Big Metadata, Smart Metadata, and Metadata Capital: Toward Greater Synergy Between Data Science and Metadata

Author : Jane Greenberg

Purpose

The purpose of the paper is to provide a framework for addressing the disconnect between metadata and data science. Data science cannot progress without metadata research. This paper takes steps toward advancing the synergy between metadata and data science, and identifies pathways for developing a more cohesive metadata research agenda in data science.

Design/methodology/approach

This paper identifies factors that challenge metadata research in the digital ecosystem, defines metadata and data science, and presents the concepts big metadata, smart metadata, and metadata capital as part of a metadata lingua franca connecting to data science.

Findings

The “utilitarian nature” and “historical and traditional views” of metadata are identified as two intersecting factors that have inhibited metadata research. Big metadata, smart metadata, and metadata capital are presented as part of a metadata lingua franca to help frame research in the data science research space.

Research limitations

There are additional, intersecting factors to consider that likely inhibit metadata research, and other significant metadata concepts to explore.

Practical implications

The immediate contribution of this work is that it may elicit response, critique, revision, or, more significantly, motivate research. The work presented can encourage more researchers to consider the significance of metadata as a research worthy topic within data science and the larger digital ecosystem.

Originality/value

Although metadata research has not kept pace with other data science topics, there is little attention directed to this problem. This is surprising, given that metadata is essential for data science endeavors. This examination synthesizes original and prior scholarship to provide new grounding for metadata research in data science.

High-Quality Metadata and Repository Staffing: Perceptions of United States–Based OpenDOAR Participants

Digital repositories require good metadata, created according to community-based principles that include provisions for interoperability. When metadata is of high quality, digital objects become sharable and metadata can be harvested and reused outside of the local system.

A sample of U.S.-based repository administrators from the OpenDOAR initiative were surveyed to understand aspects of the quality and creation of their metadata, and how their metadata could improve.

Most respondents (65%) thought their metadata was of average quality; none thought their metadata was high quality or poor quality. The discussion argues that increased strategic staffing will alleviate many perceived issues with metadata quality.

OpenDOAR Repositories and Metadata Practices

« In spring 2014, authors from the University of Missouri conducted a nation-wide survey on metadata practices among United States-based OpenDOAR repositories. Examining the repository systems and current practices of metadata in these repositories, researchers collected and analyzed the responses of 23 repositories. Results from this survey include information about the creators of metadata, best practices and resources, and controlled vocabularies. Findings will inform libraries about the current state of repository and metadata choices in open repositories in the United States, especially as they pertain to overarching questions of interoperability. »

Loading Brief MARC Records for Open-Access Books in an Academic Library Online Catalog

Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library’s experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project.

Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection, and because many of the records could be improved using the global update functionality in the catalog.

Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library’s Web page, was considered to be valuable because of the aggregation a catalog provides, and because the Mbooks collection helped fill gaps in the Library’s physical collections.

As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them.

The Strongest Link: Libraries and Linked…

The Strongest Link: Libraries and Linked Data :

« Since 1999 the W3C has been working on a set of Semantic Web standards that have the potential to revolutionize web search. Also known as Linked Data, the Machine-Readable Web, the Web of Data, or Web 3.0, the Semantic Web relies on highly structured metadata that allow computers to understand the relationships between objects. Semantic web standards are complex, and difficult to conceptualize, but they offer solutions to many of the issues that plague libraries, including precise web search, authority control, classification, data portability, and disambiguation. This article will outline some of the benefits that linked data could have for libraries, will discuss some of the non-technical obstacles that we face in moving forward, and will finally offer suggestions for practical ways in which libraries can participate in the development of the semantic web. »

Handling Repository-Related Interoperability Issues: the SONEX Workgroup

Sharing of scholarly content through a network of Open Access repositories is becoming commonplace but there is still need for systematic attention into ways to increase the rate of deposit into, and transfer of content across, the OA repository space. This is a report of the work of a small international group, supported by JISC, with remit to describe, analyse and make recommendations on deposit opportunities and use cases that might provide a framework for project activity geared to the ingest of research papers and other scholarly works.

The multi-authored, multi-institutional work is put forward as the default, and nine use case actors are listed, as deposit agents, with four main use case scenarios. There is also some comment and pointers to projects in Europe which address some of these use case scenarios.

The Simple Publishing Interface (SPI)

The Simple Publishing Interface (SPI) is a new publishing protocol, developed under the auspices of the European Committee for Standardization (CEN) workshop on learning technologies. This protocol aims to facilitate the communication between content producing tools and repositories that persistently manage learning resources and metadata. The SPI work focuses on two problems: (1) facilitating the metadata and resource publication process (publication in this context refers to the ability to ingest metadata and resources); and (2) enabling interoperability between various components in a federation of repositories.

This article discusses the different contexts where a protocol for publishing resources is relevant. SPI contains an abstract domain model and presents several methods that a repository can support. An Atom Publishing Protocol binding is proposed that allows for implementing SPI with a concrete technology and enables interoperability between applications.
