BlankNodeId (Apache Jena)

java.lang.Object
- org.apache.jena.graph.BlankNodeId

```
public class BlankNodeId
extends java.lang.Object
```
System identifier for a blank node. Blank nodes have identity (you can .equals them apart) but no external stable identifier like a URI.
Databases need a persistent identifier for blank nodes - BlankNodeId.
The equivalent concept for the API is AnonId. Historically, that has been in the org.apache.jena.rdf.model package.
This id is guaranteed to be globally unique.
