Digital preservation is a significant challenge for cultural heritage institutions and other repositories of digital information resources. Recognizing the critical role of metadata in any successful digital preservation strategy, the Preservation Metadata Implementation Strategies (PREMIS) has been extremely influential on providing a "core" set of preservation metadata elements that support the digital preservation process. However, there is no evidence, in the form of previous research, as to what factors explain and predict the level of adoption of PREMIS. This research focused on identifying factors that affect the adoption of PREMIS in cultural heritage institutions. This study employed a web-based survey to collect data from 123 participants in 20 country as well as a semi-structured, follow-up telephone interview with a smaller sample of the survey respondents. Roger's diffusion of innovation theory was used as a theoretical framework. The main constructs considered for the study were relative advantage, compatibility, complexity, trialability, observability, and institution readiness. The study yielded both qualitative and quantitative data, and analysis showed that all six factors influence the adoption of PREMIS in varying degrees. Results of a regression analysis of adoption level on the six factors showed a statistically significant relationship. The R2 value for the model was .528, which means that 52.8% of the variance in PREMIS adoption was explained by a combination of the six factors. Considering the complexity of issue, this study has important implications for future research on preservation metadata and provides recommendations for researchers and stakeholders engaged in metadata standards development efforts.

近年來，資訊科技的進步，改變了人類溝通的方式、知識的管理和傳承、資訊的散播和儲存，對人類社會產生革命性的影響。檔案館開始面對大量的電子文書，並將原有的珍貴館藏轉換為數位物件典藏。然而，看似穩當的數位典藏方式，即使建立了適當的儲存環境，做好各種安全控管，未必能保證數位物件可供長期使用。為了長久保存數位物件並提供使用，除了轉存、轉置、技術模擬等廣受認同的保存方法外，還需要保存後設資料的配合，國際間已有許多相關研究。本研究以RLG、NLA、Cedars、NEDLIB四發展機構所提出的保存後設資料項目為比較對象，得出核心項目，再配合中研院近史所檔案館的需求，建置適用的保存後設資料項目。 經過比較發現，RLG、NLA、Cedars、NEDLIB所提出的保存後設資料項目，因為定位及應用目的不同，在規模、項目及描述層次上有差異，但描述重點仍有某種程度的共識。其中，NLA詳細記載歷次更動相關事項，並針對不同型態數位檔訂立不同的描述項目的做法，值得參考。 考量需求與館藏數位檔特性，中研院近史所檔案館保存後設資料項目雖以四種保存後設資料核心項目為基礎，在建置時仍做了部分修正與更動。(1) 保存後設資料的功能以協助保存決策制定及執行為主，不考慮提供使用的部分，也儘量不與原有後設資料重複；(2) 描述層級訂在系列層級；(3) 更動史項目，綜合NLA及Cedars之優點。限於系統功能限制，保存後設資料仍無法自動產生，也暫時不與數位檔及原有後設資料連結。 根據研究結果，對近史所檔案館及其他典藏機構提出下列建議：(1)制定數位保存政策及計畫；(2) 測試保存方法及保存後設資料項目；(3)留意相關科技及標準的發展趨勢；(4) 保存後設資料應儘量以自動、同步方式產生；(5) 明確定義描述規範。此外，對於數位保存後設資料及保存方法應再深入了解，並尋求跨領域合作機會。

The paper describes a qualitative study of users' attitudes to metadata in relation to their knowledge and how it affects their valuation of digital integrity. Method for data collection is semi-structured interviews and a critical event. The informants were two people who work with IT and two who do not. The theories of undesign, utilitarianism and privacy were chosen to discuss in relation to the result. A thematic analysis method is used to find relationships between attitudes and other interesting themes in the result. These themes, which we have named after the main attitudes of the informants, includes inter alia knowledge, trust, suspicion and positivity. In the discussion chapter, the results are linked with the analysis and answer the research question. The conclusion is that there is no clear correlation between the informants' knowledge and their attitude, knowledge of metadata has little significance for the attitude and the knowledge and attitudes have little effect on the evaluation of integrity among our four informants. / Uppsatsen behandlar en kvalitativ studie av användares attityder till metadata i relation till deras kunskap samt hur det påverkar deras värdering av digital integritet. Metod för datainsamling är semistrukturerade intervjuer samt en kritisk händelse. Informanterna var två personer som är yrkesverksamma inom IT och två som inte är det. Teorierna avdesign, utilitarism samt privatliv valdes ut att diskuteras i relation till resultatet. En tematisk analysmetod används för att hitta samband mellan attityder och andra intressanta teman i resultatet. Dessa teman, som är döpta efter de huvudsakliga attityderna informanterna uppvisat, var bland annat kunskap, tillit, misstänksamhet och positivitet. I diskussionskapitlet sammankopplas resultatet med analysen och besvarar forskningsfrågan. Slutsatsen av denna studie är att vi inte funnit något samband mellan de fyra informanternas kunskap och deras attityd, kunskap om metadata har liten betydelse för attityden och att kunskaperna och attityderna i liten del påverkar värderingen av integritet.

