Ask HN: Simplest word to describe key/value store?

I am currently developing an app that uses customised key-value stores, but am struggling to come up with a simple way to describe this concept.

In the app, users can add custom meta data to objects. For example, a 'restaurant' object can contain metadata with , , and so on. Other another example would be a 'walking goal' object with custom meta data of and

I'm thinking of words like 'properties' or 'attributes', but I think the word/concept can be simplified further.

Thanks in advance!

Building is easy, naming is hard. In this case though, you're overthinking it. Pick one and move forward. Attributes is super common to use in these scenarios. Properties is also common and wouldn't be out of place.

I like to always build a project dictionary early on, as it just is helpful for everyone coming along later, and also if concepts change over time the original intent is clear. So like in this case, I'd just pick "attributes" and then have a markdown file or wiki etc that has common terms, and attributes would be described with examples. A quick 1-2 sentence write up is way easier then trying to spend a lot of time picking the perfect word/phrase.

Details?

Some languages use "dictionary".
