Dictionaries and encyclopedias also use singular. Why? Because:
- they don’t describe collections
- their entries are terms/lemmas
Likewise:
- the entries in knowledge graphs:
- are not tables (like in databases)
- they may contain tables, but they are not tables themselves
- are concepts
- are not tables (like in databases)
- each Logseq page:
- should not be an index
- it may contain indices, but it is not an index itself
- should outline a concept
- should not be an index
