+#### 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;
+};
+```