In a variety of text document editing and processing applications, it is necessary to keep track of the revision history of text documents by recording changes and the metadata of those changes (e.g., user names and modification timestamps). The recent Web 2.0 document editing and processing applications, such as real-time collaborative note taking and wikis, require fine-grained shared access to collaborative text documents as well as efficient retrieval of metadata associated with different parts of collaborative text documents. Current revision control techniques only support coarse-grained shared access and are inefficient to retrieve metadata of changes at the sub-document granularity. In this dissertation, we design and implement partial persistent sequences (PPSs) to support real-time collaborations and manage metadata of changes at fine granularities for collaborative text document editing and processing applications. As a persistent data structure, PPSs have two important features. First, items in the data structure are never removed. We maintain necessary timestamp information to keep track of both inserted and deleted items and use the timestamp information to reconstruct the state of a document at any point in time. Second, PPSs create unique, persistent, and ordered identifiers for items of a document at fine granularities (e.g., a word or a sentence). As a result, we are able to support consistent and fine-grained shared access to collaborative text documents by detecting and resolving editing conflicts based on the revision history as well as to efficiently index and retrieve metadata associated with different parts of collaborative text documents. We demonstrate the capabilities of PPSs through two important problems in collaborative text document editing and processing applications: data consistency control and fine-grained document provenance management. The first problem studies how to detect and resolve editing conflicts in collaborative text document editing systems. We approach this problem in two steps. In the first step, we use PPSs to capture data dependencies between different editing operations and define a consistency model more suitable for real-time collaborative editing systems. In the second step, we extend our work to the entire spectrum of collaborations and adapt transactional techniques to build a flexible framework for the development of various collaborative editing systems. The generality of this framework is demonstrated by its capabilities to specify three different types of collaborations as exemplified in the systems of RCS, MediaWiki, and Google Docs respectively. We precisely specify the programming interfaces of this framework and describe a prototype implementation over Oracle Berkeley DB High Availability, a replicated database management engine. The second problem of fine-grained document provenance management studies how to efficiently index and retrieve fine-grained metadata for different parts of collaborative text documents. We use PPSs to design both disk-economic and computation-efficient techniques to index provenance data for millions of Wikipedia articles. Our approach is disk economic because we only save a few full versions of a document and only keep delta changes between those full versions. Our approach is also computation-efficient because we avoid the necessity of parsing the revision history of collaborative documents to retrieve fine-grained metadata. Compared to MediaWiki, the revision control system for Wikipedia, our system uses less than 10% of disk space and achieves at least an order of magnitude speed-up to retrieve fine-grained metadata for documents with thousands of revisions.

