Subject areas edit
Alphabetical any easily in information is most order sorted understood when.
Current work edit
Class logic edit
The distinction between class and instance is not always clear. Here is a rule of thumb that may work (not sure if it applies in every language):
- Nurse is a profession (an instance of profession).
- Health worker is also an instance of profession.
- A nurse is a health worker (a subclass of health worker).
Try moving the indefinite article around and see what happens. "A nurse" refers to a member of the nurse group, while "nurse" refers to the group as a whole. A few more examples:
- Road is an infrastructure (an instance of infrastructure).
- Transport route is also an instance of infrastructure.
- A road is a transport route (a subclass of transport route).
- Square is a shape (an instance of shape).
- Rectangle is also an instance of shape.
- A square is a rectangle (a subclass of rectangle).

Nematode infections edit
Quite an interesting case of confusion:
| Item | History | Wikipedia | Wikipedia quotes | |
|---|---|---|---|---|
| Subclass of | Selected properties | |||
| ancylostomiasis (Q14623417) | ||||
| (no subclass) | ||||
| ancylostomiasis (Q11679861) |
|

| necatoriasis (Q4118581) |

| ancylostoma duodenale ancylostomiasis (Q137597) |
| |||
| hookworm disease (Q5898175) | ||||
| nematode infection (Q2072680) | ||||
| parasitic helminthiasis infectious disease (Q578994) | ||||
Legend for the Wikipedia column:

_?_
|
Article is too brief, unclear, or difficult for me to translate even with Google Translate to reliably determine its subject |
The only languages with articles for all three interrelated items are Arabic, English, and Russian (plus Kirghiz for the two mutually confused articles only), where the Russian article disagrees with the English one on its subject and (I think) also the Arabic one, but this is not a simple majority point of view issue, and there may have been many changes and "corrections" done to the items by editors who have been unaware of the disputable linking of either language edition. Let's not disappoint those editors who were correct in the first place by unnecessarily redefining the items according to what topics may have been inferred later.
So this is apparently why there was a subclass loop between ancylostomiasis (Q11679861) and ancylostoma duodenale ancylostomiasis (Q137597) in the first place. After my initial attempt to resolve the loop by removing one of the subclass links was reverted, I found myself creating this table simply to figure out why we had different opinions on which subclass link should be removed. Thanks to User:Infovarius for drawing my attention to the confusion!
For additional reference, here are the associated nematode species
| Item | History | Wikipedia | Wikipedia quotes |
|---|---|---|---|
| Subclass of | Selected properties | ||
| Ancylostoma duodenale (Q2520810) | |||
| (not a subclass) | |||
| Necator americanus (Q2433913) | |||
| (not a subclass) | |||
| Ancylostomatidae (Q3093248) | |||
| (no subclass) |
And I need to work on my table design skills as well...
Lexical reference edit
| Shorthand | Description | Latin term or grammatical feature | English | Russian |
|---|---|---|---|---|
| ancylostomatidae | = Latin | = Latin | ||
| AD | ||||
| ADA | ||||
| NA | necator americanus |
Planned resolution edit
When the above analysis is finished, here is what should be done (plan to be further refined as potential issues emerge):
- Spell out which item should serve what purpose, where unclear
- Move away those interwiki links and other item properties that don't belong with either of the items being revised
- Delete or rectify properties (including labels and descriptions) that are in error, or will be in error after the revision
- Move
