| ☐ | Data | 2020-06-22 | The ontology seems somewhat confusing as to which items relate to digital data structures and which to the real-world information they represent. | In general, the data structures or data types should not be sub-classes of the corresponding information (an audio file format is not a sound) or the other way around (a picture is not an array of pixels), as the properties differ between the domains. They do however map to each other in certain respects, and they may have shared, intersecting sub-classes, especially with the commercial distribution of digital information products (e-books, streaming media services).

| ☐ | Hardware | 2020-05-24 | Clarify how instruction set architecture (Q272683) and instruction set (Q67185243) relate to each other | ||||
| ☐ | Operating system | 2020-05-24 | User interface asssumed to be a GUI | Add (or replace GUI toolkit or framework (P1414) with) input device (P479) to allow command-line interface (Q189053) | 2020-05-22 | ||
| ☐ | Operating system | 2020-05-24 | Unclear semantics of follows (P155) and followed by (P156) (issue pertains to other software as well) | ||||
| ☐ | Software | 2023-01-02 | Android (Q94) has been declared an instance of (P31) as well as a subclass of (P279) of mobile operating system (Q920890), apparently for the purpose of subdividing the product into further subclasses. | Normally an item should not be an instance of (P31) and a subclass of (P279) the same object, as it may have unexpected effects when property transitivity and value inheritance are implemented across Wikidata. Try to define a new ontology for items related to software and computer programs. |
