SCIENTIFIC VISUALIZATION USING W3C STANDARDS

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 网络的出现对科学实践产生了重大而持久的影响。 数据，结果，程序和科学信息可以下载，或以文本形式查看静态图像。 要在Web上交互式地查看图形数据，需要特殊的插件技术或Java applet，这增加了访问的复杂性和障碍。 W3C最近的标准活动承诺通过一种类似于HTML的丰富的声明性图形语言（称为可缩放矢量图形（SVG））来改善这些障碍。 SVG已经广泛地在图形软件包中实现，如Photoshop，Illustrator，但是如果不添加插件，则无法通过Web浏览器使用。 通过与开源Web浏览器开发社区的合作，我们正在扩展基于Mozilla的浏览器的功能（例如，Firefox、Mozilla），以支持使用SVG来实现图形数据的可视化。 随着SVG作为Firefox的本地组件发布，HTML中的文本和图像将能够与通过SVG描述的可缩放矢量图形混合。 这将用于加强获得由RBVI提供的科学资源和信息。 例如，我们计划实现一个色谱图查看器，用于直接在Web浏览器中显示DNA序列的“痕迹”。 这将直接惠及RBVI内的两个合作项目，即膜转运蛋白药物遗传学（PMT）和BayGenomics，并且对一般DNA测序界非常有用。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The advent of the web has had a significant and lasting impact on the practice of Science. Data, results, procedures, and scientific information can be downloaded, or viewed as text with static images. To view graphical data interactively on the web has required special plug-in technologies or Java applets which increase the complexity and hurdles to access. Recent standards activities by the W3C promise to ameliorate these hurdles through a rich declarative graphical language similar to HTML called Scalable Vector Graphics (SVG). SVG is already widely implemented in graphics packages such as Visio, Photoshop, and Illustrator, but has not been available through a web browser without the addition of a plug-in. Through collaboration with the open-source web-browser development community, we are extending the functionality of the Mozilla-based browsers (e.g., Firefox, Mozilla) to support the use of SVG for visualization of graphical data. With the release of SVG as a native component of Firefox, text and images within HTML will be able to be mixed with scalable vector graphics described via SVG. This will be used to enhance the access to scientific resources and information provided by RBVI. For example, we plan to implement a chromatogram viewer for the display of DNA sequence "traces" directly within a web-browser. This will directly benefit two collaborative projects within the RBVI, the Pharmacogenetics of Membrane Transporters (PMT) and BayGenomics, as well as be very useful to the general DNA sequencing community.
