Europeana: Moving to Linked Data

Mon, 22 May 2017 07:03:30 +0000

This article describes the pilot project undertaken by Europeana. Its goal was to replace data societies within the cultural heritage domain with "a distributed information continuum enabled by linked open data". Challenges that had to be overcome included: metadata schema interoperability; URI dereferencability; issues of trust and provenance. The project produced the Europeana Data model (EDM) and a "Technical Architecture" for data providers to use when publishing their metadata.

Linked Data Vocabulary Management: Infrastructure Support, Data Integration, and Interoperability

Fri, 05 May 2017 06:59:13 +0000

This article discusses the shift in popular approaches to large-scale metadata management and interoperability. These approaches are rooted in Semantic Web technologies, such as the Resource Description Framework (RDF). In the library community, this trend has accelerated since the W3C re-framed many of the enabling technologies in terms of Linked Open Data (LOD). As more and more RDF-based metadata become available, a lack of established best practices for vocabulary development and management is leading to a certain level of vocabulary chaos. This article discusses strategies for vocabulary publishing, discovery, evaluation, and mapping have the potential to change the conversation significantly.

Design an OWL Ontology Project

Sat, 21 Jan 2017 06:46:40 +0000

This document outlines a project originally from the course "Semantic Web Topics" at LeHigh University. Students are asked to work in teams to design an OWL 2 DL ontology (or set of ontologies) for an application domain of their choice – ideally, this domain should be one they know about. Since students are also expected to create a set of instances that demonstrate the use of the ontology, they should also choose a domain that has data they can access. Ontologies must be valid OWL or OWL 2 DL ontologies and should use the rich modeling constructs of OWL as much as possible. A DL reasoner should be used to ensure that classes are satisfiable and that the ontology does not lead to unintended inferences.

Application Profiles: Exposing and Enforcing Metadata Quality

Abi Evans — Sun, 04 Oct 2015 05:32:27 +0000

This paper explores a range of issues yet to be addressed in the large-scale use of application profiles. While considerable attention has been paid to human-readable application profiles, there is a growing need for machine-readable application profiles that can support quality control mechanisms including, but not limited to, data validation. These issues are examined in the context of the evolving Semantic Web and the DCMI commitment to RDF and the challenges presented.

Providing Machine-readable Application Profiles with OAI-ORE

Abi Evans — Fri, 02 Oct 2015 02:44:25 +0000

This German blog post shares thoughts on how to publish application profiles in a formal machine-readable way. Currently, there doesn't seem to exist any common practice for publishing machine-readable documentations of application profiles. The author attempts here to publish an AP documentation using OAI-ORE. OAI-ORE offers what one needs to represent application profiles – or at least the characteristics of APs we were looking for – in RDF. The question is whether it is also comfortable to create and make use of or whether one should look for a lightweight alternative.

Sharing Context – Publishing Application Profiles with JSON-LD

Abi Evans — Fri, 02 Oct 2015 02:44:25 +0000

This German blog post discusses promoting the re-use of existing vocabularies instead of creating a new one for every application. However, re-using vocabularies doesn't by itself guarantee interoperability on the Web of Linked Data. The post argues that it is not difficult and doesn't take much time to encode the core content of an application profile as a JSON context document. As it is a useful addition to a human-readable documentation of an application profile it may well be worth the effort to publish the core information of an application profile as a JSON-LD context document.

Formalizing Dublin Core Application Profiles Description Set Profiles and Graph Constraints

Abi Evans — Fri, 02 Oct 2015 02:44:25 +0000

This paper describes a proposed formalization of the notion of Applications
Profiles as used in the Dublin Core community. The formalization, called
Description Set Profiles, defines syntactical constraints on metadata records conforming to the DCMI Abstract Model using an XML syntax. The mapping of this formalism to syntax-specific constraint languages such as XML Schema is discussed.

From Content Standard to RDF

Abi Evans — Fri, 02 Oct 2015 02:44:25 +0000

This paper discusses the basic steps in developing an application profile, and the utility of application profiles in constructing and validating bibliographic records using a specific content standard. The paper concludes by observing that Dublin Core application profiles expressed in Resource Description Framework can improve the interoperability of metadata created by specific communities at the
global level of the Semantic Web. Examples from the International Standard Bibliographic Description and RDA: resource description and access are given throughout the paper.

From Interoperability to Harmonization in Metadata Standardization

Abi Evans — Fri, 02 Oct 2015 02:44:25 +0000

In this doctoral thesis, the author presents a solution-oriented analysis of current issues in metadata harmonization. A set of widely used metadata specifications in the domains of learning technology, libraries and the general Web environment have been chosen as targets for the analysis, with a special focus on Dublin Core, IEEE LOM and RDF. Through active participation in several metadata standardization communities, a body of knowledge of harmonization issues has been developed. The thesis concludes that the Resource Description Framework (RDF) is the only existing specification that has the right characteristics to serve as a practical basis for such a harmonization framework, and therefore must be taken into account when designing metadata
specifications.
