The purpose of this community is to setup and maintain a secure, permanent URL re-direction service for the Web. This service, located at w3id.org, is run exclusively by members of the W3C Permanent Identifier Community Group.
Web applications that deal with Linked Data often need to specify and use URLs that are very stable. They utilize services such as the one run by this community to ensure that applications using their URLs will always be re-directed to a working website. The concept operates much like a switchboard, connecting requests for information with the true location of the information on the Web. Entries in the switchboard can be reconfigured to point to a new location if the old location stops working.
There are a growing group of companies that have pledged responsibility to ensure the operation of this community-driven service. These companies are: Digital Bazaar, 3 Round Stones, OpenLink Software, and Applied Testing and Technology. They are responsible for all administrative tasks associated with operating the service. The social contract between these companies gives each of them full access to all information required to maintain and operate the website. The agreement is setup such that a number of these companies could fail, lose interest, or become unresponsive for long periods of time without negatively affecting the operation of the site.
The service operates in HTTPS-only mode to ensure end-to-end security. This means that it may be used for Linked Data applications that require high levels of security such as those found in the financial, medical, and public infrastructure sectors.
All identifiers associated with the service are intended to be around for as long as the Web is around. This means decades, if not centuries. If the final destination for popular identifiers used by this service fail in such a way as to be a major inconvenience or danger to the Web, the community will mirror the information for the popular identifier and setup a working redirect to restore service to the rest of the Web.
