Fuseki system identifiers for blank nodes - RDF Patch

[edmondchuc]

Hi, I'm trying to figure out whether Fuseki provides a way to retrieve the system identifiers for blank nodes like in GraphDB.

The reason why I want the system identifiers is to be able to generate an RDF Patch log entry to update the values for blank node objects in a Fuseki system. The docs for RDF Patch describe updating values within blank nodes by referring to the system's identifier.

Is my use case supported? Or is there another way to achieve the same result without using SPARQL Update? Thanks.

In Fuseki str(?myBlankNode) will return the internal identifier as a string.
It's not a portable - it is an extension.

Otherwise use SPARQL Update - that is portable.

Perfect, thanks for the quick response @afs!
