DOI (Digital Object Identifier)
All plenary lectures, oral presentations, including posters presented during round tables will be published as digital documents, with a Digital Object Identifier (DOI ; http://www.doi.org).
A DOI provides a means of persistently identifying a piece of intellectual property on a digital network and associating it with related current data in a structured extensible way. A DOI can apply to any form of intellectual property expressed in any digital environment. DOIs can be considered as "the bar code for intellectual property": like the physical bar code, they are enabling tools for use all through the supply chain to add value and save cost.
A DOI differs from commonly used internet pointers to material such as the URL because it identifies an object as a first-class entity, not simply the place where the object is located. The DOI identifies an entity directly, not some attribute of an object (an address is an attribute of a thing, whereas the thing itself is a first class object).
A DOI also differs from commonly used identifiers of intellectual property such as standard bibliographic and related identifiers (ISBN, ISRC, etc) because it can be associated with defined services and is immediately actionable on a network.
A DOI is an implementation of the Internet concepts of Uniform Resource Name and Universal Resource Identifier. A DOI differs from abstract naming specifications such as URI in that it is a defined implementation complete with social and technical infrastructure, ready to use. Information about a digital object may change over time, including where to find it, but its DOI will not change.
The DOI system provides a framework for persistent identification, managing intellectual content. The system is managed by the International DOI Foundation, an open membership consortium including both commercial and non-commercial partners, and has recently been accepted for standardisation within ISO.
Using DOIs as identifiers makes managing intellectual property in a networked environment much easier and more convenient, and allows the construction of automated services and transactions.
