Research Objects

In the domain of eScience, investigations are increasingly collaborative. Most scientific and engineering domains benefit from building on top of the outputs of other research: By sharing information to reason over and data to incorporate in the modelling task at hand. This raises the need to provide means for preserving and sharing entire eScience workflows and processes for later reuse. It is required to define which information is to be collected, create means to preserve it and approaches to enable and validate the re-execution of a preserved process. This includes and goes beyond preserving the data used in the experiments, as the process underlying its creation and use is essential. This tutorial thus provides an introduction to the problem domain and discusses solutions for the curation of eScience processes

Παραδοτέο Π.2.3: Μηχανισμοί επερώτησης και ανάκτησης πληροφορίας

Το παρόν Παραδοτέο Π.2.3 περιλαμβάνει τα αποτελέσματα της υποδράσης ΥΔ2.3. Στην ενότητα 1 παρουσιάζουμε το γενικότερο πλαίσιο του προβλήματος. Στην ενότητα 2 προτείνεται ένα framework για την απάντηση ερωτημάτων συντομότερης διαδρομής σε γράφους κοινωνικών δικτύων με τη χρήση σχεσιακού συστήματος βάσεων δεδομένων. Στην ενότητα 3 παρουσιάζεται ένα εργαλείο για την ιεραρχική χαρτογράφηση και οπτική εξερεύνηση διασυνδεδεμένων δεδομένων, ενώ στην ενότητα 4 ερευνάται η αποδοτική πλοήγηση και οπτικοποίηση πολύ μεγάλων RDF γράφων. Στην ενότητα 5 παρουσιάζεται μια πρώτη προσέγγιση στο πρόβλημα της διαφοροποίησης αποτελεσμάτων αναζήτησης σε RDF δεδομένα. Στις ενότητες 6 και 7 αναφερόμαστε σε αποτελέσματα σχετικά με την αναζήτηση σε RDF δεδομένα

Organizing videogame metadata in CollectiveAccess

Local institutions need to organize information sets with complex information and attributes. Whether or not open source software has the ability to adequately provide a robust yet easy-to-use system for such institutions is a question raised frequently. To explore that question, a metadata schema created by the GAme MEtadata Research Group (GAMER) at the University of Washington was implemented in CollectiveAccess (CA), an open source cataloging software used by many organizations to manage digital collections, as a case study. As an organizational system, CA is appealing because it enables users to create metadata schema with relative ease. However, during implementation, issues emerged related to its potential as a long-term solution, including ease-of-use for both administrators and end-users. This poster explains and expands upon the issues encountered during the implementation process, focusing on how they might be resolved, and what the implications are for designing similar applications in the future

Kurator danych cyfrowych – nowe stanowisko w bibliotece naukowej

In the article the authors have pointed out the need to establish institutional centers for storage and digital data curation.  The amount of data increases with the development of science, therefore there is a need to protect both raw data resulting from big and small scientific research, as well as resources from repositories and digital libraries. The authors discuss the concepts of digital curation and data management by digital curators coming from the library world.W artykule wskazano na potrzebę powołania instytucjonalnych systemów umożliwiających centralne składowanie i ochronę danych cyfrowych. Liczba danych rośnie wraz z rozwojem nauki. Należy chronić zarówno surowe dane, będące wynikiem badań naukowych w ramach wielkiej i małej nauki, jak i zasoby repozytoriów publikacji i bibliotek cyfrowych. Przedstawiono koncepcję ochrony danych cyfrowych i ich zarządzania przez kuratorów danych cyfrowych, wyłonionych ze środowiska bibliotekarskiego

Die Hard: The Impossible, Absolutely Essential Task of Saving the Web for Scholars

The web is fragile and littered with broken links. This poses a problem for the scholarly record and one’s own academic history. In this presentation given at the Association of College & Research Libraries – Eastern New York chapter conference, I review the stats on link rot and reference rot, and I give a brief overview of web archiving and its challenges. I review some web archiving tools: the Internet Archive, Perma.cc, WebRecorder, and GitHub. I advise creators of web projects to design their websites to be accessible and archivable, and to think about preservation (afterlife) of their projects from the start of the planning stages. I advise librarians and archivists to become familiar with web archiving tools and archivability/accessibility practices so that they, in turn, can advise web project creators
