Fig. 5.6 MMTO relation hierarchy, version 1.3.1, showing the subsumption (arrows) of relations
from the MMTO (rectangles) under relations from OSMO (hexagons), the EVMPO (rounded boxes)
and VIPRS (ellipses)
The relational alignment, which is shown for the MMTO in Fig. 5.6 and for the
examples from Chap. 3 in Table 5.2, is implemented directly in the domain ontology
TTL files, which contain statements by which the domain ontology relations are
subsumed under VIPRS relations. Property chain correspondences are applied when
the mereosemiotic chain relations from VIPRS are unfolded, cf. Fig. 5.7, yielding
series of elementary parthood and reference relations from the EMMO, so that the
graph grows both in terms of vertices and edges; in TTL notation, this corresponds
to the introduction of blank nodes (individuals without an IRI [41]) by which, e.g.
:I viprs:mereosemiotics_hp_ip_is :J.
which encodes (:I, :J) :
