Examples with RdfUri nl.knaw.huygens.timbuctoo.rml.dto.RdfUri used on opensource projects

Example 1 with RdfUri

use of nl.knaw.huygens.timbuctoo.rml.dto.RdfUri in project timbuctoo by HuygensING.

the class RmlMapperTest method createsExactlyAsManySplitOffsAsNecessary.

@Test
public void createsExactlyAsManySplitOffsAsNecessary() {
    /* given

      x dep y
      y dep a
      y dep y
      y dep z
      z dep x

      and unsortedList = [z, x, y, a]

      we expect exactly one splitOff for y (y') such that
      y dep a
      y' dep y
      y' dep z

      in a sortedList as follows: [a, y, x, z, y']

      before this test it was:

      y dep a
      y' dep y
      y'' dep z

      in a sortedList as follows: [a, y, x, z, y', y'']
