The new digital technologies made real the convergence of ideals and tools, but with it brought troubles and questions to solve. The inovation created digital libraries, repositories of information now available in any part of the world, intricate search engines filled with complex metadata all of it bringing cooperation to a new level. Image repositories have particular dificulties from other type of archives and are relegated to a secundary role or even forgotten over text digital archives, this needs to be changed. I go through all the stages, from metadata methods, to the questions of acess, funding, web 2.0 Mashing up for tool improvement and the dificult copyright issues; in the intent of providing enough information and methodology to change even a little bit the present state of digital image repositories. The practical example used is a image repository created for the University of Coimbra that gains from the expertise of database software and the methodology, with the objective of showing how to put all the methods into practice in a good way, and explain cliffs and errors that can be avoided.; Dissertação de mestrado em Património Europeu, Multimédia e Sociedade da Informação, (Bibliotecas Digitais e Repositórios de Imagem) apresentada à Faculdade de Letras da Universidade de Coimbra

Atualmente, com os avanços tecnológicos, há disponível uma quantidade grande e heterogênea de dados multimídia. Estes dados podem ser provenientes de fontes diversificadas, desempenhando um papel fundamental em sistemas de informação, tais como repositórios de Bibliotecas Digitais. Com o objetivo de reutilizar, integrar, agregar e unificar diferentes recursos sob o mesmo conceito, objetos complexos surgiram para facilitar a abstração de agregações, utilizando componentes de diferentes domínios, e unificando-os sob o mesmo conceito. Em especial, os objetos complexos de imagens são um exemplo representativo de fonte de dados que geralmente é integrada com componentes heterogêneos, tais como metadados, links e softwares de manipulação de imagem. A busca de imagens é um serviço importante, amplamente explorado em sistemas de Biblioteca Digital. A recuperação de imagens por conteúdo aborda a busca automática de imagens, considerando propriedades visuais (como textura e cor). Este trabalho trata de três aspectos relacionados a objetos complexos: (i) a formalização de conceitos; (ii) a comparação de tecnologias relacionadas; e (iii) a especificação e a implementação de um protótipo, que encapsula e publica objetos complexos de imagens manipulados em sistemas de busca de imagens por conteúdo. A infraestrutura proposta baseia-se em uma estrutura de componentização específica - Digital Content Component (DCC) - para encapsular o processo de busca de imagens por conteúdo e o objeto complexo de imagem.

Esse trabalho propõe-se a estudar os sites de arquivos públicos, em seus diálogos com práticas de memória, de ensino de História e de educação das sensibilidades na contemporaneidade. Para tal, elege como fontes os próprios sites de arquivos, bem como a literatura recente produzida por arquivistas e pesquisadores de ensino de História, referente às relações entre arquivos e educação. Esses dois conjuntos de fontes, ao serem entrecruzados, fazem emergir um uma rede de discursos e práticas que se articulam, internacionalmente, como tendências prevalecentes, na literatura e nas práticas recentes dessa área em que se configuram as aproximações entre arquivos e educação. O referencial bibliográfico, no trabalho de articular a multidisciplinaridade dos campos estudados às possibilidades de diálogo dos autores em seus enfoques teóricos e metodológicos, foi eleito tendo em vista entrecruzar os diferentes autores das áreas da arquivística, da história cultural e da educação, em algumas de suas aproximações e confrontos, a partir de questões elaboradas nos sucessivos diálogos com as fontes. As relações entre arquivos e educação são pensadas a partir da ótica da educação patrimonial, do ensino de História...

This paper describes the planning stages of the creation of a national level federation of archives. The Open Archives Initiative Protocol for Metadata Harvesting will be used for collecting metadata being produced by local archives using any compliant records management software. The first stage of implementation will harvest metadata produced with the DigitArq [1-3] platform in a pilot group of Portuguese Regional Archives. DigitArq relies on Encoded Archival Description (EAD) metadata to describe its collections. However, the overwhelming flexibility and complexity of EAD make the harvesting operation more complex than usual. This paper addresses possible ways of exchanging EAD records using OAI-PMH as the basis for a central repository of metadata that will enable the creation of advanced information services at the national level.

