On Constructing Persistent Identifiers with Persistent Resolution Targets
Persistent Identifiers (PID) are the foundation referencing digital assets in
scientific publications, books, and digital repositories. In its realization,
PIDs contain metadata and resolving targets in form of URLs that point to data
sets located on the network. In contrast to PIDs, the target URLs are typically
changing over time; thus, PIDs need continuous maintenance -- an effort that is
increasing tremendously with the advancement of e-Science and the advent of the
Internet-of-Things (IoT). Nowadays, billions of sensors and data sets are
subject of PID assignment. This paper presents a new approach of embedding
location independent targets into PIDs that allows the creation of
maintenance-free PIDs using content-centric network technology and overlay
networks. For proving the validity of the presented approach, the Handle PID
System is used in conjunction with Magnet Link access information encoding,
state-of-the-art decentralized data distribution with BitTorrent, and Named
Data Networking (NDN) as location-independent data access technology for
networks. Contrasting existing approaches, no green-field implementation of PID
or major modifications of the Handle System is required to enable
location-independent data dissemination with maintenance-free PIDs.Comment: Published IEEE paper of the FedCSIS 2016 (SoFAST-WS'16) conference,

A Framework for Reference Management in the Semantic Web
Much of the semantic web relies upon open and unhindered interoperability between diverse systems. The successful convergence of multiple ontologies and referencing schemes is key. This is hampered by a lack of any means for managing and communicating co-references. We have therefore developed an ontology and framework for the exploration and resolution of potential co-references, in the semantic web at large, that allow the user to a) discover and record uniquely identifying attributes b) interface candidates with and create pipelines of other systems for reference management c) record identified duplicates in a usable and retrievable manner, and d) provide a consistent reference service for accessing them. This paper describes this ontology and a framework of web services designed to support and utilise it
Evaluation of Anonymized ONS Queries
Electronic Product Code (EPC) is the basis of a pervasive infrastructure for
the automatic identification of objects on supply chain applications (e.g.,
pharmaceutical or military applications). This infrastructure relies on the use
of the (1) Radio Frequency Identification (RFID) technology to tag objects in
motion and (2) distributed services providing information about objects via the
Internet. A lookup service, called the Object Name Service (ONS) and based on
the use of the Domain Name System (DNS), can be publicly accessed by EPC
applications looking for information associated with tagged objects. Privacy
issues may affect corporate infrastructures based on EPC technologies if their
lookup service is not properly protected. A possible solution to mitigate these
issues is the use of online anonymity. We present an evaluation experiment that
compares the of use of Tor (The second generation Onion Router) on a global
ONS/DNS setup, with respect to benefits, limitations, and latency.Comment: 14 page
Towards persistent resource identification with the uniform resource name
The exponential growth of the Internet, and the subsequent reliance on the resources it connects, has exposed a clear need for an Internet identifier which remains accessible over time. Such identifiers have been dubbed persistent identifiers owing to the promise of reliability they imply. Persistent naming systems exist at present, however it is the resolution of these systems into what Kunze, (2003) calls persistent actionable identifiers which is the focus of this work. Actionable identifiers can be thought of as identifiers which are accessible in a simple fashion such as through a web browser or through a specific application. This thesis identifies the Uniform Resource Name (URN) as an appropriate identification scheme for persistent resource naming. Evaluation of current URN systems finds that no practical means of global URN resolution is currently available. Two ,new approaches to URN resolution, unique in their use of the Domain Name System (DNS) are introduced. The proposed designs are assessed according to their Usability, Security and Evolution and an implementation described for an example URN namespace of language identifiers
Naming and Addressing Conventions for Digital Resources
This paper discusses the various naming and addressing systems
used to identify and locate resources in the digital environment.
there are various schemes that have been developed for this purpose,
like, URL, URN, URC schemes developed by the IETF (Internet
Engineering Task Force), PURL developed at OCLC. The publishing
industry also has developed the Digital Object Identifier (DOI),
which is being used for rights management of intellectual property.
The specifications and the working of URLs, URNs, URCs, PURLs,
and DOIs are discussed in detail in this paper
Globally unique product identifiers— requirements and solutions to product lifecycle management
Managing product information for product items during their whole lifetime is challenging, especially during their usage and end-of-life phases. A major challenge is how to keep a link between the product item and its associated information, which may be stored in backend systems of different organisations. In this paper, we analyse and compare three approaches for addressing this task, i.e. the EPC Network, DIALOG and WWAI
Recursively invoking Linnaeus: A Taxonomy for Naming Systems
Naming is a central element of a distributed or network system design. Appropriate design choices are central. This paper explores a taxonomy of naming systems, and engineering tradeoffs as an aid to the namespace designer. The three orthogonal components of the taxonomy are the characteristics of the namespace itself, name assignment, and name resolution. Within each of these, we explore a number of distinct characteristics. The position of this paper is that engineering design of naming systems should be informed by the possibilities and tradeoffs that those possibilities represent. The paper includes a review of a sampling of naming system designs that reflect different choices within the taxonomy and discussion about why those choices were made.This effort was sponsored by the Defense Advanced Research Projects Agency (DARPA) and Air Force Research Laboratory, Air Force Materiel Command, USAF, under agreement number F30602-00-2-0553
