摘要： Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative session. One or more controllers connect the users or collaborators in a session in the server system. This is realized by establishing a so-called “shared Web-top”, i.e., a work space, in which different in-document applications can be run and can be interactively, collaboratively shared by a plurality of users. Specifically, this is realized by employing a surrogate that includes a polling loop which periodically checks a shared document structure for changes in prescribed properties, and transmits the detected changes to surrogates of other users, i.e., at least one other collaborator, via a communication channel. To this end, a prospective user of the shared Web-top accesses a system, which transmits mobile code to the user's computer to create a surrogate thereon. The surrogates created for the users of the shared Web-top are connected by at least one controller in the system and individually serve as an interface between the controller and the respective browsers on the users computers. Advantageously, through our unique use of the polling loop in the surrogate, functionality is realized in which, as one user inputs data into a shared document, for example, into one or more forms in a document, the same data appears in the other user's browser, via the detected changes in prescribed properties of the one or more forms being transmitted over the communication channel to the users' computers and, therein, to their surrogates.

摘要： Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. One or more controllers connect the users or collaborators in a session in the server system. This is realized by establishing a so-called “shared Web-top”, i.e., a work space, in which different in-document applications can be run and can be interactively, collaboratively shared by a plurality of users. Specifically, this is realized in one embodiment by employing event handlers in the WEB documents that are activated whenever there is a change in the values of prescribed properties of a document. The event handlers notify a so-called surrogate of the changes in the prescribed properties of the document, i.e., that values in elements of a form have changed, and transmit the detected changes to surrogates of other users, i.e., at least one other collaborator, via a communication channel. To this end, a prospective user of the shared Web-top accesses a system that transmits mobile code to the user's computer to create a surrogate thereon. The surrogates created for the users of the shared Web-top are connected by at least one controller in the system and individually serve as an interface between the controller and the respective browsers on the users computers. Alternatively, the surrogate can insert event handlers into the document that communicate with the surrogate, identifying which form elements they apply to and transmit the changed value(s) to other users. The surrogates of the other users then appropriately update the corresponding form elements to reflect the changes.

摘要： An arrangement for realizing asymmetric collaboration utilizes a “shared Web-top”, i.e., a work space, in which different in-document applications can run and be shared. Specifically, in one embodiment of the invention employed in asymmetric collaboration, documents to be collaborated on at different users' terminals are logically identical but structurally different. Indeed, one of the collaborators, for example, a customer service agent, may have access to information that should not be made available to others of the collaborators. This asymmetric collaboration is realized by assigning a unique logical name to each information entity. Then, changes in the entity captured by some detection technique, for example, the use of document polling or event handlers, are propagated along with the name of the entity to the collaborators, where they are processed only if the relevant named entity exists. If the entity exists the logical name of the entity is mapped into its physical name which, therefore, allows asymmetric collaboration. Consequently, the name-based technique allows the collaborators, e.g., customer and agent, to share changes in the logically common portions of documents, which are structurally different.
摘要翻译：用于实现不对称协作的安排利用了可以运行和共享不同文档内应用的“共享Web-top”，即工作空间。具体来说，在不对称协作中使用的本发明的一个实施例中，要在不同用户终端上协作的文档在逻辑上是相同的，但在结构上是不同的。事实上，其中一个合作者，例如客户服务代理商，可以访问不应该向合作者的其他人提供的信息。这种不对称协作通过为每个信息实体分配唯一的逻辑名来实现。然后，通过某种检测技术捕获的实体的变化，例如使用文档轮询或事件处理程序，将与实体的名称一起传播到协作者，只有当相关的命名实体存在时才进行处理。如果实体存在，则实体的逻辑名映射到其物理名称，因此允许非对称协作。因此，基于名称的技术允许协作者，例如客户和代理人共享在结构上不同的文档的逻辑上共同部分的变化。
