Lessons Learned in Implementing the Extended Date/Time Format in a Large Digital Library
No full textIn 2012, the University of North Texas (UNT) Libraries implemented the Library
of Congress Extended Date/Time Format (EDTF) into the metadata guidelines for their digital holdings
which now contain more than 460,000 records. This paper discusses the evaluation process to identify
the number of previously-existing dates that meet EDTF standards and those that need to be edited for
conformance. It also outlines practical steps used for implementing the standard, such as date
validation for metadata creators and changes to date displays for public users. Finally, it presents
some of the challenges encountered during the implementation process and considerations for other
institutions that may want to use the EDTF
Realising a Federation of Repositories of Reusable Metadata
No full textSemantic assets and the agreements associated with them are essential elements for
organisations to understand the meaning of the information they exchange -- without them this information
would be of little use. In order to facilitate the access of public administrations in Europe to reusable
semantic assets, the Interoperability Solutions for European Public Administrations Programme of the
European Commission (ISA Programme) has been running for the last 3 years an action on syndicating content
from different semantic asset repositories and making it available through a single point of access. In
this paper we present the current state of the federation of semantic asset repositories on Joinup, namely
a set of online collections of semantic assets maintained by public administrations, standardisation
organisations and businesses, which currently counts more than 1500 semantic assets from 21 partner
organisations, described using the Asset Description Metadata Schema (ADMS)
Implementation of a Linked Open Data Solution for the Statistics Agency of Cantabria's Metadata and Data Bank
Get PDFStatistics is a fundamental piece inside the Open Government philosophy,
being a basic tool for citizens to know and make informed decisions about the society in which
they participate. Due to the great number of organizations and agencies that collect, process
and publish statistical data all over the world, several standards and methodologies for
information exchange have been created in recent years in order to improve interoperability
between data producers and consumers, of which SDMX is one of the most renowned examples.
Despite having been developed independently of this, the global Semantic Web effort (backed
mainly by the W3C-driven Linked Open Data initiatives) presents itself as an extremely useful
tool for publishing both completely contextualized metadata and data, therefore making them
easily understandable and processable by third parties. This report details the changes made
to the IT systems of the Statistical Agency of Cantabria (Instituto Cántabro de Estadística,
ICANE) with the purpose of implementing a Linked Open Data solution for its website and
statistical data bank, making all data and metadata published by this Agency available not
only to humans, but to automatized consumers, too. Multiple standards, recommendations and
vocabularies were used for this task, ranging from Dublin Core metadata RDFa tagging, through
the creation of several SKOS concept schemes, to providing statistical data using the RDF
Data Cube vocabulary
Using Dublin Core Standard for the Metadata Description of Transport Statistics -- Practical Experience from a Project Dedicated to the Set-Up of an Interlinked Statistics Portal
No full textThe analysis of data on transport developments is one major objective in the transport
research focus of the German Aerospace Center (DLR). Following this objective, DLR’s Institute for Transport
Research (VF) offers with the Clearing House of Transport and Mobility a unique collection of publicly
funded travel and mobility surveys for Germany and is official provider for German household surveys
and statistics. Additionally, information about similar statistical data sets and data portals in Europe
is made available. The Institute of Air Transport and Airport Research (FW) as second DLR institute in
the mentioned field provides with the "MONITOR" portal detailed information and statistics concerning
air transport developments. With a set of indicators the institute performs furthermore analyses of the
global long-term air transport development regarding air traffic and financial performance besides
sustainability issues. As both institutes use the Dublin Core Standard for the description of the data
sources in use, in 2011 the idea came up to realise a common (meta-)data repository for interested
users which have the need to combine and investigate different transport statistics. Accordingly,
the project "STRADA@DLR" (Search TRAnsport DAta @ DLR) was launched in cooperation with DLR's Facility
on Simulations and Software Technology (SC) to create an external search and analysis system allowing
directed access to the mentioned data repositories. In this context, the presented project report
discusses the usage of Dublin Core Standard in both institutes, as well as the organisational challenges
and the technical approach in order to elaborate a harmonised metadata scheme for the implementation of
the STRADA@DLR portal
IN2N: Cross-institutional Authority Collaboration
No full textThe paper describes the efforts taking place in the Cross-institutional Authority
Collaboration (Institutionenübergreifende Integration von Normdaten, IN2N) project. This pilot project,
executed in cooperation of the German National Library and the German Film Institute, aims to establish
new collaboration models to improve cross-domain authority maintenance. The paper outlines applied
strategies for making a shared infrastructure available as well as workflows for exchanging data about
persons; interface enhancements to benefit from innovative web approaches; and cross-institutional
data search and representation solutions. Furthermore, we discuss specific boundary conditions for
an interoperable cataloguing environment
With a Focused Intent: Evolution of DCMI as a Research Community
No full textThe Dublin Core Metadata Initiative (DCMI) has played a pivotal role in developing
and nurturing a metadata domain. DCMI’s conference has become an international venue for metadata
researchers and professionals. The purpose of this study is to discover the epistemological
consensus and social semantics, if any, of a metadata domain based in DCMI conferences. Specifically,
we will identify the patterns of emergent and evolving themes over time. To do so we use bibliometric
tools including co-word analysis and author co-citation analysis of the DCMI conferences from 2001-2012.
The results show a domain with an underlying teleology (Dublin Core metadata) and with social semantics,
represented by semantic coherence in the use of terms. Social semantics also demonstrates shared
epistemology as revealed by the co-citation perceptions of the domain. The domain clearly has a
focused intent, albeit with a limited focus. User groups are missing from the domain’s definition
as it emerges in this analysis. Also, there is much room for the domain to nurture so-far under-represented
research topics
Approaches to Building Metadata for Data Curation
No full textIn National Taiwan University (NTU), the Library aims to provide data curation
services for university researchers from different research fields, particularly focusing on those
from small sciences. In this paper, we will first investigate existing metadata schemas used for data
curation services in North America and Europe. Next, we will attempt to develop an application profile,
proposing metadata fields to be applied to data curation services in NTU. Finally, we will discuss our
findings in this study, and take further action to develop a repository platform
ZBW Labs: Publish Projects as Linked Data
No full textZBW Labs (http://zbw.eu/labs) gives insight into software developments of the
German National Library for Economics (ZBW). It presents applications and (web) services in an
experimental or beta state. In order to make information about these projects available on the web
of data, the underlying content management system Drupal is used to add semantic (RDFa) markup,
combing the DOAP (description of a project), schema.org and DC vocabularies. Though Drupal 7 has
RDF support built in natively, some customizations were required to make Linked Data URIs and
nested property structures available
Find and Combine Vocabularies to Design Metadata Application Profiles using Schema Registries and LOD Resources
No full textMetadata schema which defines constraints about metadata records is a fundamental
resource for metadata interoperability. Building interoperable metadata schema has been a main topic of
the Dublin Core since its early days. It is important to make use of existing metadata schema to develop
a new schema in order to minimize newly defines metadata vocabularies, which is a very basic consensus
that DCMI has developed. In order to improve usability of existing metadata schemas to develop new
schemas, it is important to improve usability of information about metadata schema publicly available
on the Internet. This study is aimed to develop a technology to help metadata schema designers find
useful metadata schemas and use those schemas for the metadata schema development. Key concepts used
in this study are Description Set Profiles (DSP) as a formal basis of metadata schema and Linked Open
Data (LOD) as a framework to connect metadata schema resources. In this paper, we first analyse
requirements for metadata schema search and reuse following introduction and discussion on related
works. Then, it presents a set of guidelines to find and combine metadata vocabularies and a technology
to help develop metadata schemas
