“…Of course, semantic changes are inevitable; however, it is the deprecation processes -ensuring backwards compatibility and communicating version changes -that badly require clear planning and interoperability. Furthermore, in line with the infrastructure presented in this article, application developers indicate the desire for "machine-readable, API-based access to version history" in vocabulary registries as well (Dunsire et al, 2012).…”

“…Another issue related to usability is the lack of clear schema evolution management for Linked Open Data sets. For instance, common knowledge bases DBpedia and VIAF have both introduced significant changes to the schema over time, aggravating the reproducibility problem and contributing to the vocabulary chaos mentioned in the “Introduction.” In the continuing effort to expose LAM information as Linked Data to increase visibility (Miller and Ogbuji, 2015), Dunsire et al (2012) urged to double efforts on supporting infrastructure, along with “guiding principles and best practices around reuse, extension of existing vocabularies, as well as development of new vocabularies.” Of course, semantic changes are inevitable; however, it is the deprecation processes – ensuring backwards compatibility and communicating version changes – that badly require clear planning and interoperability.

“…The slow adoption is usually attributed to the vocabulary chaos (Dunsire et al , 2012), resulting from poor practices in vocabulary management, development, and reuse. But, Miller and Ogbuji (2015) argued that the details about vocabularies and modeling can gradually be refined as we go along, and that the first goal should be to increase the visibility of library collections on the Web, to establish the Visible Library.…”

This paper details a low-cost, low-maintenance publishing strategy aimed at unlocking the value of Linked Data collections held by libraries, archives and museums. Design/methodology/approach The shortcomings of commonly used Linked Data publishing approaches are identified, and the current lack of substantial collections of Linked Data exposed by libraries, archives and museums is considered. To improve on the discussed status quo, a novel approach for publishing Linked Data is proposed and demonstrated by means of an archive of DBpedia versions, which is queried in combination with other Linked Data sources. Findings We show that our approach makes publishing Linked Data archives easy and affordable, and supports distributed querying without causing untenable load on the Linked Data sources. Practical implications The proposed approach significantly lowers the barrier for publishing, maintaining, and making Linked Data collections queryable. As such, it offers the potential to substantially grow the distributed network of queryable Linked Data sources. Because the approach supports querying without causing unacceptable load on the sources, the queryable interfaces are expected to be more reliable, allowing them to become integral building blocks of robust applications that leverage distributed Linked Data sources. Originality/value The novel publishing strategy significantly lowers the technical and financial barriers that libraries, archives and museums face when attempting to publish Linked Data collections. The proposed approach yields Linked Data sources that can reliably be queried, paving the way for applications that leverage distributed Linked Data sources through federated querying. * Corresponding author 2014). In a recent survey conducted by OCLC Research (Smith-Yoshimura, 2014), 96 participants identified 172 Linked Data projects or services being implemented. Of the 76 that were actually described, 67% published Linked Data. These project mostly aimed at bibliographic metadata enrichment, data interlinking, source referencing, unifying data from various sources, and enhancing existing applications. Meanwhile, the size of some available datasets already ranges between tens of millions and billions of triples. Prominent examples include WorldCat.org (15 billion), Europeana (4 billion), The European Library (2 billion), Library of Congress (500 million) and the British Library (100 million). Efforts are currently ongoing in a wide range of domains (Mitchell, 2015), including electronic thesis and dissertations (ETD) (Mak et al.

“…Moreover it advances the conceptualization of the semantic web by arguing that the legacy metadata based on these established principles and practices should be carried further into the new technological environment of linked open data, lossless as to the information provided. Strategies and methods for doing so, as well as enabling "dumbing-up" to simpler or less granular statements such as dublincore.org or schema.org in order to interoperate data content have already been researched and some solutions proposed (Dunsire, 2012;Dunsire et al, 2012). Moreover, research in and publishing of bibliographic standards and conceptual models in RDF (Resource Description Framework) has shown that the present ways of representing them for humans to read should be transformed in a way also for machines to process and infer the meaning of metadata that result from applying them (Willer and Dunsire, 2013).…”

Metadata for the Information Multiverse

In today's Information Multiverse there are pressing societal, ethical and educational, as well as intellectual reasons why, rather than simplifying and reducing or streamlining, we should actually be complexifying and increasing our efforts to generate metadata that identifies, collocates, contextualizes, authenticates and enfranchises. Such metadata should not only draw upon, but should also simultaneously incorporate rethinking of fundamental and long-established bibliographic and archival principles in light of the plural and increasingly post-physical nature of the Information Multiverse. Our ongoing research is modeling an Information Multiverse approach to metadata by identifying ways in which these complexified principles can be embedded in local, community and global (i.e., web) metadata infrastructures. Their underlying references to common concepts additionally open up the possibility of interoperability and re-use, and, outside the silos of professional/information fields, linking and navigation.

“…54 Dunsire et al believe that while there are challenges in reusing other metadata and in trying to align new metadata with existing vocabularies, this type of mapping and alignment will best serve the Semantic Web in the future. 55 As a popular controlled vocabulary for subject terms, LCSH was frequently discussed in the literature. For a basic introduction, Broughton's book, Essential Library of Congress Subject Headings, provides an overview of LCSH and is geared toward UK catalogers who might be unfamiliar with the controlled vocabulary.…”
