# Datastore tuples

- [[202203080152 Entity Attribute Value]]
- [[zk/202203080153 Transactional Entity Attribute Value]]

#### What's the context?

I think where I was going with this is that each cell that gets entered into the knowledge graph is a tuple. I'm not sure that still makes sense.

## n-tuple

* Entity
  * Does a single string serve to identify this?
  * Maybe a "Name": {common name, id}
  * Can the ID be a UUID?
    * What about documents with a DOI? Does this matter?
* Attribute
  * Tempted to make this a string
  * What if every attribute is a Name?


```protobuf
message Name {
    string id = 1;      // e.g. a UUID
    string common = 2;
};

message Attribute {
    Name name = 1;
    Value value = 2;
}

message Transaction {
    int64 timestamp = 1;
};

message Fact {
    Name entity = 1;
    Attribute attribute =2;
    Value value = 3;
    Transaction transaction = 4;
    boolean retraction = 5;
};
```
