Data management, chapter 5, part C

The data management for a spacecraft radar was defined in terms of an end-to-end data system, which performs the following three functions: (1) sampling and compaction of data onboard the spacecraft, (2) manipulation of radar data on the ground and (3) conversion of radar measurements to geophysical quantities by means of pattern recognition and other machine techniques. Data processing for imaging radar onboard the spacecraft was examined with the conclusion that several techniques can be used to compact the data before storage. It is recommended that compaction techniques be studied further and that existing aircraft radars be modified to provide digital data so that these compaction techniques can be tested

A Practical Approach in Digitizing Analogue Audio Assets

Today, Broadcast companies are migrating from aTape-based workflow to that File-Based .This not only affectsgrowing number of channels and new ways of broadcasting, butalso it changes the way we store and retrieve our preciouscontents. Such historical essences are transferred to digital onlyonce and used numerous of times, so the method we use fortransferring these materials is so important. Technicalparameters of digitizing from Capturing and scanning to Storagemedia and formats are as important as non-technical conceptslike metadata and Cataloguing. In this paper, a practical methodof transferring Analog materials to digital formats and media ispresented. Suitable formats, backup, metadata and qualitycontrol methods are introduced. A very best practice of digitizingproject at IRIB huge archive will be introduced as a practicalexample

Making Sound Decisions: Institutional Responses to the Crisis in Audio Preservation

Some archives have been quick to respond to the crisis in audio preservation brought on by the combined forces of obsolescence and degradation inherent in legacy audio formats and their playback equipment. These archives have undertaken digitization projects for particular collections or, in a few cases, have digitized the bulk of their audio holdings for preservation. Based on an examination of the literature on audio preservation, however, the responses of some institutions—particularly small and midsized institutions—have been stymied by roadblocks related to cost and expertise. Given the limited time available for archives to migrate audio content, this uneven response threatens to leave an incomplete audio legacy, weighted toward grant-worthy collections with few copyright restrictions at larger, better-resourced institutions. After a review of relevant literature, this article suggests interventions institutions of all sizes can undertake to respond to the crisis in audio preservation including stringent selection and reappraisal projects, strategies for tiered audio digitization using a combination of in-house and vendor-based services, and suggestions for increasing access to high-quality digitization for worthy audio materials

From Grain to Pixel

Film is in a state of rapid change, with the transition from analog to digital profoundly affecting not just filmmaking and distribution, but also the theoretical conceptualization of the medium film and the practice of film archiving. New forms of digital archives are being developed that make use of participatory media to provide a more open form of access than any traditional archive has offered before. Film archives are thus faced with new questions and challenges. From Grain to Pixel attempts to bridge the fields of film archiving and academic research, by addressing the discourse on film ontology and analysing how it affects the role of film archives. Fossati proposes a new theoretization of film archival practice as the starting point for a renewed dialogue between film scholars and film archivists.Het bewegende beeld bevindt zich in een overgangsperiode waarin analoge (fotochemische) film geleidelijk vervangen wordt door digitale film. Deze overgang heeft niet alleen diepgaande invloed op filmproductie en -distributie, maar ook op de manier van archiveren van film en de theoretische conceptualisering van dit medium. Van digitale archieven worden steeds nieuwe vormen ontwikkeld. Deze archieven - digitale filmdatabases en YouTube bijvoorbeeld - maken gebruik van media die participatie van vele gebruikers mogelijk maken en worden zo toegankelijker dan ooit. Ondertussen is er nog onvoldoende dialoog tussen archivarissen en filmwetenschappers. From Grain to Pixel slaat een brug tussen archiveringspraktijken en wetenschappelijk onderzoek dat gebaseerd is op relevante debatten in film- en nieuwe mediastudies. Fossati stelt een nieuwe theorie op voor het archiveren en restaureren van film. Dit biedt mogelijkheden voor een hernieuwde dialoog tussen archivarissen en wetenschappers

Access to recorded interviews: A research agenda

Recorded interviews form a rich basis for scholarly inquiry. Examples include oral histories, community memory projects, and interviews conducted for broadcast media. Emerging technologies offer the potential to radically transform the way in which recorded interviews are made accessible, but this vision will demand substantial investments from a broad range of research communities. This article reviews the present state of practice for making recorded interviews available and the state-of-the-art for key component technologies. A large number of important research issues are identified, and from that set of issues, a coherent research agenda is proposed

