最近在找一些数据，感觉Linked Open Data是一个方向（LOD），但不知道为何，LOD的数据似乎在快速增长，发展速度却不尽人意。估计与数据质量（可用性）及商业化能力有关。
Linked Data - Connect Distributed Data across the Web
关联数据—通过Web链接分布式数据
Linked Data is about using the Web to connect related data that wasn’t previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. More specifically, Wikipedia defines Linked Data as “a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF.”
This site exists to provide a home for, or pointers to, resources from across the Linked Data community.
关联数据是指使用Web连接以前没有链接过的相关数据，或者使用Web降低当前使用其他方法链接数据的障碍。更具体地说，维基百科把关联数据定义为“用于描述采用URI和RDF方式存在于Web网络的公开、共享和链接碎片化数据、信息和知识的最佳实践的一个术语."
http://linkeddata.org站点的存在是为了为关联数据社区的资源提供一个主页或指向这些资源的指针。
