            Sparql query to get only top-most elements matching criteria
            Asked 2021-Sep-30 at 10:10

            I have multiple trees where nodes are linked with hasParent and each node has some particular color. I need to filter a tree by a color and extract the topmost elements (exclude nested elements after filtering).

            Here is an example of my data:

            The result I need is: [A, B, I].

            I know how to implement basic tree filter that returns [A, B, I, J, L, O]:
