Step-by-Step Guide

Follow these steps to publish wind turbine data in the ARC Dataspace

Prerequisites & Registration

Ensure you have access to the required systems

Register at Auth Portal: https://authportal.dataspace2.imsi.athenarc.gr/ Create an account and obtain authentication credentials. For demo purposes you can either request an account or use the default user provided by us (and so no registration is needed).
Access to EDC Connector (Provider): https://edc.dataspace2.imsi.athenarc.gr/ Your connector for publishing data assets
Prepare Wind Turbine Data: CSV format with sensor readings (temperature, RPM, power generation, etc.)

Create a Data Asset

Publish your wind turbine sensor data as an asset

Navigate to your EDC connector dashboard
https://edc.dataspace2.imsi.athenarc.gr/
Go to "Assets" section Click on "Create Data Offer"
Configure Asset Metadata:
- Asset ID: wind-turbine-sensor-data-2025
- Asset Title: Wind Turbine WTG-01 Sensor Data
- Description: Time-series sensor data from wind turbine including generator RPM, temperatures, and power output
- Content Type: text/csv
- Keywords: wind energy, predictive maintenance, sensor data, time-series
Specify Data Location: Source Data URL: Point to your CSV file location (HTTP endpoint, S3 bucket, or file path). For demo purposes Google Drive can be used. Method: GET/POST/etc.
Add Data Properties:
- Temporal coverage (date range of data)
- Spatial location (wind farm coordinates)
- Update frequency
- Data quality indicators
Save the Asset

Define Access Policies

Set usage rules and access controls

Navigate to "Policies" section
Create a Contract Policy:
- Policy ID: wind-data-access-policy
- Type: Contract Policy
- Permissions: USE (allow data transfer)
- Constraints: (optional)
  - Time-based access
  - Purpose limitation (e.g., "research only")
  - Consumer Participant ID restrictions
Save the Policy

💡 Tip: There is already defined policy of "always-true", only for demo purposes.

Create Contract Definition

Link your asset with the access policy

Go to "Contract Definitions"
Create New Contract Definition:
- Contract ID: wind-turbine-contract-def
- Access Policy: wind-data-access-policy (from Step 3)
- Contract Policy: wind-data-access-policy
- Asset Selector: wind-turbine-sensor-data-2024 (from Step 2)
Save the Contract Definition

💡 Tip: The contract definition makes your asset discoverable and negotiable by consumers

Verify Asset is Discoverable

Confirm your data appears in the catalog

Open KnowDS Discovery Portal: https://arc.knowds.imsi.athenarc.gr/
Search for your asset: Use keywords like "wind turbine", "WTG-01", or your asset name
Verify asset details:
- Check metadata is correct
- Confirm description is clear
- Ensure proper categorization

✅ Success! Your wind turbine data is now published and ready for consumers to discover and request access

Monitor Data Transfers

Track who is accessing your data

Catalog Browser: Search the catalog for data offers based on the connector endpoint provided.
Check "Transfer History" section in EDC: View active and completed data transfers
Review "Contracts" section: See negotiated contracts and their terms
