New ISA study: 10 rules and good practices for designing persistent URIs
The internet is increasingly used by governments to communicate with citizens and businesses as well as between public administrations. The rapid development of the internet has led to an increased reliance on URIs (Uniform Resource Identifiers) as identifiers for a wide variety of digital content. When digital content is published online, it can often still be found on the web many years later. URIs therefore need to be future proof i.e. stable and persistent.
To help public administrations improve the way they design and manage their URIs, the ISA programme, in the context of its action on improving semantic interoperability, recently published 10 rules for persistent URIs, reproduced below, in a study on good practices for the publication of URIs. The study looks at 20 cases from EU agencies and services, EU Member States, standardization bodies and other initiatives where URIs have been designed to be persistent.
What is a URI?
In computing, a uniform resource identifier (URI) is a string of characters used to identify a name or a web resource. Such identification enables interaction with representations of the web resource over a network (typically the World Wide Web) using specific protocols. URIs can be classified as locators (URLs), as names (URNs), or as both. A uniform resource name (URN) functions like a person's name, while a uniform resource locator (URL) resembles that person's street address. In other words: the URN defines an item's identity, while the URL provides a method for finding it.