Η ραγδαία ανάπτυξη του Παγκόσμιου Ιστού τα τελευταία χρόνια έχει προκαλέσει την αύξηση του εκπαιδευτικού υλικού που είναι διαθέσιμο σε ηλεκτρονική μορφή, με αποτέλεσμα η αναζήτηση και η εύρεση των ψηφιακών εκπαιδευτικών υλικών να γίνεται όλο και πιο δύσκολη. Για αυτό το λόγο τα ψηφιακά εκπαιδευτικά αντικείμενα, ή αλλιώς Μαθησιακά Αντικείμενα (Learning Objects) πρέπει να περιγράφονται με τη χρήση εκπαιδευτικών μεταδεδομένων έτσι ώστε να διευκολύνονται οι λειτουργίες της εύρεσης, ανάκτησης, κατηγοριοποίησης και επαναχρησιμοποίησης των αντικειμένων. Τα τελευταία χρόνια έχουν δημιουργηθεί αρκετά αποθέματα για την αποθήκευση ψηφιακών εκπαιδευτικών αντικειμένων, όπως είναι το DSpace, το EPrints και το Fedora. Τα ψηφιακά αποθέματα κάνουν χρήση μεταδεδομένων για τα ψηφιακά αντικείμενα που αποθηκεύονται στο σύστημά τους. Συχνά όμως παρατηρείται ότι ενώ η κύρια χρήση των αποθεμάτων είναι για εκπαιδευτικούς σκοπούς, δεν δίνεται η δυνατότητα να εμπλουτίζονται τα εκπαιδευτικά αντικείμενα που αποθηκεύονται στα αποθέματα με μεταδεδομένα εκπαιδευτικού τύπου. Κατά συνέπεια, ο κύριος στόχος της διπλωματικής εργασίας είναι να μελετήσει τα διαθέσιμα πρότυπα εκπαιδευτικών μεταδεδομένων και να επεκτείνει τα υπάρχοντα σύνολα μεταδεδομένων των ψηφιακών αποθεμάτων ώστε να συμπεριλαμβάνουν και μεταδεδομένα εκπαιδευτικού σκοπού. Για να επιβεβαιωθούν τα αποτελέσματα της συγκεκριμένης μελέτη έγινε εφαρμογή της σε ένα πραγματικό εκπαιδευτικό απόθεμα που αναπτύχθηκε στα πλαίσια του ΕΠΕΑΕΚ ΙΙ για το Πανεπιστήμιο Πατρών. Βασικό χαρακτηριστικό των εκπαιδευτικών αποθεμάτων είναι και η διαλειτουργικότητα με άλλα συστήματα. Η διαλειτουργικότητα εξασφαλίζει τη συνεργασία του συστήματος με άλλα αποθέματα επιτρέποντας τη συγκομιδή και αξιοποίηση των ψηφιακών αντικειμένων και από άλλα αποθέματα. Για το λόγο αυτό μελετάται το πώς μπορεί να επιτευχθεί η διαλειτουργικότητα ενός συστήματος ώστε να αξιοποιούνται και τα εκπαιδευτικά μεταδεδομένα του αποθέματος, μέσω της υπηρεσίας ΟΑΙ-PMH, που υποστηρίζεται από τα περισσότερα αποθέματα, αλλά και μέσω της καινούριας υπηρεσίας OAI-ORE. Η υλοποίηση της διαλειτουργικότητας στα πλαίσια της συγκεκριμένης εργασίας επικεντρώνεται στο σύστημα DSpace. Ο Σημαντικός Ιστός (Semantic Web) αποτελεί την εξέλιξη του Παγκόσμιου Ιστού. Στον Σημαντικό Ιστό οι πληροφορίες περιγράφονται από δεδομένα αποκτώντας συγκεκριμένη σημασία και δίνοντας έτσι τη δυνατότητα στις μηχανές να επεξεργαστούν δεδομένα που μέχρι σήμερα ήταν κατανοητά μόνο από τους ανθρώπους. Έτσι, γίνεται μελέτη ώστε να επιτευχθεί η δυνατότητα σημασιακής διαλειτουργικότητας στα αποθέματα και συγκεκριμένα στο DSpace. Με τον τρόπο αυτό γίνεται δυνατή η συνδιαλλαγή και διαπραγμάτευση πληροφοριών μεταξύ συστημάτων, οι οποίες, ενώ μπορεί να είναι κατά βάση ετερογενείς, προερχόμενες από πολλαπλές πηγές και αδόμητες σημασιακά, μπορούν να συσχετίζονται και, βάσει συμπερασμών, να συνδυάζονται κατάλληλα με στόχο την ανακάλυψη νέας γνώσης. / The rapid growth of World Wide Web in the last years has led to an increase of the educational material that is available in digital way. As a result of this, searching and discovering of digital educational material is becoming more and more difficult. For this reason, digital education objects, or Learning Objects, have to be described using education metadata in order to facilitate searching, retrieval, classification and reuse of these objects. In the recent years, a lot of repositories have been built to store digital educational objects, like DSpace, EPrints and Fedora. Digital repositories make use of metadata to describe digital objects that are stored in their system. But we can note that although the main use of these repository systems is for educational purposes, we do not have the ability to enrich learning objects that are stored in these systems with educational metadata. Therefore, the main purpose of this thesis is to study the available educational metadata standards and to extend the available metadata sets of digital repositories in order to include and support metadata for education purposes. A main feature of most educational repositories is interoperability with other systems. Interoperability assures the cooperation of one repository with others by allowing the harvesting and using of digital objects stored in one place by other systems and services. For this reason, it is studied how educational metadata can be incorporated in a repository’s interoperability services, and mainly in the OAI-PMH service, which is supported by most repositories, but also in a new service named OAI-ORE. The implementation of these