2020 UPDATE: Please note that the open-source project DTPR is now independent of Sidewalk Labs and being stewarded by Helpful Places and an emerging coalition of partners and collaborators. For more information on the DTPR standard, please see this external website. For the most current Github repo, please see https://github.com/helpful-places/dtpr/

Designing for Digital Transparency in the Public Realm

Digital Transparency in the Public Realm is a project that seeks to facilitate the co-creation of prototypes that can advance digital transparency and enable agency in the world's public spaces.

With cities increasingly embracing digital technology in the built environment, we believe people should be able to quickly understand how these technologies work and the purposes they serve. We believe that creating a unified visual language will be a critical starting point, and that digital tools could help people to follow up and learn more.

Expert groups came together in cities around the world in co-design sessions to collaborate and prototype an initial set of open standards for digital transparency in the public realm. These standards, as well as all the workshop activities and materials that generated them, are publicly and freely available for others to adopt, use, and build upon.

We’re looking for partners who want to advance the use and adoption of these standards in the public realm. Please get in touch at dtpr-hello@sidewalklabs.com.

The DTPR Design Patterns and Prototypes - V1

There are four major components to DTPR - icons, a signage system, and a digital channel for communication - which together, help visualize and convey a taxonomy of key concepts.

Icons

You can download the icon files and visual system from Github.

Design Guide

The design guide has what you need to know in order to actually create signs using the icons or add the icons to existing signage.

Taxonomy

The taxonomy is the full set of definitions on which the icons are based. These definitions are also used in the prototype of the digital channel. The initial draft of the taxonomy and the associated icons are managed in an Airtable, which you can see here, and in the tables below.

Prototype for the Digital Channel

When you scan a QR code on a sign, it brings you to a webpage where you get more information. You can see our prototype for the digital channel - it’s currently set up for 307, Sidewalk Labs’ Toronto office and experimental workspace. Here’s the source code.

Co-Design Kit

In the course of developing the initial prototypes, we developed materials and a facilitation guide that was used to run our co-design sessions. All the materials are provided here so that anyone, anywhere, can take up these tools and use them to engage in this crucial topic.

Contributors

The development of these design patterns and prototypes would not have been possible without the large number of contributors who invested their expertise and time in this project. They are listed here.

Data Process

Icon	Technology	Description
	RDUA Approved	Data activity has undergone a Responsible Data Use Assessment and determined to provide a net benefit. The RDUA is a process that Sidewalk Labs conducts prior to the start of any data activity.
	Reviewed Internally	"Many organizations have internal review processes that consider the potential benefits, risks and implications for privacy for new technologies or data collection activities. For example, in Canada, Privacy Impact Assessments are often conducted by organizations prior to the beginning for a project - find out more [here] (https://en.wikipedia.org/wiki/Privacy_Impact_Assessment). This could be customized with the details of the accountable entity responsible for these instances of technology in the public realm
	Encrypted	Data has been encoded so that only authorized parties can access it, which can reduce risk related to handling private or sensitive information. Find out more [here] (https://en.wikipedia.org/wiki/Encryption)
	Aggregated	"Data that has been grouped or summarized from individual measurements, for example to count up totals or to calculate an average. Find out more [here] (https://en.wikipedia.org/wiki/Aggregate_data)
	Raw data	"Data that has not been processed or altered from the point of collection - the data is effectively identical to how it was gathered from the original data source. Find out more [here] (https://en.wikipedia.org/wiki/Raw_data)
	Regulated	Depending on the jurisdiction and type of data, data is regulated in various ways. For example, Personal Information in Canada is regulated by federal, provincial, and municipal laws. The collection, use and disclosure of Personal Information by private companies in Ontario is regulated by the [Personal Information Protection and Electronic Documents Act] (https://www.priv.gc.ca/en/privacy-topics/privacy-laws-in-canada/the-personal-information-protection-and-electronic-documents-act-pipeda/) This should be customized for the jurisdiction where this digital channel is being used
	AI System	Data that is processed by automated, algorithmic or artificial intelligence systems to derive a new result or data point. Find out more about [automated] (https://en.wikipedia.org/wiki/Automated_decision_support), [algorithmic] (https://en.wikipedia.org/wiki/Algorithm) and [artificial intelligence] (https://en.wikipedia.org/wiki/Artificial_intelligence) systems.
	De-identified	Data that is processed to remove identifying values, usually to protect privacy. De-identification can happen at any point in a data collection process, for example before it is stored in a database, or before it is published. Here we define it to mean after the data has already left a hardware device, or after it has been stored in a database. Find out more [here] (https://en.wikipedia.org/wiki/De-identification)
