The Spatial Identifier Reference Framework (SIRF) - A linked spatial data infrastructure for the Web of Data

SIRF is a scalable linked data infrastructure that aims to improve the supply of open, spatially enabled and linked information.

SIRF indexes and integrates spatial identifiers (codes and names used to reference real world locations) from multiple spatial data sets and publishes these as linked data. SIRF provides a means to reliably cross reference identifiers for the same real world location and encodes spatial relationships between features (such as containment and adjacency). This framework of spatial identifiers is used to link information (such as socio-economic statistics) about locations, stored in multiple distributed systems.

SIRF is built using a suite of APIs that support query to find locations, find different representation for these locations and find related information resources.

Several user interfaces that enable access to spatial identifiers and the network of information resources that have been developed include Place SIRF a lightweight search and download application developed using OpenSearch and the SIRF portal

SIRF is being implemented through a series of related projects addressing identified use cases for information communities in a number of countries.

Underpinning SIRF is a broad ranging system of system interoperability research agenda.