interoperability services is focused on the DSpace system. Finally, Semantic Web is the evolution of World Wide Web. In Semantic Web information is described by data, so this information gains meaning which gives the ability to machines to process this information which till now was meaningful only to humans. So, it is also studied how semantic interoperability can be achieved between repositories and specifically between repositories based on DSpace. This will give the ability to exchange information between systems. Although this information may come from different and heterogeneous sources, and although this information may be semantically unstructured, it can be associated and combined in order to discover new knowledge.

In this context, the aim of the research was to verify to what extent standards or metadata schemas for digital preservation have been discussed by the field of Information Science and related fields (Archival Science, Library Science, Museology etc.), pointing out how these schemas could meet the structuring demands of institutional repositories more adequately for the preservation of digital documents. In terms of method, an exploratory study, based on bibliographic and documentary research relating to standards or metadata schemes used in the scope of digital preservation, was conducted. A comparative analysis of standards or metadata schemes identified in the literature was carried out, based on core metadata elements considered for digital preservation. Regarding the results, a theoretical technical framework is presented, that seeks to systematize standards or metadata schemes applicable to digital preservation, such as DC, MODS, EAD, ANSI/NISO Z39.87 or MIX, METS and PREMIS and at the same time, that may be relevant for modeling digital institutional repositories. It was found that the guarantee of long-term digital preservation will only be possible with the effective implementation of standards and metadata schemas, because it is they that define the description, representation, consistency and persistence of the digital object/resource in the information environment, as well as determining interoperability between systems. There is no way to say which of the existing metadata schema fully ensures digital preservation but that it is indeed possible to have different standards working together in order to complement the effective registration of the information required in managing preservation and usable access over time of digital objects/resources. / Com o expressivo aumento na produção e aquisição de conteúdos digitais, ações de recuperação e de preservação de dados a longo prazo estão sendo criadas e estudadas defronte às mudanças tecnológicas de armazenamento e de acesso aos recursos informacionais. Nesse contexto, objetiva-se verificar em que medida padrões ou esquemas de metadados no âmbito da preservação digital têm sido discutidos pelo campo da Ciência da Informação e áreas afins (Arquivologia, Biblioteconomia, Museologia etc.), apontando de que maneira estes esquemas poderiam atender as demandas de estruturação de repositórios institucionais de maneira mais adequada para a preservação de documentos digitais. Como metodologia destaca-se a realização de um estudo exploratório, pautado em pesquisa bibliográfica e documental referente aos padrões ou esquemas de metadados utilizados no escopo da preservação digital. Aplicou-se a análise comparativa dos padrões ou esquemas de metadados identificados na literatura, baseada em elementos de metadados considerados essenciais para a preservação digital. Como resultado apresenta-se um quadro referencial teórico, técnico e sistematizado de padrões ou esquemas de metadados aplicáveis à preservação digital, tais como DC, MODS, EAD, ANSI/NISO Z39.87 ou MIX, METS e PREMIS e, ao mesmo tempo, que podem ser relevantes para a modelagem de repositórios institucionais digitais. Constatou-se que a garantia de preservação digital a longo prazo só será possível com a adoção efetiva de padrões ou esquemas de metadados, pois são eles que definirão a descrição, a representação, a consistência e a persistência do recurso/objeto digital no ambiente informacional, além de determinar a interoperabilidade entre sistemas. Não há como afirmar qual é o único esquema de metadados existente que assegure totalmente a preservação digital e, sim, que diferentes padrões podem trabalhar juntos, de modo a se auto complementarem para o registro eficaz das informações requeridas na gestão da preservação e do acesso utilizável ao longo do tempo de objetos/recursos digitais.

