The image above shows the Amaya main view. Along the top are a number of buttons associated with browsing. The panel at the left proposes a set of editing tools. At any time, the user can select any part of a document and assign to it an HTML type (H1, LI, EM, etc.), by means of the XHTML palette, or of the shortcut buttons. Such a command transforms the selected part into an element of the chosen type. Transport protocols Amaya accesses remote sites by means of HTTP/1.1. Implementation of this protocol is provided by the W3C libwww. Amaya takes advantage of the most advanced features of HTTP, such as content negotiation to retrieve the most appropriate picture format, keep alive connections to save bandwidth and authentication to allow secure remote publishing. Support for CSS Amaya has support for the W3C style sheet language CSS although this is not yet complete. For simple properties like foreground color, background color, background image, alignment, etc. the user can interact on the formatted document by using style menus or a set of specific tools. In this case it's not necessary to know about the CSS syntax. At the same time Amaya provides an efficient mechanism to test and associate external style sheets with HTML documents. Users can also use Amaya to download, edit and publish CSS style sheets as well as HTML pages. Support for MathML Amaya demonstrates an implementation of MathML which allows users to browse and edit Web pages containing mathematical expressions (see some examples). Like the rest of the document, these expressions are manipulated through a WYSIWYG interface. Amaya uses namespaces to integrate MathML expressions within XHTML documents, i.e. HTML documents written in XML syntax. This mechanism is also used to mix graphics in SVG and mathematics in MathML within XHTML documents (see an example). This screen shot is a demonstration of MathML, an XML application resulting from work by the W3C Math working group. MathML allows authors to format equations for publishing on the World Wide Web. With Amaya, an author can see the formatted view and the structure view at the same time. Support for SVG Amaya displays images including those in the PNG format, which is a more powerful graphics format than GIF and is being increasingly used on the Web. Amaya supports also a subset of the Scalable Vector Graphics (SVG) format, namely basic shapes, text, images, and foreignObject (the latter is useful to include HTML fragments or MathML expressions in drawings). The graphics are written in XML and may be mixed freely with HTML and MathML. Support for RDF and XPointer Amaya includes a collaborative annotation application based on Resource Description Framework (RDF), XLink, and XPointer. From the technical point of view, annotations are usually seen as metadata, as they give additional information about an existing piece of data. In this project, we use a special RDF annotation schema for describing annotations. Annotations can be stored locally or in one or more annotation servers. When a document is browsed, Amaya queries each of these servers, requesting the annotations related to that document.. Amaya uses XPointer to describe where an annotation should be attached to a document. With this technique, it is possible to annotate any Web document independently, without needing to edit that document. Finally Amaya presents annotations with pencil annotation icons . and attaches XLink attributes to these icons. If the user single-clicks on an annotation icon, the text that was annotated is highlighted. If the user double-clicks on this icon, the annotation text and other metadata are presented in a separate window. Printing Amaya offers some facilities like printing the table of contents of the document. the table of links, the URI of the document. Amaya 9.0 以後徹底改寫，以下是嶄新的功能列表： . new User Interface . HTML 4.01 .
