“…This study addresses the research gap in the area of implementation of RDA standard in authority data that are crucial for providing adequate access to information. Our quantitative analysis of change in RDA-based authority data reveals the lower overall level of editing activity than that observed by previous research for RDA-based bibliographic metadata (Zavalina, Zavalin, & Miksa, 2016). Results of our study demonstrate higher editing activity for meeting name and personal name authority data than for three other types of authority records.…”

Information community creates, maintains and shares authority data through large‐scale databases of standardized digital records that describe persons, institutions, places, events, and works, as well as relations between them. This submission presents some results of the content analysis study that explores the authority data change over time in response to change in standards. We analysed over 400 thousand of authority records that comply to the new standard, Resource Description and Access (RDA) and are available through the OCLC database. Records were obtained at two data collection points, with an interval of 22 months. Our analysis identified RDA‐based authority data elements that are widely applied and the ones that need more attention by record creators. Findings reveal a significant increase over time in the level of application of some data elements, including several of the Linked Data‐enabling elements. This study contributes to the understanding of metadata change and its relation to functionality of authority records and improved information access. Directions for future research are suggested.

“…More recently, the DPLA in the US (2013–present) has expanded these efforts, similar to the Europeana project in the European Union (2008–present). Research using these large aggregations has included a number of quantitative analysis studies (Eklund et al , 2009; Greenberg, 2001; Tarver et al , 2015; Ward, 2003; Zavalina et al , 2016) to assess particular quality aspects. Generally, these aspects report on field usage (Shreeves et al , 2005) or evaluation of values within a particular field, such as the Dublin Core subject (Harper, 2016; Tarver et al , 2015) or date fields (Zavalina et al , 2015).…”

Purpose This study furthers metadata quality research by providing complementary network-based metrics and insights to analyze metadata records and identify areas for improvement. Design/methodology/approach Metadata record graphs apply network analysis to metadata field values; this study evaluates the interconnectedness of subjects within each Hub aggregated into the Digital Public Library of America. It also reviews the effects of NACO normalization – simulating revision of values for consistency – and breaking up pre-coordinated subject headings – to simulate applying the Faceted Application of Subject Terminology to Library of Congress Subject Headings. Findings Network statistics complement count- or value-based metrics by providing context related to the number of records a user might actually find starting from one item and moving to others via shared subject values. Additionally, connectivity increases through the normalization of values to correct or adjust for formatting differences or by breaking pre-coordinated subject strings into separate topics. Research limitations/implications This analysis focuses on exact-string matches, which is the lowest-common denominator for searching, although many search engines and digital library indexes may use less stringent matching methods. In terms of practical implications for evaluating or improving subjects in metadata, the normalization components demonstrate where resources may be most effectively allocated for these activities (depending on a collection). Originality/value Although the individual components of this research are not particularly novel, network analysis has not generally been applied to metadata analysis. This research furthers previous studies related to metadata quality analysis of aggregations and digital collections in general.

“…Major changes in metadata standards usually prompt change in existing metadata records to bring them to conformance with the new standards (e.g., Thornburg & Oskins, 2007). Several studies examined the change in small samples of library metadata records in response to transition to RDA (Zavalina, Shakeri, & Kizhakkethil, 2015; Zavalina, Zavalin, & Miksa, 2016b; Zavalina and Zavalin, 2018). The only study so far that focused specifically on change over time in subject metadata in RDA‐based bibliographic records (Zavalina, Shakeri, & Kizhakkethil, 2016a) relied on a small sample and did not examine any changes in records after 2015.…”

Study reported in this paper analyzed over twenty thousand machine-readable library metadata records in MARC 21 bibliographic format that are based on Resource Description and Access (RDA) standard. The focus of this analysis is on change in subject metadata-data elements designed for representing the aboutness of information objectsover a 6-year period between 2014 and 2020. The analyzed dataset is the entire population of the records representing English-language video recordings in DVD format in WorldCat database as of one year after official transition to RDA data content standard in library metadata creation. Analysis of metadata representing audiovisual materials is needed as audiovisual metadata practices tend to differ from those for other materials due to high occurrence of unique resources. The study includes quantitative and qualitative analyses into the change in the application of data elements (fields and subfields) over time and categorizes the observed change.
