Proposal: Path collection

Inclusion mapping

• ↪ is the translingual symbol for embedding, inclusion maps (Wiki: embedding, inclusion map)
  • [↪] ↪ used as an annotation on a sub-node can be used to indicate this relation
  • Unicode code point U+21AA - noted henceforth in a machine-readable way as:
    • [U21aa]
  • ... a parser [i.e. computer program] can use this representation by:
    • transliterating the unicode code points to symbol
    • using a lookup service such as Wiktionary: https://en.wiktionary.org/wiki/%E2%86%AA

      • note that modern browsers do this in the background for ease of reading,

        ↪ the above link appears as .../wiki/↪ and is % encoded upon copy

Usage note

• In markdown [the format of these notes at time of writing], lists 'newlined' with 2 spaces will not be displayed differently by line-start spacing (list indentation), so either changing the symbol [incl. diacritics], repetition etc. could be used to differentiate (i.e. a sequence, or for a vector with direction, chain/antichain)
  • [ and ] are used as commands in the R programming language, for subsetting and act differently when repeated ([[), e.g.:

data.frame[1,1]

### Further reading

- The above symbol is categorised under [Translingual lemmas](https://en.wiktionary.org/wiki/Category:Translingual_lemmas)
- Other unicode code points in the same block are not annotated as such, making me wonder if it's been added by some ardent category theorist
  - see:  
    ↪ Wikipedia: [Category theory](https://en.wikipedia.org/wiki/Category_theory)  
    ↪ Wiktionary: [category theory](https://en.wiktionary.org/wiki/category_theory)  
    ↪ Wiktionary translingual ( _“mul”_ ) category: [Category theory](https://en.wiktionary.org/wiki/Category:mul:Category_theory)

## Path collection

- Set collection is simplest (tabulation) and connection is probably only some form of metadata
  - See: note on _source_ text as metadata ❧ `lmmx/queck` ∷ [Meta: Design: Entry storage](https://github.com/lmmx/queck/wiki/Meta:-Design:-Entry-storage)
    - [•] map =/= territory essentially, but territory being ground truth
- Collecting set of resources, some e.g. tweets, intrinsically 'point to' others within a set and can be assumed directed
  - [↪] † _“unto”, “upon”, “onto”, “over”_
  - [↪] ‡ _“about”, “around”_
  - ...
  - [•] parenthetical (as in circular _record_ symbol, square stop symbol)
    - [▪] to ignore for a moment the filled status and focus on geometry
    - cf. square parenthetical `[▪]`
    - [U`2022`]
  - [▪] square-parenthetical (as in square stop symbol, something that is 'a given')
    - cf. rounded parenthetical `[•]`
    - [U`25aa`]
  - [‣] `TODO:assign`
    - [U`2023`]
