Abstract This specification defines the features and syntax for ScalableVector Graphics (SVG) Version 2. SVG is a language based on XML for describingtwo-dimensional vector and mixed vector/raster graphics. SVG content is stylable,scalable to different display resolutions, and can be viewed stand-alone,mixed with HTML content, or embedded using XML namespaces within other XML languages.SVG also supports dynamic changes; script can be used to create interactive documents,and animations can be performed using declarative animation features or by using script.
Status of This Document This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in theW3C technical reports index at https://www.w3.org/TR/.
This document is the 04 October 2018Candidate Recommendation of SVG 2. This version of SVG builds uponSVG 1.1 Second Edition by improving the usability and precision of the language. TheChanges appendix lists all of the changes that have been made since SVG 1.1 Second Edition.
Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 04 December 2018.
There is no preliminary implementation report at this time. The SVG Working Group is working on a test suite for SVG2 and expects to produce an implementation report based on those tests.
Comments on this Candidate Recommendation are welcome. Comments can be raised asGitHub issues (preferred), or alternatively be sent towww-svg@w3.org , the public email list for issues related to vector graphics on the Web. This list isarchived and senders must agree to have their message publicly archived from their first posting. To subscribe send an email towww-svg-request@w3.org with the wordsubscribe in the subject line.
The specification includes a number of annotations that the Working Group is using to record links to meeting minutes and resolutions where specific decisions about SVG features have been made. Different coloring is also used to mark the maturity of different sections of the specification:
a red background indicates a section that is either unchanged since SVG 1.1 (and which therefore still requires review and possible rewriting for SVG 2), or a section that is new but still requires substantial work a yellow background indicates a section from SVG 1.1 that has been reviewed and rewritten if necessary, or a new section that is complete and ready for the rest of the Working Group to review a white background indicates a section, either from SVG 1.1 or new for SVG 2, that has been reviewed by the Working Group and which is ready for wider review This document has been produced by theW3C SVG Working Group as part oftheGraphics Activity withintheW3C Interaction Domain . Thegoals of the W3C SVG Working Group are discussed in theW3C SVG Charter .The W3C SVG Working Group maintains a public Web page,https://www.w3.org/Graphics/SVG/ ,that contains further background information. The authors ofthis document are the SVG Working Group participants.
This document was produced by a group operating under theW3C Patent Policy . W3C maintains apublic list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent. An individual who has actual knowledge of a patent which the individual believes containsEssential Claim(s) must disclose the information in accordance withsection 6 of the W3C Patent Policy .
A list of current W3C Recommendations and other technical documents can be found athttps://www.w3.org/TR/ . W3C publications may be updated, replaced, or obsoleted by other documents at any time.
This document is governed by the1 February 2018 W3C Process Document .
All features in this specification depend upon implementation in browsersor authoring tools. If a feature is not certain to be implemented, we definethat feature as "at risk". At-risk features will be removed from the currentspecification, and may be included in future versions of the specification. Ifan at-risk feature is particularly important to authors of SVG, those authorsare encouraged to give feedback to implementers regarding its priority. Thefollowing features are at risk, and may be dropped during the CR period:

In addition, the SVG Working Group would like to acknowledge thecontributions of the editors and authors of the previous versionsof SVG – as much of the text in this document derives from theseearlier specifications – including:
Patrick Dengler, Microsoft Corporation(Version 1.1 Second Edition) Jon Ferraiolo, ex Adobe Systems(Versions 1.0 and 1.1 First Edition; until 10 May 2006) Anthony Grasso, ex Canon Inc.(Version 1.1 Second Edition) Dean Jackson, ex W3C(Version 1.1 First Edition; until February 2007) 藤沢 淳 (FUJISAWA Jun), Canon Inc.(Version 1.1 First Edition) Finally, the SVG Working Group would like to acknowledge thegreat many people outside of the SVG Working Group who help with theprocess of developing the SVG specifications. These people are toonumerous to list individually. They include but are not limited tothe early implementers of the SVG 1.0 and 1.1 languages (includingviewers, authoring tools, and server-side transcoders), developers ofSVG content, people who have contributed on thewww-svg@w3.org andsvg-developers@yahoogroups.com email lists, other Working Groups at theW3C, and the W3C Team. SVG 1.1 is truly a cooperative effort betweenthe SVG Working Group, the rest of the W3C, and the public and benefitsgreatly from the pioneering work of early implementers and contentdevelopers, feedback from the public, and help from the W3C team.
