Standards are essential for Smart City technology and business development. Standards benefit vendors, cities, and users. For vendors, standards unify markets and mean that a larger market can be addressed with a single product design, allowing products to more efficiently make returns on the investments needed to develop them. For cities, standards allow the deployment of technologies that can be sourced from multiple vendors, more and higher quality products, and increases the probability that systems will remain usable over a longer timescale. Standards also encourage the development of open systems that can interoperate with other standardized systems, multiplying the number of use cases that can be addressed. For users, standardized technologies mean that services available in one city will also be available in others, facilitating mobility.

However, we need to know what standards should be developed to achieve these objectives. What gaps exist? What opportunities can be exposed by standards that enable new use cases? What are the business drivers that encourage adoption of standards, and how can standard development be aligned with these drivers? Given a set of standards that could be developed, what are the priorities? How can the needs and goals of all stakeholders be aligned?

The purpose of this Interest Group is collect and connect Smart City stakeholders to answer these kinds of questions and drive the development of web technology standards aligned with the real needs of Smart Cities.

The topics that the Interest Group will address include but are not limited to:

The tasks that the Interest Group will undertake include:

Out of Scope

The technical development of standards is not in scope for the Interest Group. Technical discussions are expected to take place within a new or existing W3C Working Groups, or within a Community Group or Business Group when incubation is needed.


The primary deliverables of the Smart Cities Interest Group will be IG Notes that identify requirements for existing and/or new technical specifications and gaps. The group will also maintain public documentation of W3C Recommendations, standards, and technologies applicable to Smart City use cases that it is tracking and investigating. This documentation will include identified gaps, stable standards deployed in implementations, descriptions of proof-of-concept projects, and standards under development in W3C and external groups.

Normative Specifications

The Interest Group will not deliver any normative specifications.

Other Deliverables

Other non-normative documents may be created such as:

  • Use case and requirement documents;
  • Primer or Best Practice documents to support Smart City stakeholders.


Put here a timeline view of all deliverables.

  • Month YYYY: First teleconference
  • Month YYYY: First face-to-face meeting
  • Month YYYY: Requirements and Use Cases for FooML
  • Month YYYY: FPWD for FooML
  • Month YYYY: Requirements and Use Cases for BarML
  • Month YYYY: FPWD FooML Primer

Success Criteria

The Interest Group will have succeeded if it can achieve the following:

To achieve this, the Interest Group will organize regular conference calls to update members on progress of work items, and to invite other groups and organizations to present their work to Interest Group participants.


For all deliverables, this Interest Group will seek horizontal review for accessibility, internationalization, performance, privacy, and security with the relevant Working and Interest Groups, and with the TAG. The Interest Group is encouraged to engage collaboratively with the horizontal review groups throughout development of each deliverable.

To be successful, this Interest Group is expected to have 6 or more active participants for its duration. The chairs and editors are expected to contribute half of a working day per week towards the Interest Group. There is no minimum requirement for other Participants.

The group encourages questions, comments and issues on its public mailing lists and document repositories, as described in Communication.

The group also welcomes non-Members to contribute technical submissions for consideration upon their agreement to the terms of the W3C Patent Policy.

Participants in the group are required (by the W3C Process) to follow the W3C Code of Ethics and Professional Conduct.


Technical discussions for this Interest Group are conducted in public: the meeting minutes from teleconference and face-to-face meetings will be archived for public review, and technical discussions and issue tracking will be conducted in a manner that can be both read and written to by the general public. Working Drafts and Editor's Drafts of deliverables will be developed on a public repository and may permit direct public contribution requests. The meetings themselves are not open to public participation, however.

Information about the group (including details about deliverables, issues, actions, status, participants, and meetings) will be available from the Smart Cities Interest Group home page.

Most Smart City Interest Group teleconferences will focus on discussion of particular deliverables, and will be conducted on an as-needed basis.

This group primarily conducts its technical work on GitHub issues. The public is invited to review, discuss and contribute to this work.

The group may use a Member-confidential mailing list for administrative purposes and, at the discretion of the Chairs and members of the group, for member-only discussions in special cases when a participant requests such a discussion.

Decision Policy

This group will seek to make decisions through consensus and due process, per the W3C Process Document (section 3.3). Typically, an editor or other participant makes an initial proposal, which is then refined in discussion with members of the group and other reviewers, and consensus emerges with little formal voting being required.

However, if a decision is necessary for timely progress and consensus is not achieved after careful consideration of the range of views presented, the Chairs may call for a group vote and record a decision along with any objections.

To afford asynchronous decisions and organizational deliberation, any resolution (including publication decisions) taken in a face-to-face meeting or teleconference will be considered provisional. A call for consensus (CfC) will be issued for all resolutions (for example, via email, GitHub issue or web-based survey), with a response period from one week to 10 working days, depending on the chair's evaluation of the group consensus on the issue. If no objections are raised by the end of the response period, the resolution will be considered to have consensus as a resolution of the Interest Group.

All decisions made by the group should be considered resolved unless and until new information becomes available or unless reopened at the discretion of the Chairs or the Director.

This charter is written in accordance with the W3C Process Document (Section 3.4, Votes) and includes no voting procedures beyond what the Process Document requires.

Patent Disclosures

The Interest Group provides an opportunity to share perspectives on the topic addressed by this charter. W3C reminds Interest Group participants of their obligation to comply with patent disclosure obligations as set out in Section 6 of the W3C Patent Policy. While the Interest Group does not produce Recommendation-track documents, when Interest Group participants review Recommendation-track specifications from Working Groups, the patent disclosure obligations do apply. For more information about disclosure obligations for this group, please see the W3C Patent Policy Implementation.


This Interest Group will use the W3C Document license for all its deliverables.
