Yeah, you can see one major problem, there. In order to fit into the weird d tag rating superstructure, they put their nice a tag into the d tag. An index inside of another index.
I mean, I can just add the `o` and `a` tags, to be compliant with their kind number, but it's like a bug-fix.
searching by d tag is getting weird.
what are you evaluating books, people, git repositories?
I guess they used the d tag to get around having to define using the e or a tag, but that's just two lines of code.
And describing what you are identifying is easiest using a hierarchy.
I am identifying a publication. It is a book. It is friction. It is historical.
I am identifying a concept. It is a plan. It is for software. It is for testing.
I am identifying a place. It is a lake. It is in Europe. It is in Germany.
And so on. That also means that you can look for something, without knowing specifically what you are seeking, as each choice opens up more choices.
It's fiction, sorry. 😂
Another good example:
I am describing an applicance. It is for households. It is for kitchens. It is for dishwashing.
satlantis already has the data I don't know where, "external data and local research, combining hundreds of data points to create a snapshot of each destination" https://www.satlantis.io/place/ae/dubai/dubai/R4479752/scores
probably you can't create that amount of useful data without external sources.
I only know of the ISO codes for countries and regions. And zip codes within regions.
