构建信息传播网络的NPC框架
The NPC Framework for Building Information Dissemination Networks
摘要：
过去已经开发了许多用于文件的传播、检索和存档的系统。这些系统通常集中在这些方面之一，很难扩展和组合。通常，传输协议、查询和过滤语言以及与其他系统的接口都是固定的。相反，我们设想在信息提供者、储存库和消费者之间建立无缝网络，支持信息检索和传播，同时具有高度的互操作性和可扩展性。我们提出了一个框架，一个单一的基于事件的机制，统一的文档存储，检索和传播。该框架提供了文档和元数据格式、传输协议和过滤机制方面的完全开放性。它指定了一个高层次的构建工具包，通过该工具包，可以将任意的文档流处理器合并到一起，以支持文档的检索、转换、聚合和分解。使用相同的套件，可以容易地添加用于不同传输协议的接口，以实现与各种信息源和信息消费者的通信。
英文摘要：
Numerous systems for dissemination, retrieval, and archiving of documents have been developed in the past. Those systems often focus on one of these aspects and are hard to extend and combine. Typically, the transmission protocols, query and filtering languages are fixed as well as the interfaces to other systems. We rather envisage the seamless establishment of networks among the providers, repositories and consumers of information, supporting information retrieval and dissemination while being highly interoperable and extensible. We propose a framework with a single event-based mechanism that unifies document storage, retrieval, and dissemination. This framework offers complete openness with respect to document and metadata formats, transmission protocols, and filtering mechanisms. It specifies a high-level building kit, by which arbitrary processors for document streams can be incorporated to support the retrieval, transformation, aggregation and disaggregation of documents. Using the same kit, interfaces for different transmission protocols can be added easily to enable the communication with various information sources and information consumers.
