    • Disclosed is software architecture and method for sharing data objects among multiple applications in a client device. The architecture includes a server process in the client device for processing a template, such as a SHTML template for the Extended Markup Language (XML), based on a template identifier value received from a user application. Each of multiple applications has a template. Each template identifies a series of objects identified by tag values, such as XML entities, that are to be incorporated into a display page. A database of objects, such as a database of XML entities identified by tag values, is maintained that contains data objects for the applications. An update process periodically establishes a communication link with a remote server and requests download of a data document containing content data corresponding to at least a portion of several of the templates. The data document is parsed into the database of objects based on the structure of the data document, which generally conforms to a data type definition. When the server process processes different templates that reference the same data object, it will retrieve the data object from the database. Each template may then be rendered into a page of output data for display to a user. The architecture and method according to the present invention thus permit data objects to be shared by multiple applications and to be automatically updated. Each time a data object is updated, the data will be current for each user application that references the data object.
    • 公开了用于在客户端设备中的多个应用之间共享数据对象的软件架构和方法。 基于从用户应用程序接收的模板标识符值,该架构包括用于处理模板的客户端设备中的服务器进程,例如用于扩展标记语言(XML)的SHTML模板。 每个应用程序都有一个模板。 每个模板都标识一系列由标签值标识的对象,例如XML实体,这些对象将被并入到显示页面中。 对象的数据库(例如由标签值标识的XML实体的数据库)进行维护,其中包含应用程序的数据对象。 更新过程周期性地建立与远程服务器的通信链路,并请求下载包含对应于几个模板的至少一部分的内容数据的数据文档。 基于数据文档的结构,将数据文档解析成对象的数据库,这通常符合数据类型定义。 当服务器进程处理引用同一数据对象的不同模板时,它将从数据库中检索数据对象。 然后可以将每个模板呈现为输出数据的页面以供用户显示。 因此,根据本发明的架构和方法允许数据对象由多个应用共享并被自动更新。 每次更新数据对象时,数据将是引用数据对象的每个用户应用程序的当前数据。
