OS Open Linked Identifiers

OS Open Linked Identifiers provides authoritative relationship between UPRNs, USRNs, TOIDs and meta data to enable reliable matching; for greater data connectivity.
Authoritative relationships
OS Open Linked Identifiers is a dataset containing the authoritative relationships between Unique Property Reference Numbers (UPRNs), Unique Street Reference Numbers (USRNs) and Topographic Object Identifiers (TOIDs). Watch our OS Open Linked Identifiers introduction video.

Better visualisation
Connecting addresses with road features enables more related data to be joined together which simplifies a number of valuable workflows. Linking these features to graphical elements of OS MasterMap products enables better visualisation of the data related to them.

Find all addresses on a road
Link data related to an address with its building footprint. Validate an addresses UPRN with the name of the road that accesses it. Validate a streets USRN with the name of the road it relates to.

OS开放链接标识符提供权威的UPRN（唯一物业参考编号）、USRN（唯一街道参考编号）和TOID（地形对象标识符）之间的关系，以及元数据，以实现可靠的匹配；并促进数据连接性的增强。
权威关系
OS开放链接标识符是一个包含唯一物业参考编号（UPRNs）、唯一街道参考编号（USRNs）和地形对象标识符（TOIDs）之间权威关系的数据库。请参阅我们的OS开放链接标识符介绍视频。
更佳的可视化
通过将地址与道路特征相连接，可以整合更多相关数据，从而简化多项有价值的流程。将此类特征与OS主地图产品的图形元素相链接，有助于更好地可视化与之相关的数据。
查找道路上的所有地址
将地址相关的数据与其建筑足迹相连接。通过接入该地址的道路名称验证地址的UPRN。通过相关道路的名称验证街道的USRN。
