Data licensing

The Open Data Hub provides open, freely accessible data under permissive licenses, ensuring compliance with open data principles. As an API user or ingestion creator, you can rely on structured license metadata to understand the terms under which data can be used.

1. License information in API responses​

The Content API includes a LicenseInfo block in every dataset response. This block provides key metadata about the licensing of the data record and is present for all publicly exposed data.

1.1. Structure of LicenseInfo​

The LicenseInfo object contains the following fields:

FieldTypeDescription
AuthorstringThe author of the data. May be empty.
LicensestringThe license type applied to the data (e.g., CC0, Proprietary).
ClosedDatabooleanIndicates whether the data is closed (true) or open (false).
LicenseHolderstringURL or identifier of the entity holding the license.
info

The LicenseInfo block applies only to the parent data node (the one identified by an Id). It does not extend to child nodes such as Streamurl or Webcamurl, which may link to external resources governed by different licensing terms.

1.2. Common license values​

  • CC0: The data is in the public domain and can be freely reused without restrictions.
  • Proprietary: The data is owned by a specific entity and may have usage limitations.

Only open data records are returned through the Content API. Even if source systems contain closed or proprietary data, these are filtered out during ingestion and not exposed in API responses.

1.3. Example LicenseInfo in a response​

{
  "Id": "D3659E1F111C4CDB2EC19F8FC95118B7",
  "Active": true,
  "Webcamurl": "https://webtv.feratel.com/webtv/?&pg=5EB12424-7C2D-428A-BEFF-0C9140CD772F",
  "LicenseInfo": {
    "Author": "",
    "License": "CC0",
    "ClosedData": false,
    "LicenseHolder": "https://www.lts.it"
  }
}

In this example, the LicenseInfo applies only to the parent record (e.g., the webcam metadata), not to the stream or image content accessible via Webcamurl.

2. Image licensing and availability​

Images associated with data records are subject to additional licensing checks. The Content API only includes images that are licensed under permissive terms.

2.1. Image license requirements​

  • Images must have a CC0 or CC-BY license to be included in API responses.
  • Images with no license (License == null) or a proprietary license (e.g., LTS) are excluded.

This filtering ensures compliance with open data standards. As a result, not all accommodations or points of interest include images in their responses.

2.2. Per-image license details​

When images are included, license information is provided in the ImageGallery object:

FieldTypeDescription
ImageUrlstringURL of the image.
LicensestringLicense type (e.g., CC0).
CopyRightstringCopyright notice, if applicable.
LicenseHolderstringEntity holding the license.

Example:

{
  "ImageUrl": "https://urltoanimage",
  "License": "CC0",
  "CopyRight": "© LTS",
  "LicenseHolder": "https://www.lts.it"
}

3. Access and usage considerations​

3.1. No authentication required​

Open Data Hub data can be accessed without authentication. You can make requests directly to the API endpoints.

warning

To avoid CORS errors in browser-based applications, always use https://opendatahub.com (not HTTP) when calling the API from JavaScript.

3.2. Company details as open data​

Company-related information such as names, addresses, and contact details are treated as open data and can be freely shared with third parties. These do not contain personal data and are published under open licensing terms.

4. Time series data licensing​

Licensing for the Time Series API applies at two levels:

  • Station data (the station catalog: identifiers, names, coordinates, and metadata) is generally published under CC0 for all stations.
  • Measurements are generally CC0 when the dataset is open. Measurements that belong to a closed dataset are proprietary and require authentication and the appropriate role to read.

To check whether a dataset is open or closed, see its ApiAccess value in the Metadata API or the Discovery tool.
