  The present preprint specifies and defines all Terms, Properties,
Relationships and Axioms of TestTDO (software Testing Top-Domain Ontology)
v1.3, which is a slightly updated version of its predecessor, TestTDO v1.2.
TestTDO is a top-domain ontology built in the context of a four-layered
ontological architecture named FCD-OntoArch (Foundational, Core, and Domain
Ontological Architecture for Sciences). This is a four-layered ontological
architecture, which considers Foundational, Core, Domain and Instance levels.
In turn, the domain level is split down in two sub-levels, namely: Top-domain
and Low-domain ontological levels. Ontologies at the same level can be related
to each other, except for the foundational level where only the ThingFO
ontology is found. In addition, ontologies' terms and relationships at lower
levels can be semantically enriched by ontologies' terms properties and
relationships from the higher levels. Some TestTDO's terms and are extended
primarily from SituationCO (Situation Core Ontology), and ProcessCO (Process
Core Ontology) concepts. Stereotypes are the mechanism used for enriching
TestTDO terms. Note that annotations of updates from the previous version
(v1.2) to the current one (v1.3) can be found in Appendix A.
