The paper proposes an architecture named Loglo for information integration. Building on SOA, Loglo integrates the heterogeneous information based on the descriptor loosely. Core roles in Loglo are the information provider, the information requestor and the information registry. The information provider is a web service that integrates and offers the information upon the request from the information requestor. The information registry consisting of several local registries and a global registry holds the meta-information of all public information. The local registry locates on the same node with information provider, while the global registry locates on a public node that can be accessed by any user in system. Each piece of network-accessed information has a description document that serves as the descriptor of information. The descriptor contains the necessary meta-information to integrate multiple information sources into target information, and plays an important role in Loglo architecture. Built on Web Services, Loglo offers information to the requestor with dedicated service-IIS, and supports the loose integration of information. We design a prototype of Loglo and implement the integration of information in several databases, in pure text files and from sensors.
