PIDA is a service providing unique persistent URLs (PURLs) for referencing digital assets on the web. Using our service will help you to ensure that your digital assets remain findable and can be accessed reliably by both humans and machines in the long term. The service provides content negotiation and is thus ideally suited to be used for the development of ontologies.
Some of PIDA’s key features are:
provides persistent and globally unique identifiers (PURLs)
easy to create and update
supports content negotiation (i.e. HTML, OWL, TTL, RDF)
secure https communications protocol
persistent for 10+ years
