| | Artifact |
 | | An artifact kind identified by a common description or concept can include several subtypes or species; for example, there are different paper clip types for which their authors (that is, their inventors) obtained separate patents; these fall under the more general artifact kind ‘paper clip’. |
 | | Many artifacts are characterized by means of their intended function and use, and some parts of complex artifacts are artifacts (we might call them “sub-artifacts”) which have been designed to serve a certain function in a given principal artifact. |
 | | Artifacts in the wide sense form an ontologically heterogeneous collection: some of them have instances (literary works and musical compositions), others are singular objects (e.g., paintings), and there are also abstract artifacts, for example, fictional characters, which have authors but are neither concrete particulars nor have such particulars as instances. |
