is direct part of

The relationship between a part and a whole where the part has independent existence and there are no other parts in between.

Because the part has independent existence, there is no cascading delete.

It is safest to use this property when semantic directness is inherent in the relationship, rather than simply expressing a chosen granularity. For example, a spark plug is a direct part of an engine block; there cannot be any intermediate parts. Otherwise, there is a risk of making an isDirectPartOf assertion and then later inserting an intermediate part; this will result in making an asserted triple false even though there was no change in the world. When in doubt, use the transitive version gist:isPartOf.
