.me

Social Graph Walkthrough ​

This is the canonical .me example for public identity, structural privacy, semantic links, reactive derivations, and explainability in one flow.

It demonstrates:

  • identity declaration with @
  • public profile data
  • private wallet data with stealth root behavior
  • pointer-based friend relations
  • automatic derivations with =
  • private group/chat state
  • explain() for traceability

Full Script ​

ts
import ME from "this.me";

const me = new ME();

me["@"]("jabellae");

// Public profile
me.profile.name("Jose Abella");
me.profile.bio("Building the semantic web.");

// Private wallet
me.wallet["_"]("wallet-key-2026");
me.wallet.balance(12480);
me.wallet.savings(4500);

// Social graph
me.users.ana.name("Ana");
me.users.ana.age(24);
me.users.pablo.name("Pablo");
me.users.pablo.age(19);

me.friends.ana["->"]("users.ana");
me.friends.pablo["->"]("users.pablo");
me.friends["[i]"]["="]("isAdult", "age >= 18");

// Private group chat
me.groups.vancouver["_"]("group-key-2026");
me.groups.vancouver.topic("Trip to Vancouver");
me.groups.vancouver.members.count(4);
me.groups.vancouver.messages[0].from("jabellae");
me.groups.vancouver.messages[0].text("Who is bringing the car?");
me.groups.vancouver.messages[0].time("2026-04-10");

console.log(me("profile.name"));                    // "Jose Abella"
console.log(me("friends.ana.isAdult"));             // true
console.log(me("friends[age >= 18].name"));         // { ana: "Ana", pablo: "Pablo" }
console.log(me("wallet"));                          // undefined
console.log(me("wallet.balance"));                  // 12480
console.log(me("groups.vancouver"));                // undefined
console.log(me("groups.vancouver.messages[0].text"));
console.log(me.explain("friends.ana.isAdult"));

Why It Matters ​

Identity and public state ​

ts
me["@"]("jabellae");
me.profile.name("Jose Abella");
  • @ establishes the root identity.
  • Public paths like profile.name behave like normal semantic state.

Structural privacy ​

ts
me.wallet["_"]("wallet-key-2026");
me.wallet.balance(12480);
  • wallet becomes a secret scope.
  • me("wallet") returns undefined.
  • Deep leaves like me("wallet.balance") still resolve.

Graph edges without duplication ​

ts
me.friends.ana["->"]("users.ana");
  • friends.ana stores a pointer, not a copy.
  • Reads like me("friends.ana.age") traverse to the target path.

Reactive semantics ​

ts
me.friends["[i]"]["="]("isAdult", "age >= 18");
  • One declarative rule applies to every existing friend node.
  • Changing users.ana.age updates friends.ana.isAdult.

Explainability ​

ts
me.explain("friends.ana.isAdult");
  • Shows the derivation expression.
  • Shows the effective inputs used to compute the value.
  • Masks secret-origin inputs when required by scope rules.

Expected Reads ​

  • me("profile.name") -> "Jose Abella"
  • me("friends.ana.isAdult") -> true
  • me("wallet") -> undefined
  • me("wallet.balance") -> 12480
  • me("groups.vancouver") -> undefined
  • me("groups.vancouver.messages[0].text") -> "Who is bringing the car?"
