I’d like to inform about Web Applications performing Group Charter

The objective for the internet Applications performing Group (Web WG) is always to create requirements that facilitate the growth of client-side web applications.

Start date 14 May 2019
End date 31 May 2021
Chairs LГ©onie Watson (TetraLogical), Marcos CГЎceres (Mozilla)
Team Contacts Xiaoqian Wu (0.1 FTE )
Meeting Schedule Teleconferences: topic-specific telephone calls are going to be held whenever required. Face-to-face: we shall fulfill through the W3C’s yearly Technical Plenary week; extra meetings that are face-to-face be planned by permission of individuals.


The range associated with online performing Group is:

  • Haptic input devices and their emitted activities and/or information.
  • Textual input and text manipulation.
  • Information sharing across remote and web that is local.
  • Acting and receiving upon information from remote sources.
  • Accessing the file system and storage that is persistent.
  • Interfacing with OS abilities.
  • Integrating internet applications utilizing the OS.

The working group additionally keeps a specification for mapping HTML elements and attributes to platform accessibility APIs, and a separate specification that describes writer conformance demands for establishing ARIA characteristics. The performing Group will not expect you’ll add some other requirements concerning this matter.

Requirements generated by the internet Working Group allow developers to create internet applications that really work across an extensive selection of platforms and products, as well as for a diverse variety of users, by handling issues of accessibility, unit liberty, internationalization, privacy, and protection.

Success Criteria

Each specification must have at least two independent implementations in wide use in order to advance to Proposed Recommendation.

Each specification will need to have an accompanying test suite, that is ideally developed in parallel into the specification. The test suite shall be employed to create an execution report prior to the specification lusty-locals giriЕџ transitions to Proposed Recommendation.

Where you can find implications for implementors, designers, or users, when you look at the regions of accessibility, internationalization, privacy, and protection, each specification should have a area that defines appropriate benefits, limits, and practice solutions that are best for the specific area.


More details about online performing Group specs are available in the GitHub repository.

Normative Requirements

The net Working Group will provide the after normative specs.

Degree 1 associated with API that represents gamepad products, and enables internet applications to do something upon gamepad data.

Degree 2 is designed to offer the abilities of next generation gamepads.

Improvements to occasions for text and input that is related provide for the monitoring and manipulation of standard web browser behavior within the context of text editor applications as well as other applications that handle text input and text formatting. Degree 1 provides the JS editor information regarding proposed modifications through the user, however it helps make the associated DOM change be non-cancelable quite often.

Degree 2 provides the JS editor information details about the proposed modifications through the user and allows the JS author cancel the modifications the web browser otherwise will have done.

Specification explanation
File API An API for representing file things in internet applications, in addition to programmatically picking them and accessing their information.
Gamepad API
Indexed Database API An API for a database of records keeping easy values and objects that are hierarchical. The 3rd version adds brand new abilities and improves developer ergonomics by making use of claims.
Intersection Observer An API which can be used to comprehend the presence and place of DOM elements (“targets”) relative to an element that is containing into the top-level viewport (“root”).
Pointer Lock An API providing you with scripted usage of natural mouse movement data while locking the goal of mouse activities to an individual element and getting rid of the cursor from view.
drive API An API for giving push communications to a internet application, via a push solution.
Screen Orientation API An API for reading display screen orientation, being informed of display orientation changes, and securing display screen orientation up to a particular state.
online App Manifest A JSON-based manifest file that delivers developers having a central location to place metadata connected with an internet application.
Clipboard API and Events An API for accessing information from the operational system clipboard.
Input Occasions
Selection API APIs for selection, which enable users and writers to pick a percentage of a document or specify a true point of great interest for content, paste, along with other modifying operations.
ContentEditable granted values and anticipated actions for the attribute that is contenteditable.
HTML Accessibility API Mappings (AAM) Defines exactly exactly how user agents map HTML elements and attributes to platform accessibility APIs.
ARIA in HTML Defines the net designer guidelines (author conformance demands) for ARIA features on HTML elements.
UI Events UI occasions that increase the DOM Event objects defined when you look at the DOM specification.
UI Events KeyboardEvent code values The values for the KeyboardEvent.code feature, which will be understood to be an element of the UI Events Specification.
UI Events KeyboardEvent key Values The values for the attribute that is key in the UI Activities specification.

WICG specs

With respect to the WICG progress, the Group might also produce W3C tips for the documents that are following

Specification explanation
Cookie shop An asynchronous Javascript snacks API for papers and employees.
internet Share API An API for sharing text, links along with other content to an arbitrary location for the individual’s option.
internet Share Target An API which allows web sites to declare on their own as internet share objectives, which could get provided content from either the Web Share API, or system occasions ( ag e.g., stocks from indigenous ).
Badging An API permitting web applications to create an application-wide badge, shown in a operating-system-specific spot from the application (for instance the rack or house display screen), for the intended purpose of notifying the consumer once the state of this application has changed ( e.g., when brand brand new communications have actually appeared), without showing an even more heavyweight notification.
