Preservation Of Metadata Research Articles

A conceptual framework for the path of digital preservation of intangible cultural heritage: A thematic review

Abstract The digital preservation strategy could be concerned from the perspective of the life cycle of a digital resource, which includes creation, use, management, and preservation, which has been implemented widely for intangible cultural heritage (ICH) safeguarding. Nonetheless, the depth of development of the metaverse, digital humanities, etc., raises the question of which direction the most up-to-date strategic and theoretical developments are headed in a wider context. As a result, this study will evaluate articles from 2018 to 2024 to determine the trends in digital preservation strategies at ICH. With a thematic review (TR) instrument, a total of 24 articles out of 129 peer-reviewed database articles from the WoS and Scopus databases were extracted and screened, which cover the application of digital preservation strategies in ICH conservation. ATLAS.ti 9, the analysis software, produced quantitative results showing trends in this study. The thematic analysis reveals four key themes: computer technology, cultural transmission, strategy implementation, and metadata preservation. The authors propose a conceptual framework that establishes the logical connection between the four themes and outlines the path for ICH digital preservation. The findings provide valuable insights for researchers and practitioners involved in the digital preservation strategy of ICH, as well as mapping the scope, challenges, and practices of these initiatives.

SARS-CoV-2 viral titer measurements in Ontario, Canada wastewaters throughout the COVID-19 pandemic

During the COVID-19 pandemic, the Province of Ontario, Canada, launched a wastewater surveillance program to monitor SARS-CoV-2, inspired by the early work and successful forecasts of COVID-19 waves in the city of Ottawa, Ontario. This manuscript presents a dataset from January 1, 2021, to March 31, 2023, with RT-qPCR results for SARS-CoV-2 genes and PMMoV from 107 sites across all 34 public health units in Ontario, covering 72% of the province’s and 26.2% of Canada’s population. Sampling occurred 2–7 times weekly, including geographical coordinates, serviced populations, physico-chemical water characteristics, and flowrates. In doing so, this manuscript ensures data availability and metadata preservation to support future research and epidemic preparedness through detailed analyses and modeling. The dataset has been crucial for public health in tracking disease locally, especially with the rise of the Omicron variant and the decline in clinical testing, highlighting wastewater-based surveillance’s role in estimating disease incidence in Ontario.

Malta’s ISBN Database and the Benefits of Open Data

In 2016, the National Book Council, the ISBN agency for Malta, released its ISBN database online. A few months later, the ISBN database was enhanced with an open-data feature that enables users to download the search results in a single file with read and write access. The database includes all the ISBN data of Malta except for some records and data that were lost during the period before 2013 when paper data storage of ISBN records was the common practice. The implementation of an ISBN electronic database now ensures that no data go missing and facilitates the preservation of metadata. As added value, the open-data system provides access to all of the ISBN records as listed in the database, which means that virtually all of the ISBN data elements can be downloaded from the database. Researchers, publishers, authors, and booksellers all stand to benefit from this open ISBN data system.

ENHANCED LOAD BALANCING STRATEGY IN HETEROGENEOUS PEER-TO-PEER NETWORKS

Existing P2P systems provide a Duty Cycle Data Appropriation (DCDA) Technique allocate objects based on ranking among “peer nodes” in a method that result in various nodes containing times as numerous objects as the standard node. Further disparity mig ht effect owing to non-uniform allocation of object s in the identifier break and a high amount of heterogene ity in objective loads and node capabilities. With that, a node’s load might differ seriously over time as the system can be projected to practice incessant oper ations of objects. Introduced an algorithm for load balanc ing in such heterogeneous, active P2P systems. Fore most contributions are: (1) suggest a fully dispersed me thod to preserve the record of file access informat ion. This information is employed to forecast the prospe ct file access frequencies and sustain the load all ocation and redeployment operations; (2) Plan a novel load balancing algorithm, which obtains the file access record and peer heterogeneity properties to establi sh the load allocation. Enhanced Load Balancing Str ategy in Heterogenous P2P Network (ELBSHN) algorithm engender the best load allocation resolution when a novel peer enters, it also be capable to vigorously achieve the load redeployment through system runni ng time if congested peers emerged. In ELBSHN algorithm, no virtual servers are employed; consequently encompass less processing overhead on the exclusive routing metadata preservation. An experimental evaluation is conducted using the Heterogeneous pee r networks data extracted from the large internet service providers to estimate the performance of th e proposed enhanced load balancing strategy. Simula tion results illustrate that in the features of quick on sets and exits of objects of extensively changeable load, algorithm attains load balancing for system utiliza tions as high as 90% while affecting only regarding 8% of the load that appears into the system.

JPEG 2000: A Potential Solution for Archiving HDTV Content

Selecting an adequate file format for archiving has always been a complex issue. Several formats are available from a variety of vendors but in addition to the issue of storage media deterioration there is always the serious threat of technology becoming obsolete or no longer being supported by the vendor. Consequently, users experience interoperability during content exchange. Furthermore, with the introduction of HDTV in broadcasting and multiple distribution platforms (Mobile TV, T-DMB, DVB-H, IPTV) and image formats (720p/50, 1080p/50, etc.) compression scalability is now more of a requirement than before. Together with a need for higher quality preservation capability, metadata preservation is also a strong requirement for today's archive formats. JPEG 2000 is a fairly recent ISO open standard, based on wavelet technology. It provides a set of features such as spatial, temporal, and SNR scalability; lossless and lossy compression; and a large support for metadata, all of which are highly valuable for archiving HDTV content. The EBU Technical department has been investigating the JPEG 2000 compression system and, in particular, the best parameters for visually lossless preservation of HDTV content, depending on the format. The subjective quality was assessed at expert viewing sessions using a split screen for quality comparisons. This paper describes features of the JPEG 2000 standard, as well as its advantages and disadvantages in an archival environment. A performance evaluation of JPEG 2000 and recommendation on the JPEG 2000 settings suitable for HDTV archival is given.

El papel de los metadatos en la preservación digital

The problem of preserving digital information has now taken on great importance. As the amount of digital information continues to grow, the concern about maintaining access to this information accessible will increase. As elements for describing digital documents or DLO (Document Like Object), metadata play an important role in providing information about the logical aspects of the DLO they refer to, and consequently, in all the tasks related to preservation. At the same time, metadata are digital information, so their preservation must be borne in mind. In this respect, several projects and work groups have been devoted to studying the use of metadata for digital preservation and the preservation of metadata themselves.
