A PAC-ID only contains the essentials needed to identify something. Applications often need more, such as a readable name, safety details, or physical properties. PAC-ID Attributes provides a way to retrieve that information.

Unlike many existing interfaces, it does not require custom code for every provider or overly strict conventions. It is structured enough for software to display information consistently, while remaining lightweight and practical.

It is also RDF-ready, so systems that need linked-data compatibility can use it, while others can simply use it as a straightforward metadata interface.