nÃo hà / A pesquisa objetiva definir estratÃgias de conversÃo de registros bibliogrÃficos do formato MARC 21 para os esquemas de metadados MARCXML, Metadata Authority Description Schema (MADS) e Metadata Object Description Schema (MODS), por meio dos cabeÃalhos de autoridade de nomes e assuntos como categorias de anÃlise. Procedeu-se ao mapeamento dos subcampos com seus respectivos valores e o posterior cotejamento com as tags dos esquemas de metadados alvo da conversÃo. A pesquisa de carÃter exploratÃria e descritiva propiciada por levantamentos bibliogrÃficos e documentais adota a observaÃÃo sistemÃtica como tÃcnica viabilizadora da etapa empÃrica. Aborda o modelo entidade-relacionamento adotado pelosFunctional Requirements for Bibliographic Records (FRBR) como ferramenta para modelar o relacionamento entre os atributos dos metadados em estudo e o formato MARC com as prescriÃÃes dos Functional Requirements for Authority Data (FRAD)para os dados de autoridade de nome pessoal e os Functional Requirements for Subject Authority Data (FRSAD) para os dados de autoridade de assuntos tÃpicos. A anÃlise preliminar demonstrou que a flexibilidade dos esquemas permite tratar redundÃncias e ambivalÃncias na representaÃÃo de nomes pessoais e seus atributos.Permite, ainda,a abordagem por meio de remissivas e qualificadores apropriados com Ãnfase nos aspectos ligados a sinonÃmia e polissemia dos cabeÃalhos de assuntos. Analisa a flexibilidade notacional de esquemas correlatos como o Metadata Encoding and Transmission Standard (METS) na esteira da perspectiva de recursos de informaÃÃo interoperÃveis. Insere o vocabulÃrio Dublin Core na discussÃo e codificaÃÃo de metadados descritivos, o que possibilitou mapear limites e possibilidades deste vocabulÃrio no contexto bibliogrÃfico. Os resultados das conversÃes realizadas ilustraram o papel estratÃgico do modelo entidade-relacionamento como paradigma conceitual adotado pelos FRBR e, subsidiariamente pelos FRAD e FRSAD, na conduÃÃo das etapas de mapeamento e codificaÃÃo dos dados de autoridade de nome pessoal e assunto tÃpico de MARC para MADS e MODS. Foi observado que todos os campos e subcampos MARC analisados,alÃm de encontrarem seus equivalentes nos esquemas XML correspondentes, sÃo acrescidos de atributos relacionais que demonstraram efetividade nos vÃnculos que associam autores a papÃis assumidos nos recursos. Conclui que as estratÃgias de conversÃo aplicadas extraem o valor semÃntico do paradigma relacional preconizado pelos FRBR como elemento chave para alcance de expressividade, coerÃncia interna e sofisticaÃÃo das relaÃÃes sintÃticas e semÃnticas tÃo caras à efetividade dos catÃlogos. Sugere, a partir da literatura consultada e dos resultados verificados na etapa empÃrica, pesquisas que visem contemplar estratÃgicas de conversÃo de metadados com Ãnfase nos grupos 2 e 3 dos FRBR. / The objective of this research is to define strategies for converting bibliographic records from MARC 21 format to MARCXML, Metadata Authority Description Schema (MADS) and Metadata Object Description Schema (MODS) metadata schemas, through name and subject authority as analysis categories. The mapping of the subfields with their respective values and the subsequent collation with the tags of the metadata schemes target of the conversion were done. The exploratory and descriptive research provided by bibliographical and documentary surveys adopts systematic observation as a technique that enables the empirical stage. It ad-dresses the entity-relationship model adopted by the Functional Requirements for Biblio-graphic Records (FRBR) as a tool to model the relationship between the attributes of the metadata under study and the MARC format with the requirements of Functional Require-ments for AuthorityDescription (FRAD) and the Functional Requirements for Subject Authority Data (FRSAD) for the topics subject authority data. The preliminary analysis showed that the flexibility of the schemas allows to treat redundancies and ambivalences in the representation of personal names and their attributes. It also allows the approach through appropriate refer-ences and qualifiers with emphasis on aspects related to synonymy and polysemy of subject