Vector Markup Language (VML) is an XML-based file format for two-dimensional vector graphics. VML is specified in Part 4 of the Office Open XML standards ISO/IEC 29500 and ECMA-376. According to the specification, VML should be considered a deprecated format included in Office Open XML for legacy reasons only.〔(【引用サイトリンク】title=Ecma TC45 - New proposed dispositions extend progress in addressing all National Body comments, seek to document and resolve legacy issues – Nearly 2/3 of comments now reviewed )〕 VML is pervasively used in MS Office 2007 (and later version) documents (i.e. Word, Excel and PowerPoint documents).〔〔(【引用サイトリンク】title=Microsoft Office XML formats ? Defective by design )〕 As of 2012, with the release of Internet Explorer 10, VML became obsolete and was no longer deemed supported by Microsoft.〔(【引用サイトリンク】title=VML is no longer supported )〕 VML, now considered a legacy feature remains available in Internet Explorer 10 only when the browser is set to run in modes to emulate the functionality of previous versions of Internet Explorer 6, 7, 8, and 9. == History == VML was submitted to the W3C in 1998 by Autodesk, Hewlett-Packard, Macromedia, Microsoft, and Vision. Around the same time other competing W3C submissions were received in the area of web vector graphics, such as PGML from Adobe Systems, Sun Microsystems, and others. As a result of these submissions, a new W3C working group was created, which produced Scalable Vector Graphics (SVG). SVG became a W3C Recommendation in 2001 as a language for describing two-dimensional vector and mixed vector/raster graphics in XML. VML has been largely deprecated in favor of other formats, such as SVG. SVG is not compatible with VML.〔(【引用サイトリンク】title=VML — Vector Graphics on the Internet )〕 Development of the format ceased in 1998. VML is implemented in Internet Explorer from version 5 to version 9 and in Microsoft Office 2000. VML is no longer available in Internet Explorer 10. Microsoft expects web sites to transition to SVG. Version 2 of the Google Maps JavaScript API used to use VML for vector paths on Internet Explorer 5.5+, but has been officially deprecated in favour of version 3, which does not. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vector Markup Language」の詳細全文を読む スポンサード リンク
