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

The objective for the online Applications performing Group (Web WG) is always to create requirements that facilitate the growth of client-side internet 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 phone calls may be held when required. Face-to-face: we are going to satisfy throughout the W3C’s annual Technical Plenary week; extra face-to-face conferences may be planned by permission of individuals.


The range for the internet Working Group is:

  • Haptic input devices and their emitted occasions and/or data.
  • Textual text and input manipulation.
  • Data sharing across remote and neighborhood internet applications.
  • Getting and acting upon information from remote sources.
  • Accessing the file system and persistent storage space.
  • Interfacing with OS abilities.
  • Integrating web applications because of the OS.

The working group additionally keeps a specification for mapping HTML elements and attributes to platform accessibility APIs, and a split specification that describes writer conformance demands for establishing ARIA attributes. The performing Group doesn’t be prepared to include some other specs with this matter.

Specs made by the Web Working Group help developers to generate internet applications that really work across a broad array of platforms and products, as well as for an extensive variety of users, by handling things of accessibility, unit self-reliance, internationalization, privacy, and protection.

Success Criteria

So that you can advance to Proposed Recommendation, each specification will need to have at the very least two separate implementations in wide usage.

Each specification will need to have a test that is accompanying, which will be preferably developed in parallel into the specification. The test suite will be employed to create an execution report ahead of the specification transitions to Proposed Recommendation.

Where you can find implications for implementors, designers, or users, within the regions of accessibility, internationalization, privacy, and safety, each specification should have an area that defines appropriate advantages, restrictions, and practice solutions that are best for that specific area.


More details about internet performing Group requirements are available in the GitHub repository.

Normative Specs

The net performing Group will provide the after normative specs.

Amount 1 associated with the API that represents gamepad products, and enables internet applications to do something upon gamepad information.

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

Improvements to occasions for text and relevant input to provide for the monitoring and manipulation of standard web browser behavior when you look at the context of text editor applications as well as other applications that handle text input and text formatting. Degree 1 provides the JS editor details about proposed changes through the individual, nonetheless it helps make the relevant DOM change be non-cancelable quite often.

Degree 2 provides the JS editor information information regarding the proposed modifications through the individual and lets the JS author cancel the noticeable modifications the web browser otherwise might have done.

Specification definition
File API An API for representing objects that are file internet applications, in addition to programmatically choosing them and accessing their information.
Gamepad API
Indexed Database API An API for the database of documents keeping easy values and objects that are hierarchical. The edition that is third brand brand new abilities and improves designer ergonomics by making use of claims.
Intersection Observer An API which can be used to know the exposure and position of DOM elements («targets») general to an element that is containing towards the top-level viewport («root»).
Pointer Lock An API providing you with scripted use of natural mouse movement information while securing the mark of mouse occasions to an individual element and getting rid of the cursor from view.
drive API An API for giving push communications to an internet application, with a push solution.
Screen Orientation API An API for reading display orientation, being informed of display orientation changes, and securing display orientation to a state that is specific.
internet App Manifest A JSON-based manifest file providing you with designers by having a central location to put metadata connected with an internet application.
Clipboard API and Events An API for accessing information in the 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, as well as other modifying operations.
ContentEditable granted values and anticipated habits for the contenteditable attribute.
HTML Accessibility API Mappings (AAM) Defines exactly how user agents map HTML elements and attributes to platform accessibility APIs.
ARIA in HTML Defines the net designer guidelines (writer conformance demands) for ARIA features on HTML elements.
UI Events UI Activities that extend the DOM Event objects defined within the DOM specification.
UI Events KeyboardEvent code values The values for the KeyboardEvent.code feature, that will be thought as area of the UI Events Specification.
UI Events KeyboardEvent key Values The values for the key characteristic defined when you look at the UI Activities specification.

WICG specs

With regards to the WICG progress, the Group could also create W3C strategies for the documents that are following

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