The MIT Libraries, the San Diego Supercomputer Center, and the University of California San Diego Libraries are conducting the PLEDGE Project to determine the set of policies that affect operational digital preservation archives and to develop standardized means of recording and enforcing them using rules engines. This has the potential to allow for automated assessment of "trustworthiness" of digital preservation archives. We are also evaluating the completeness of other efforts to define policies for digital preservation such as the RLG/NARA Trusted Digital Repository checklist and the PREMIS metadata schema. We present our results to date.; National Archives and Records Administration (US) under NSF cooperative agreement 0523307 through a supplement to SCI 0438741 and the NSF grant ITR 0427196.

The RLG/NARA trusted digital repository (TDR) certification checklist defines a set of assessment criteria for preservation environments. The criteria can be mapped into data management policies that define how a digital preservation environment is operated. We explore how the enforcement of these management policies can be automated through their characterization as rules that control preservation services. By integrating a rule-based data management system with the DSpace digital archive system, we expect to demonstrate automated audits of the TDR checklist for a defined set of local policies. The system is sufficiently general that one can also demonstrate the completeness and self-consistency of preservation environments. This is the concept that all required preservation metadata are controlled by management policies, and that for each management policy the required preservation metadata are preserved.; National Archives and Records Administration under NSF cooperative agreement 0523307 through a supplement to SCI 0438741, "Cyberinfrastructure; From Vision to Reality"

The group behind the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) has recently released a beta specification for a new protocol, entitled Open Archives Initiative Object Reuse and Exchange (OAI-ORE). OAI-ORE "defines standards for the description and exchange of aggregations of Web resources," a need commonly faced by digital libraries. This presentation will provide an introduction to the OAI-ORE data model and serializations of OAI-ORE "resource maps" in Atom and RDF. It will also discuss the movement towards data sharing by digital libraries using mechanisms native to the Web rather than in library-centric, high-value and low adoption protocols.

The Victorian Women Writers Project began in 1995 at Indiana University under the editorial leadership of Perry Willett and was celebrated early on for exposing lesser-known British women writers of the 19th century. The VWWP's original focus on poetry was meant to complement The English Poetry Full-Text Database, but soon Willett acknowledged the variety of genres in which women of that period were writing novels, children's books, political pamphlets, religious tracts. The collection expanded to include genres beyond poetry, and continued active development from 1995 until roughly 2000 at which point the corpus reached approximately two hundred texts. These nearly two hundred texts comprise only a small fraction of Victorian women's writing. Encouraged by renewed interest among Indiana University's English faculty and graduate students, the Indiana University Libraries and the English Department are exploring ways to reinvigorate the project, and in turn, cultivate a sensibility in digital humanities methodologies and theories. Through our newly offered graduate English course (L501, Digital Humanities Practicum), an eager and curious group of students learned not only encoding skills but also began to develop the collaborative practices pervasive in the digital humanities.

A recording is not available for this presentation.; Institutional repositories have been created primarily to disseminate and preserve faculty research and the scholarly output of academic departments, institutes, centers and research units. IU's Archives of Institutional Memory (AIM) was created to collect, preserve and make available those records that do not fit neatly into the typical DSpace environment, namely the official records of the University, such policy documents, annuals reports, and IU Bulletins. At this presentation the University Archivist will review 1) the mission and objectives of AIM; 2) how AIM fits into the larger IU strategy for disseminating and preserving mission critical records; 3) the appraisal process for determining what goes into AIM; and 4) the preservation strategies that are being implemented, which will include a review of PDF/A as a preservation format.

The MPPDA Digital Archives consist of a database of the extant records of the General Correspondence files of the Motion Picture Producers and Distributors of America, Inc., covering the period from 1922 to 1939. Established in 1922, the MPPDA was the trade association for the motion picture industry, and included all the major companies producing and distributing motion pictures in the United States in its membership. The association was popularly known as the Hays Office, after its first President, Will H. Hays, who remained in office until 1945. Hays was a leading Republican party politician, who resigned from President Warren Harding's Cabinet to take up the MPPDA position. After Hays' retirement, the association was renamed the Motion Picture Association of America.; Australian Academy of the Humanities; the ANU College of Arts and Social Sciences

The creation of open archives i.e. archives where access is regulated by open licensing models (content, source, data), should be seen as part of a broader socio-economic phenomenon that finds legal expression in specific organizational and technical formats.This paper examines the origins and main characteristics of the open archives phenomenon. We investigate the extent to which different models of production of economic or social value can be expressed in different forms of licensing in the context of open archives. Through this process, we assess the extent to which the digital archive is moving towards providing access that is deeper (meaning, that offers more access rights) and wider (in the sense that most of the information given is in open content licensing) or face a gradual stratification and polarization of the content. Such stratification entails the emergence of two types of content: content to which access is extremely limited and content to which access remains completely open. This differentiation between classes of content is the result of multiple factors: from purely legislative, administrative and contractual restrictions (e.g. data protection and confidentiality restrictions) to information economics (e.g. peer production) or social (minimum universal access). We claim that with respect to the access management model...

