Frequently asked questions

Find answers to common questions about openJII and how to get started.

Did you find a bug or want to request a function?

If the bug is a security vulnerability, please do not follow the steps below but refer to our security policy.

How to report a bug

Ensure the bug was not already reported by searching the Github issues list.

If you can’t find an open issue addressing the problem, log in at GitHub and open a new bug report.

Include:

• Clear title and description

• As much relevant information as possible

• Code sample or test case demonstrating the issue

• Version of openJII you’re using

How to request a function

Please use request features (aka “Ideas”).

You can contribute code, documentation, or ideas through our GitHub repository or by joining the open science working group.

What kind of data are we collecting?

We collect measurements related to photosynthesis, such as chlorophyll fluorescence, CO₂ assimilation, leaf temperature, or environmental parameters (light intensity, humidity, etc.). Currently, our platform only supports MultispeQ measurements, but in the future also other sensors. If your device is not listed and you want to connect it to openJII, please contact us at openjii@jii.org.

How is this different from other photosynthesis research tools?

Unlike closed research systems, the openJII platform makes data openly available (with user consent), encourages collaboration, and supports multiple devices and apps for field and lab data collection.

Is openJII free of charge?

Yes, openJII is free of charge. openJII receives sufficient funding to maintain and operate the platform. Donations are however welcome to support open science and openJII.

If you want to contribute or support the platform, or see opportunities to include openJII in your project proposal, you can contact us at openjii@jii.org.

Can I include openJII in my project proposal?

Yes, you can include openJII in your project proposal by referring to openJII.

If you need support from us for your project like:

• Including new sensors to the platform or type of data

• Data analyses and modelling

• Training and expertise

Please contact us at openjii@jii.org for partnerships.

Who owns the data I upload?

You retain full ownership of your data. By contributing to the platform, you agree to share it under an open license. There is the option to mark your project/experiment data as private or embargoed for a maximum of 12 months. This complies with public available grant agreements.

How is my data shared with others?

You can set the visibility of your data to Private or Public. Public datasets are directly visible to all registered users and can be cited. Private datasets can be embargoed for a maximum of 12 months before getting public. This is an automated process and the period cannot be extended.

How is data protected or anonymized?

We store all data on secure European servers, following EU GDPR standards. Stored data may include GPS coordinates and other personal information. Personal identifiers such as GPS of private property, are not masked only embargoed if indicated.

By default, public datasets are shared under a Creative Commons Attribution (CC-BY-SA 4.0) license.
