Data Stack Designer

Identify HK open data sources and design your data architecture

What This Node Does

Matches your project to specific Hong Kong government open data portals (DATA.GOV.HK, Transport Dept, EPD, etc.), identifies real-time vs. static data needs, and designs a data flow architecture from source to insight.

Role: Urban Data Stack Designer

Inputs

project_description	From initial input
project_domain	From initial input
problem_statement	From Problem Framer

Outputs

data_sources

HK government APIs/datasets, supplementary sources, data access methods, data flow architecture

How to Configure on Coze

01Create an LLM Agent node, name it "Data Stack Designer"

02Model: doubao-seed-2-0-lite-260215, temperature 0.3

03Paste the system prompt

04Define inputs: project_description, project_domain, problem_statement

05Define output: data_sources (string)

06Connect from Problem Framer (drag problem_statement edge)

Tips & Common Issues

Prioritize FREE and publicly accessible data — the node is configured for this

If government data doesn't cover your needs, the node suggests IoT sensors or crowdsourcing

Be specific about your domain — transport, environment, energy, building, or public service

The data architecture should be simple enough for a student prototype

Example

Input

Domain: transport. Problem: Students can't find parking at CUHK during peak hours.

Output

{"data_sources": "Primary: Transport Dept real-time parking availability API; DATA.GOV.HK traffic flow datasets (static, hourly). Supplementary: IoT ultrasonic sensors at parking bays (student-deployed prototype). Architecture: Transport API → REST polling (5min) → JSON storage → Availability calculator → User dashboard. Limitations: Transport Dept API may require registration; real-time sensor data requires hardware."}