The transition from analogue to digital archives and the recent explosion of online content offers researchers novel ways of engaging with data. The crucial question for ensuring a balance between the supply and demand-side of data, is whether this trend connects to existing scholarly practices and to the average search skills of researchers. To gain insight into this process we conducted a survey among nearly three hundred (N= 288) humanities scholars in the Netherlands and Belgium with the aim of finding answers to the following questions: 1) To what extent are digital databases and archives used? 2) What are the preferences in search functionalities 3) Are there differences in search strategies between novices and experts of information retrieval? Our results show that while scholars actively engage in research online they mainly search for text and images. General search systems such as Google and JSTOR are predominant, while large-scale collections such as Europeana are rarely consulted. Searching with keywords is the dominant search strategy and advanced search options are rarely used. When comparing novice and more experienced searchers, the first tend to have a more narrow selection of search engines, and mostly use keywords. Our overall findings indicate that Google is the key player among available search engines. This dominant use illustrates the paradoxical attitude of scholars toward Google: while provenance and context are deemed key academic requirements...

The next-generation astronomy digital archives will cover most of the universe at fine resolution in many wave-lengths, from X-rays to ultraviolet, optical, and infrared. The archives will be stored at diverse geographical locations. One of the first of these projects, the Sloan Digital Sky Survey (SDSS) will create a 5-wavelength catalog over 10,000 square degrees of the sky (see http://www.sdss.org/). The 200 million objects in the multi-terabyte database will have mostly numerical attributes, defining a space of 100+ dimensions. Points in this space have highly correlated distributions. The archive will enable astronomers to explore the data interactively. Data access will be aided by a multidimensional spatial index and other indices. The data will be partitioned in many ways. Small tag objects consisting of the most popular attributes speed up frequent searches. Splitting the data among multiple servers enables parallel, scalable I/O and applies parallel processing to the data. Hashing techniques allow efficient clustering and pair-wise comparison algorithms that parallelize nicely. Randomly sampled subsets allow debugging otherwise large queries at the desktop. Central servers will operate a data pump that supports sweeping searches that touch most of the data. The anticipated queries require special operators related to angular distances and complex similarity tests of object properties...

This is the author accepted manuscript. The final version is available from Taylor & Francis via http://dx.doi.org/10.1080/09647775.2015.1042515; In this paper, we present two experiments designed to compare 2D digital pictures and 3D digital replicas of artefacts, to understand how differently these media facilitate the perception and understanding of our past. Archaeologists and museum experts have commonly used 2D digital pictures to preserve and study artefacts. Recently these scholars have also started to use 3D digital archives for their studies. Yet we still need to determine how these two formats (2D vs 3D) affect the perception of our past. Results to our experiments point to 3D digital replicas of artifacts as more effective means to digitally preserve tangible cultural heritage, since 3D multi-visualization augments the perception of physical characteristics of the artifacts allowing a more embodied experience with these objects. Our experiments also suggest that multi-visualization (i.e., point-cloud, mesh, and color information) helps the viewers to overcome their personal conceptualization of specific objects.

In support of research projects both within the Munsell Color Science Laboratory and outside which rely on having full knowledge of the spectral makeup of scenes, a number of methods for capturing spectral images are being explored. This project is named Lippmann2000 in honor of Gabriel Lippmann who in 1891 devised a method to perfectly reconstruct the spectral content of real world scenes. In spite of Lippmann’s invention, a more primitive three-channel model, first demonstrated by James Clerk Maxwell 30 years prior, has dominated the color imaging field. The Maxwellian model, universal in today’s silver halide and electronic color image capture systems, relies on the metameric properties of the human visual system to simulate the appearance of an original color. It has been recognized by those in the forefront of imaging research that the capture of full spectral data holds advantage over traditional three-channel methods. This paper describes our efforts to-date to build our database of spectral images.; "Lippmann 2000: a spectral image database under construction," Presented at the International Symposium on Multispectral Imaging and Color Reproduction for Digital Archives.
