Datalayer

Data Layer

The Data Layer is the only component you, as the client, must implement. This layer stores and manages credential data securely within your infrastructure. The Client-Gateway communicates with the Data Layer over HTTP.

Responsibilities

Your implementation should support the following operations:

  1. Create: Add a new credential to the database.

  2. Import: Import an existing credential from external systems.

  3. Revoke: Mark a credential as revoked.

  4. Verify: Validate the status of a credential.

Example Implementation

You can implement the Data Layer using any database technology. Below is an example using MongoDB.

Setting Up MongoDB

  1. Install MongoDB on your infrastructure or use a managed service.

  2. Create a credentials collection.

Example Code

Here is an example of a simple Node.js service for the Data Layer:

const express = require('express');
const mongoose = require('mongoose');

const app = express();
app.use(express.json());

const CredentialSchema = new mongoose.Schema({
  credential_id: String,
  name: String,
  type: String,
  status: String,
  expires_at: Date,
});

const Credential = mongoose.model('Credential', CredentialSchema);

app.post('/create', async (req, res) => {
  const credential = new Credential(req.body);
  await credential.save();
  res.status(201).json({ success: true });
});

app.listen(5000, () => console.log('Data Layer service running on port 5000'));

Client should setup the datalayer URL on dashboard in order to gateway forward requests to the Data Layer for processing.
