Failed to delete all triples of an example annotation via GUI #91

Closed arnikz closed 3 years ago

arnikz commented 3 years ago

Given an oa:Annotation instance, only its direct descendant nodes are deleted rather than all nodes of the annotation subgraph.

See also #2, #88 and #89.

Deleting annotations of MeasurementOrFact type (i.e., examples 4-6) leaves 5 triples over:

img:MMNAT01_AF_NNM001001033_003.jpg rdf:type oa:Source

The issue is with SPARQL DELETE query that doesn't handle the img:MMNAT01_AF_NNM001001033_003.jpg node(s) with more than one parent (BNodes).
