Introduction Scalable Vector Graphics (SVG) is a standard that defines vector- based graphics for the web, graphics that can be expressed in XML format. SVG is an extensible format, with support for various metadata elements and animation. In some cases, it is preferable to have an SVG profile that is targeted at smaller platforms, and/or to have security in mind. This document defines a profile of SVG for such use cases, called the SVG Tiny PS profile, that limits the allowed elements to a subset of the features supported by the overall SVG specification. The SVG standard is defined by the World Wide Web Consortium (W3C) and the current version is 1.1 [SVG]. The W3C also defines a simplified profile of SVG published as SVG Tiny [SVGT], with the current version at 1.2. This document defines the SVG Tiny PS profile in the terms of the simplified SVG Tiny 1.2 as the base. The SVG Tiny PS profile identifies elements that are required, disallowed, or otherwise allowed from the set of elements defined by SVG Tiny 1.2. No elements are added to SVG Tiny PS, and any elements not explicitly mentioned in this document follow the guidance provided by SVG Tiny 1.2. Brotman & Adams Expires 14 April 2022 [Page 2] RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS October 2021 2. SVG Tiny PS Profile This document defines the SVG Tiny PS profile in the terms of the simplified SVG Tiny 1.2 as the base. The following sections reference sections within the SVG Tiny PS profile that are required, disallowed, or otherwise allowed from the set of elements defined by SVG Tiny 1.2. No elements are added to SVG Tiny PS that are not found within SVG 1.1 or SVG Tiny 1.2, and any elements not explicitly mentioned in this document follow the guidance provided by SVG Tiny 1.2. 2.1. Specific Instructions for the SVG Tiny PS Documents The elements and attributes below are required within the root element of an SVG Tiny PS document. * Document Definition: The SVG Tiny PS document MUST be defined as described in SVG Tiny 1.2 Section 1.3. This includes setting the following attributes as follows: xmlns="http://www.w3.org/2000/svg" version="1.2" baseProfile="tiny-ps" [ Note to WG: Based on other baseProfile, this should be the minimum profile required to render the image. Tiny PS should be a subset, but we're unsure if we should create a smaller profile. ] * title: The element MUST be present and its contents MUST NOT be empty. The title element MUST occur only once as a sub- element of the svg element. The contents SHOULD be no more 64 characters. * desc: The element MAY be present with a longer description. If present, its contents MUST NOT be empty, and care SHOULD be given to minimize the file size of the document. 2.2. Permitted Sections with Restrictions The following sections from SVG Tiny 1.2 MAY be used within an SVG Tiny PS document with the further restrictions as noted. * Section 8: Paths - This section defines methods used for defining vector-based paths that can be rendered. The attributes "d" and "pathLength" MUST NOT be animated. The elements described within "8.2.1 Animating path data" MUST NOT be present within an SVG Tiny PS document. Brotman & Adams Expires 14 April 2022 [Page 3] RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS October 2021 * Section 9: Basic Shapes - This section defines primitives that can be used to render basic shapes. The attributes "x", "y", "width", "height", "rx", and "ry" MUST NOT be animated. * Section 10: Text - This sections describes the methods for defining text that should be rendered similar to any vector-based graphic elements. The "editable" attribute SHOULD NOT be present in an SVG Tiny PS document, if it is, it MUST be set to "none". The attributes "x", "y", and "rotate" MUST NOT be animated. * Section 11: Painting - This section describes the methods used to render the paths ("stroked") and shapes ("filled") visible. Any of the attributes described MUST NOT be animated within an SVG Tiny PS document. 2.3. Disallowed Sections, Elements, and Attributes The elements and attributes described in the sections below MUST NOT be present in an SVG Tiny PS document: * Section 5.7: The 'image' Element - This section defines methods for displaying a raster image within the context of an SVG image. * Section 5.8.2: The 'switch' Element - This section defines methods for conditional processing of the document. * Section 12: Multimedia - This section describes the elements that augment an image with audio or video. * Section 13: Interactivity - This section describes elements related to user actions and responsiveness to those events. * Section 14: Linking - This section describes links to internal and external end points. * Section 15: Scripting - This section describes methods for adding executable content. * Section 16: Animation - This section describes methods for transforming or otherwise animating elements over time. The attributes below are specifically called out from the sections above due to their widespread use. For a more complete list, refer to the full content in the sections above. * zoomAndPan: The "zoomAndPan" attribute SHOULD NOT be present in an SVG Tiny PS document. If it is present, it MUST be set to "disable". Brotman & Adams Expires 14 April 2022 [Page 4] RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS October 2021 * externalResourcesRequired: The "externalResourcesRequired" attribute SHOULD NOT be present in an SVG Tiny PS document. If it is present, it MUST be set to "false". * focusable: The "focusable" attribute SHOULD NOT be used within an SVG Tiny PS document. If it is present, it MUST be set to "false". * snapshotTime: The "snapshotTime" attribute SHOULD NOT be used within an SVG Tiny PS document. If it is present, it MUST be set to "none". * playbackOrder: The "playbackOrder" attribute SHOULD NOT be used within an SVG Tiny PS document. If it is present, it MUST be set to "all". * timelineBegin: The "timelineBegin" attribute SHOULD NOT be used within an SVG Tiny PS document. If it is present, it MUST be set to "onLoad". 2.4. Additional Considerations for Creating SVG Tiny PS Documents The following are special considerations that SHOULD be taken when creating an SVG Tiny PS document: * The file size of SVG Tiny PS documents SHOULD be as small as possible, and SHOULD NOT exceed 32 kilobytes. That size should be evaluated when the document is uncompressed. * An SVG Tiny PS document MUST include at least two colors when rendered. * Section 17: Fonts - This sections describes the methods for defining specific characters to be used within an SVG document. Embedded character definitions MAY be used in an SVG Tiny PS document, but the document SHOULD only include the characters to be rendered, and SHOULD NOT include any additional characters that are not to be rendered. * Section 18: Metadata - This section summarizes standard methods for including structured data about the content within an SVG document. While metadata can support utility and accessibility and MAY be included in an SVG Tiny PS document, careful consideration SHOULD be given to how the metadata element and extensible metadata attributes are used to avoid increasing the file size of the document. Brotman & Adams Expires 14 April 2022 [Page 5] RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS October 2021 * An SVG Tiny PS document MAY include transparent elements, however care SHOULD be taken to understand the implications of transparency when rendered. Given that the author has no control over how the logo is ultimately displayed, transparency to the underlying display mechanism could result in undesirable effects. 3. Security Considerations Many of the requirements imposed by the SVG Tiny PS profile are designed to minimize potential security concerns introduced by interactive content into a user experience not typically designed to handle it. Every consideration has been made to reduce the scope of SVG images to the minimum elements necessary to render locally defined, static vector graphics. 3.1. Portability The SVG documents meant to be used with this profile should be fairly portable, and should likely be self-contained. The document authors cannot be certain that the client will have an active network connection. 4. Contributors TBD 5. Example SVG Tiny PS Document Example, Inc. Logo for Example, Inc. 6.
