Description Help

Describe what this item represents. Recommended. Less than 64K characters. No formatting.

Category: "Category" is for groups of things, for concepts, and for the upper levels of hierarchiesHelp. (Though a hierarchy made up entirely of concepts could be all Categories.) Categories can "contain" other categories and/or individuals.
Individual: "Individual" is for specific, concrete things. Individuals can "contain" other individuals, but cannot contain categories. ("Ford Model-T" might be an individual, but could still contain parts that are also individuals, like "Windshield" and "Tire".)
Property: "Property" is used to define relationshipsHelp between other items. Once you create a new Property itemHelp, you should create one or more connectionsHelp that relate that property to other existing properties. In general, you will use the "sub_property_of" property in order to create these connections. For example, if you were creating a description of famillial relations between people, you might create a new property named "spouseOf". To define what the creation of connections using this new property means, you can create the connection "spouseOf sub_property_of symmetric_relationship". This example will cause "spouseOf" to be treated as a "peer" relationshipHelp (rather than a hierarchical one), and as a symmetric relationshipHelp, so that creating a "spouseOf" connection from one item to another implies an connection going the other direction even if it is not defined explicitly.
