ChatGPT says 
"In Neo4j, categories are a way of grouping nodes based on shared properties or characteristics." (etc.)
But, as near as I can tell, categories are just nodes linked to other nodes. Have I missed something?
Is there any special syntax or semantics related to categories that don't apply to a generic node?
TIA,
Paolo
What is a category? Are you referring to Node labels, as labels are a form of classification.
@glilienfield , the term appears in various places in my travels. Here's an example:
SHOW FUNCTIONS
List all available functions, returns only the default outputs (name, category, and description).
I think from your answer, my suspicion is correct.

ChatGPT is confused. There is no concept of a "category" in Neo4j database. Maybe ChatGPT has found some articles on data modeling where someone is trying to model a "category" concept in their data. I see your post above 
In that case, you can check out the docs: SHOW FUNCTIONS - Cypher Manual - they will explain "category" in the context
Thanks, @john.stegeman,
I was confused by what I'd read before I asked ChatGPT. It was merely the cheeky definition.
But many thanks for your confirmation that "There is no concept of a "category" in Neo4j database." For me, that clarifies things immensely.
As a newbie, it's difficult to "sort the wheat from the chaff".
