Discovering Scholarly Orphans Using ORCID
Archival efforts such as (C)LOCKSS and Portico are in place to ensure the
longevity of traditional scholarly resources like journal articles. At the same
time, researchers are depositing a broad variety of other scholarly artifacts
into emerging online portals that are designed to support web-based
scholarship. These web-native scholarly objects are largely neglected by
current archival practices and hence they become scholarly orphans. We
therefore argue for a novel paradigm that is tailored towards archiving these
scholarly orphans. We are investigating the feasibility of using Open
Researcher and Contributor ID (ORCID) as a supporting infrastructure for the
process of discovery of web identities and scholarly orphans for active
researchers. We analyze ORCID in terms of coverage of researchers, subjects,
and location and assess the richness of its profiles in terms of web identities
and scholarly artifacts. We find that ORCID currently lacks in all considered
aspects and hence can only be considered in conjunction with other discovery
sources. However, ORCID is growing fast so there is potential that it could
achieve a satisfactory level of coverage and richness in the near future.Comment: 10 pages, 5 figures, 5 tables accepted for publication at JCDL 201
Extending Sitemaps for ResourceSync
The documents used in the ResourceSync synchronization framework are based on
the widely adopted document format defined by the Sitemap protocol. In order to
address requirements of the framework, extensions to the Sitemap format were
necessary. This short paper describes the concerns we had about introducing
such extensions, the tests we did to evaluate their validity, and aspects of
the framework to address them.Comment: 4 pages, 6 listings, accepted at JCDL 201
Access Interfaces for Open Archival Information Systems based on the OAI-PMH and the OpenURL Framework for Context-Sensitive Services
In recent years, a variety of digital repository and archival systems have
been developed and adopted. All of these systems aim at hosting a variety of
compound digital assets and at providing tools for storing, managing and
accessing those assets. This paper will focus on the definition of common and
standardized access interfaces that could be deployed across such diverse
digital respository and archival systems. The proposed interfaces are based on
the two formal specifications that have recently emerged from the Digital
Library community: The Open Archive Initiative Protocol for Metadata Harvesting
(OAI-PMH) and the NISO OpenURL Framework for Context-Sensitive Services
(OpenURL Standard). As will be described, the former allows for the retrieval
of batches of XML-based representations of digital assets, while the latter
facilitates the retrieval of disseminations of a specific digital asset or of
one or more of its constituents. The core properties of the proposed interfaces
are explained in terms of the Reference Model for an Open Archival Information
System (OAIS).Comment: Accepted paper for PV 2005 "Ensuring Long-term Preservation and

Analyzing the Persistence of Referenced Web Resources with Memento
In this paper we present the results of a study into the persistence and
availability of web resources referenced from papers in scholarly repositories.
Two repositories with different characteristics, arXiv and the UNT digital
library, are studied to determine if the nature of the repository, or of its
content, has a bearing on the availability of the web resources cited by that
content. Memento makes it possible to automate discovery of archived resources
and to consider the time between the publication of the research and the
archiving of the referenced URLs. This automation allows us to process more
than 160000 URLs, the largest known such study, and the repository metadata
allows consideration of the results by discipline. The results are startling:
45% (66096) of the URLs referenced from arXiv still exist, but are not
preserved for future generations, and 28% of resources referenced by UNT papers
have been lost. Moving forwards, we provide some initial recommendations,
including that repositories should publish URL lists extracted from papers that
could be used as seeds for web archiving systems.Comment: 4 pages, 5 figures. Accepted to Open Repositories 2011 Conferenc
