The class representing the collection of all the individuals declared in this ontology standing for world objects.
EMMO
[2,"smw-datavalue-wikipage-property-invalid-title","HasComment","'EMMO' is the disjoint union of 'Item' and 'Collection' (covering axiom).\nThe union implies that 'EMMO' individuals can only be 'Item' individuals (standing for self-connected world objects) or 'Collection' individuals (standing for a collection of disconnected items).\nDisjointness means that a 'Collection' individual cannot be an 'Item' individual and viceversa, representing the fact that a world object cannot be self-connected and non-self connected at the same time.@en"]
[2,"smw-datavalue-wikipage-property-invalid-title","HasComment","Mereotopology is the logical framework used by the EMMO ontologist to characterize the universe and to provide the definitions to connect world objects to the EMMO concepts.\nFor the EMMO ontologist the whole universe is the most comprehensive object. World objects are then sub-parts of the universe.\nThe fundamental distinction between world objects, upon which the EMMO is based, is self-connectedness: a world object can be self-connected xor not self-connected.\nParthood relations do not change dimensionality of the world object: every part of a world object is another world object and always retains a 4D dimensionality character.\nThe smallest part of a world object (i.e. a part that has no proper parts) is called a 'Quantum' individual. Quantum individuals are the fundamental causal constituents of the universe. They are no-dimensional, and their aggregation makes 4D objects emerge from their causal structure.\nIt follows that, for the EMMO, world objects of dimensionality lower than 4D (e.g. surfaces, lines) do not exist.\nIn the EMMO there are no relations such as occupiesSpace, since objects are themselves the 4D regions.\nAn object always possess 4-dimensions. It follows from the fact that perception is always unfolding in time (e.g. you always have an aperture time when you take a picture or measure a property. Instantaneous perceptions are idealizations (abstractions) or a very small time measurement).@en"]
