to provide code that "smushes" or aggregates the properties of these two nodes and removes the redundant node.

So, my question is: Does Oracle Spatial 10g provide some way to merge node that represent the same entity, either by attaching a preprocessing method to the data import step or on-the-fly in queries?

Thanks!

I have the same error simply by deploying ORDS on Tomcat locally. I'm using ORDS (21.1.3.153.1102) and Tomcat (10.0.11) installed on windows 10.

I never found the solution for the issue, but I believe it was related to Tomcat 10.x. I downgraded Tomcat to version 9 and the error went away.

Yes, ORDS will absolutely NOT work on Tomcat 10 today.
