NOT WELL-FORMED OR INVALID. NOW WHAT?: Towards a formalized workflow for format validation error treatment
No full textFile format validation – we all use it and we all run into problems when files do not validate. Though a core process within digital preservation practice, little progress has been made in shared documentation and discussion of processes used to treat file format validation errors. This paper aims to close that gap. A basic workflow for handling validation errors is proposed and visualized, and in a second step tested against two TIFF and two PDF validation errors of varying severity. Observations made are fed back into the workflow diagram. The outcome shall provide a first step towards shared digital preservation practice in the currently largely neglected field of method formalization for file format validation error treatment

„Daten Archivieren”: Lebensabschnitt oder komplementärer Gesamtprozess? Gemeinsamkeiten und Unterschiede in Forschungsdatenmanagement und Langzeitarchivierung im deutschsprachigen Raum
No full textWas ist digitale Langzeitarchivierung? Und wann findet sie statt? Zur Beantwortung dieser Fragen sowie zur Ermittlung von Möglichkeiten einer stärkeren Kooperation untersucht dieser Beitrag die Definition und Verortung von Langzeitarchivierung innerhalb der deutschsprachigen Communities anhand von zwei weit verbreiteten Werkzeugen: dem Datenlebenszyklusmodell sowie dem nestor Siegel Kriterienkatalog. Durch ein Mapping der nestor Siegel Kriterien auf Aufgaben der Lebensabschnitte wird aufgezeigt, dass Archivierung von Beginn an mitgedacht werden muss
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
PREMIS Rights - The Rights Entity Revision

Short Paper: The 2022 Revision of the PREMIS Rights Entity
Authors of the short paper: Karin Bredenberg, Bertrand Caron, Leslie Johnston, Micky Lindlar, Jack O'Sullivan, Sarah Romkey, Marjolein Steeman
As digital preservation practice has matured, our understanding of what is covered by the Rights landscape broadened significantly. However, the Rights entity in the PREMIS data model has not kept pace with these changes, undergoing only minor revisions. In 2019, the PREMIS Editorial Committee formed a working group on Rights to review how the entity could be changed to better reflect the evolving use cases of our community. The initial phase of this work has involved gathering use cases in order to perform a gap analysis with the current definition of Rights within the PREMIS model. Ahead of an official White Paper describing the scope of the revisions to be considered, this paper presents a discussion of the use cases that have informed this work, and the gaps we have identified, before briefly outlining the next steps to be taken
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
