最近在找一些數據，感覺Linked Open Data是一個方向（LOD），但不知道爲何，LOD的數據似乎在快速增長，發展速度卻不盡人意。估計與數據質量（可用性）及商業化能力有關。
Linked Data - Connect Distributed Data across the Web
關聯數據—通過Web鏈接分佈式數據
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.
關聯數據是指使用Web連接以前沒有鏈接過的相關數據，或者使用Web降低當前使用其他方法鏈接數據的障礙。更具體地說，維基百科把關聯數據定義爲“用於描述採用URI和RDF方式存在於Web網絡的公開、共享和鏈接碎片化數據、信息和知識的最佳實踐的一個術語."
http://linkeddata.org站點的存在是爲了爲關聯數據社區的資源提供一個主頁或指向這些資源的指針。