headings. It analyzes the notational flexibility of related schemas such as Metadata Encoding and Transmission Standard (METS) in the wake of the perspective of interoperable infor-mation resources. It inserts the Dublin Core vocabulary into the discussion and coding of de-scriptive metadata, which made it possible to map the limits and possibilities of this vocabu-lary in the bibliographic context. The results of the conversions carried out illustrated the stra-tegic role of the entity-relationship model as a conceptual paradigm adopted by the FRBR and, in a subsidiary way, by the FRAD and FRSAD, in the process of mapping and coding the personal name and subject matter authority data from MARC to MADS and MODS. It was observed that all the analyzed MARC fields and subfields, besides finding their equiva-lents in the corresponding XML schemas, are added with relational attributes that demon-strated effectiveness in the links that associate authors to roles assumed in the resources. It concludes that the applied conversion strategies extract the semantic value of the relational paradigm advocated by the FRBR as a key element for the reach of expressiveness, internal coherence and sophistication of the syntactic and semantic relations so dear to the effectiveness of the catalogs. It suggests, from the literature consulted and the results verified in the empiri-cal stage, researches that aim to contemplate strategies of metadata conversion with emphasis in groups 2 and 3 of FRBR.

More and more print jobs are delivered from customer to printer digitally over the Internet. Although Internet-based job delivery can be highly efficient, companies in the graphic arts and printing industry often suffer unnecessary costs related to this type of inflow of print jobs to their production workflows. One of the reasons for this is the lack of a well-defined infrastructure for delivering print jobs digitally over the Internet. This thesis presents INFLOW - a prototype for a print job delivery system for the graphic arts and printing industry. INFLOW is a web-based job delivery system that is hosted on an Internet-connected server by the organization receiving the print jobs. Focus has been on creating a system that is easy to use, highly customizable, secure, and easy to integrate with existing and future systems from third-party vendors. INFLOW has been implemented using open standards, such as XML and JDF (Job Definition Format). The requirements for ease-of-use, high customizability and security are met by choosing a web-based architecture. The client side is implemented using standard web technologies such as HTML, CSS and JavaScript while the serverside is based on J2EE, Java Servlets and Java Server Pages (JSP). Using a web browser as a job delivery client provides a highly customizable user interface and built in support for encrypted file transfers using HTTPS (HTTP over SSL). Process automation and easy integration with other print production systems is facilitated with CIP4’s JDF (Job Definition Format). INFLOW also supports"hot folder workflows"for integration with older preflight software and other hot folder-based software common in prepress workflows.

Contrairement à l'opinion dominante, les nouvelles technologies n'ont pas toujours un impact positif sur la qualité des métadonnées dans le secteur culturel. Après dix ans d'expérience avec les projets de numérisation dans nos musées, bibliothèques et archives, une réflexion critique se montre plus que jamais nécessaire pour évaluer à quelles conditions ce genre de projets d'informatisation peuvent offrir une valeur ajoutée pour la documentation de notre patrimoine culturel. Cette réflexion se base, entre autres, sur un ensemble de case studies représentatifs dans un contexte international. A cette fin, nous présenterons et définirons un cadre méthodologique et conceptuel original concernant l'impact des technologies sur la qualité des métadonnées. Sur cette base, nous proposons et expérimentons trois approches opérationnelles novatrices en vue d'améliorer la qualité des systèmes d'information déployés dans le secteur culturel. / Doctorat en Information et communication / info:eu-repo/semantics/nonPublished
