Web browsers provide a user-friendly means of navigating the web. Users rely on their web browser to provide information about the websites they are visiting, such as the security state. Browsers also provide a user interface (UI) with visual cues about each tab that is open, including icons for if the tab is playing audio or requires authentication to view. However, current browsers do not differentiate between the live web and the past web. If a user loads an archived webpage, known as a memento, they have to rely on UI elements present within the page itself to inform them that the page they are viewing is not the live web. Additionally, memento-awareness extends beyond recognizing a page that has already been archived. The browser should give users the ability to archive live webpages, essentially creating mementos of webpages they found important as they surf the web. In this report, the process to create a proof-of-concept browser that is aware of mementos is presented. The browser is created by adding on to the implementation of the open source web browser by Google, Chromium. Creating this prototype for a Memento-aware Browser shows that the features implemented fit well into the current Chromium implementation. The user experience is enhanced by adding the memento-awareness, and the changes to the Chromium code base are minimal.

基于Chromium的Memento感知Web浏览器

Web浏览器提供了一种方便用户浏览Web的方法。用户依靠他们的Web浏览器来提供有关他们正在访问的网站的信息，例如安全状态。浏览器还为用户界面（UI）提供了有关打开的每个选项卡的视觉提示，包括用于显示该选项卡是否正在播放音频或需要进行身份验证才能查看的图标。但是，当前的浏览器无法区分实时网络和过去的网络。如果用户加载已存档的网页（称为备忘录），则他们必须依靠页面本身内的UI元素来告知他们正在查看的页面不是实时网络。此外，记忆感知的范围不仅仅在于识别已经存档的页面。浏览器应使用户能够存档实时网页，本质上创造了他们在浏览网页时发现重要的网页的纪念品。在此报告中，介绍了创建了解纪念品的概念验证浏览器的过程。该浏览器是通过将Google Chromium添加到开源Web浏览器的实现中来创建的。为支持Memento的浏览器创建此原型，表明所实现的功能非常适合当前的Chromium实现。通过添加记忆感知，可以增强用户体验，并且对Chromium代码库的更改很小。为具有Memento意识的浏览器创建此原型表明，所实现的功能非常适合当前的Chromium实现。通过添加记忆感知，可以增强用户体验，并且对Chromium代码库的更改很小。为支持Memento的浏览器创建此原型，表明所实现的功能非常适合当前的Chromium实现。通过添加记忆感知，可以增强用户体验，并且对Chromium代码库的更改很小。
