ID@URI is an identifier format proposed by the DIALOG research project of the Helsinki University of Technology for identifying and linking tangible "things" to their information sources on the Internet (the "Internet of Things").
Dialog started off with the project to develop a forwarder independent tracking-and-tracing system for worldwide project deliveries. The URI can be a URL-format computer address (e.g. 'www.some_company.com') and ID is a serial number or any other unique number at the URI indicated.
ID@URI has the same essential properties as the EPC/ONS standards proposed by the AutoID Center at MIT, i.e. it can be guaranteed to be globally unique and it indicates where the information about the item is located. ID@URI can be printed as text, barcode or programmed into a (programmable) RFID chip. In a tracking application, URI is normally set to the company that needs the tracking data. In product data access applications, it could be the manufacturer of the product.
An open source community was started in 2003 for further development of the DIALOG Java-based software components, which cover driver architecture for RFID and barcode readers, client-server communication and information fetch/update to company databases.
Since June 2006, the concept of ID@URI is also being used and further developed by the TraSer EU project consortium.