Archival time-based media : topologies of preservation and access

textThe analog time-based media of film, videotape, grooved sound recordings and audiotape have emerged as a growing area of concern for cultural institutions. Collectively, these media constitute a rich body of historical evidence and intangible cultural heritage whose varied physical and technological components incur a wide range of preservation needs. The current moment is also one where digitally-enabled technologies for migrating and sharing time-based media appear to hold infinite promise, even as the most vulnerable elements of the historical record embodied in moving images and recorded sound threaten to disappear. This study investigates the preservation of analog time-based media as it exists in local repositories. The study was formed in response to the needs of a specific collection of analog audio open reels containing music recorded at Houston's Andrus Studios dating from the 1960s and early 1970s, and to the task of finding an appropriate repository to acquire the collection. Physical, technological and intellectual aspects of time-based media are articulated in the literature review, study criteria and semi-structured interview questions employed for the study. The findings form a topology of preservation and access activities that exist in local repositories and that contribute to the sustainability of acquiring substantial collections of obsolete time-based media such as the Andrus Studios collection.Informatio

From Grain to Pixel

"In From Grain to Pixel , Giovanna Fossati analyzes the transition from analog to digital film and its profound effects on filmmaking and film archiving. Reflecting on the theoretical conceptualization of the medium itself, Fossati poses significant questions about the status of physical film and the practice of its archival preservation, restoration and presentation. From Grain to Pixel attempts to bridge the fields of film archiving and academic research by addressing the discourse on film's ontology and analyzing how different interpretations of what film is affect the role and practices of film archives. Ultimately, Fossati proposes a novel theorization of film archival practice as the starting point for a renewed dialogue between film scholars and film archivists. Almost a decade after its first publication, this updated edition covers the latest developments in the field. Besides a new general introduction, a new conclusion and extensive updates to each chapter, a novel theoretical framework and a new case study have been added. Giovanna Fossati is chief curator at EYE Filmmuseum and professor of film heritage and digital film culture at the University of Amsterdam.

Cultural Context-Aware Models and IT Applications for the Exploitation of Musical Heritage

Information engineering has always expanded its scope by inspiring innovation in different scientific disciplines. In particular, in the last sixty years, music and engineering have forged a strong connection in the discipline known as “Sound and Music Computing”. Musical heritage is a paradigmatic case that includes several multi-faceted cultural artefacts and traditions. Several issues arise from the analog-digital transfer of cultural objects, concerning their creation, preservation, access, analysis and experiencing. The keystone is the relationship of these digitized cultural objects with their carrier and cultural context. The terms “cultural context” and “cultural context awareness” are delineated, alongside the concepts of contextual information and metadata. Since they maintain the integrity of the object, its meaning and cultural context, their role is critical. This thesis explores three main case studies concerning historical audio recordings and ancient musical instruments, aiming to delineate models to preserve, analyze, access and experience the digital versions of these three prominent examples of musical heritage. The first case study concerns analog magnetic tapes, and, in particular, tape music, a particular experimental music born in the second half of the XX century. This case study has relevant implications from the musicology, philology and archivists’ points of view, since the carrier has a paramount role and the tight connection with its content can easily break during the digitization process or the access phase. With the aim to help musicologists and audio technicians in their work, several tools based on Artificial Intelligence are evaluated in tasks such as the discontinuity detection and equalization recognition. By considering the peculiarities of tape music, the philological problem of stemmatics in digitized audio documents is tackled: an algorithm based on phylogenetic techniques is proposed and assessed, confirming the suitability of these techniques for this task. Then, a methodology for a historically faithful access to digitized tape music recordings is introduced, by considering contextual information and its relationship with the carrier and the replay device. Based on this methodology, an Android app which virtualizes a tape recorder is presented, together with its assessment. Furthermore, two web applications are proposed to faithfully experience digitized 78 rpm discs and magnetic tape recordings, respectively. Finally, a prototype of web application for musicological analysis is presented. This aims to concentrate relevant part of the knowledge acquired in this work into a single interface. The second case study is a corpus of Arab-Andalusian music, suitable for computational research, which opens new opportunities to musicological studies by applying data-driven analysis. The description of the corpus is based on the five criteria formalized in the CompMusic project of the University Pompeu Fabra of Barcelona: purpose, coverage, completeness, quality and re-usability. Four Jupyter notebooks were developed with the aim to provide a useful tool for computational musicologists for analyzing and using data and metadata of such corpus. The third case study concerns an exceptional historical musical instrument: an ancient Pan flute exhibited at the Museum of Archaeological Sciences and Art of the University of Padova. The final objective was the creation of a multimedia installation to valorize this precious artifact and to allow visitors to interact with the archaeological find and to learn its history. The case study provided the opportunity to study a methodology suitable for the valorization of this ancient musical instrument, but also extendible to other artifacts or museum collections. Both the methodology and the resulting multimedia installation are presented, followed by the assessment carried out by a multidisciplinary group of experts
