Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag. ### Cloneable Template Object - Kind: [constraint](https://banes-lab.com/records/kind/constraint.md) - Category: [Creational Patterns](https://banes-lab.com/ontology/lexicon/lexicon-category-creational-patterns.md) - Layer: [Design Patterns Core](https://banes-lab.com/records/layer/design-patterns-core.md) Details Definition The requirement that a prototype object support being copied to produce new instances.
