摘要:
A client/server system for authoring an on-line service uses a server machine accessed a client machine which performs authoring operations on information stored on the server machine comprising the on-line service. Requests for authoring operations to be performed on information on the server machine, for authoring the online service, are translated on the client machine into at least one message which is sent to the server machine. The server machine receives the at least one message from the client machine and performs authoring operations identified in the received at least one message so as to author the online service. This information on the server machine is then made accessible by the server machine to other client systems that can be used to access the information without modifying the information, such as a browser. Generally, when the client machine receives a response message from the server machine, it displays information about performance of the authoring operation by the server, using the response message. The client and server may communicate using the HTTP protocol over a TCP/IP connection. The may also have different file name spaces, requiring the server to maintain and perform mapping between identifiers used by the client and those used on the server. The server may have a server program for processing HTTP messages and a server extension program for processing authoring operations. This extension program can be called via the common gateway interface. The authoring operations to be performed can include storing, creating or modifying information, such as documents and scripts and meta-information about services, documents and scripts on the server. Also, operations for providing a listing of services and documents are also available.

A client/server computer system for remote editing of document objects stored on the server includes a client computer connected to a server computer via a communication channel over which messages are sent in a communication protocol. Typically, the client computer has an operating system with a first file name space and the server computer has an operating system with a second file name space and the first file name space does not include names of files which map to names of files in the second file name space. The connection is preferably a TCP/IP connection providing data transport according to TCP/IP. Messages in the HTTP protocol are preferably used. The client computer sends request messages to the server. A request message may indicate a request for either retrieval or storage of a document object, such as an HTML document or script program. The server receives the request messages and processes them to either store a document object or retrieve a document object and return it to the client in a response message. When the server is an HTTP server, the request messages from the client are processed by a single control script. The messages from the client indicate a desired document object and the action to be performed.

Techniques for managing a playlist in a multimedia system are disclosed. According to one aspect of the techniques, the playlist is structured to be able to include as many items as desired. To facilitate the manageability of such playlist, the playlist is built with a plurality of items. Each of the items is associated with metadata that includes information related to, for example, artist, album, genre, composer, and track number. The metadata for each item may be parsed, updated or logically operated upon to facilitate the management of the playlist. In another embodiment, each of the items is either a single item or a group item. A single item contains metadata of a corresponding source. A group item contains metadata of accessing other constituent items, which again may be single items or group items. As a result, the playlist can accommodate as many items as desired in a limited memory space without compromising the manageability of the playlist. Each of the items can be removed from, added to, or moved around in the playlist without concerning that an item may further include many items therein.

A token identifies a special comment that includes information usable by a specific Web page editor. Tile information included within a special comment may include authoring state information, such as parameters used by "WEBBOT" components to provide extensions to hypertext markup language (HTML) features. When a Web page is opened, the editor parses each element on the page and determines if a comment is special by detecting the presence of a predefined token. In the preferred embodiment, the token is the word "WEBBOT." The information included within this special comment can include references to extensions to HTML tags, including those that are not known by the editor, and parameters required by HTML extensions. Since the special comment is in a format ignored by Web browsers, it does not impact upon the ability of a browser to render the page.

Techniques pertaining to efficient scrolling a list are disclosed. One of the features of the efficient scrolling is to provide a graphic user interface that displays items in the list so that a user may scroll the list using a scroll wheel. After an item is highlighted for a predefined time, an information panel is automatically displayed to show hidden information associated with the item. The information panel is superimposed in an area of the graphic user interface, without obstructing the highlighted item.
