URLs (Persistent Uniform Resource Locators) are Web addresses that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. Instead of resolving directly to Web resources, PURLs provide a level of indirection that allows the underlying Web addresses of resources to change over time without negatively affecting systems that depend on them. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons.

"SWAG is creating a strong infrastructure for the Semantic Web, whilst working with various members of the Web community to ensure data interoperability. The SWAG Dictionary, a database of terms for the Semantic Web, is our first important project to that end. Our work should always be available at our PURL (persistent URL) as described in our URI Persistence Policy."
