Publikace Otevřený přístup Blend and deblend Linked open data in a Consortium(2018) Pallarès, JordiWorking in a Consortium give us the perspective to see the benefits of blending ideas to create a applications from a central data/point. In some cases we found the Institution want to deblend or „not blend“ with the consortium and prefer or they see more benefits to made his own aplication. We explain our experience in the Consortium blending and not blending desicions and explain two projects in linked open data to show examples of this two ways. One project We blend all the authorities and in other we not blend in the case of Thesaurus of the University of Barcelona using Skos format.Publikace Otevřený přístup ELAG Community(2018) Koster, Lukas; Harlow, ChristinaLightning Talks (June 8), video recording is available at: http://repozitar.techlib.cz/record/1275Publikace Otevřený přístup A Lightning Talk on Manuscripts and IIIF(2018) Seige, LeanderLightning Talks (June 8), video recording is available at: http://repozitar.techlib.cz/record/1275Publikace Otevřený přístup From Hydras to TACOs: Evolving the Stanford Digital Repository(2018) Harlow, Christina; Fahy, ErinStanford University Library has a robust digital library system called the Stanford Digital Repository. This repository holds a little under 500 TB of materials in preservation and online for researchers, capture of scholarly output, and digitized cultural heritage materials. These materials are managed across 90+ codebases serving a variety of functions from self-deposit web applications, to a nearly 10 year old parallel processing framework, to a digital repository assets publication mechanism leading into our Blacklight, Spotlight, and Geoblacklight applications – among other services and needs. At the core of this system is a Fedora 3 store. With Fedora 3 now end-of-lifed, and our system suffering from limited to no horizontal scalability options, we’re revisiting our system and architecture. We are writing it from the start with a goal to have data-forward, distributed microservices and some event-driven processing components. TACO, our new core management API, is the heart of this new architecture, and is currently being developed as a prototype. This talk will walk through the process of analysing our current system via a dataflows analysis; designing a new architecture for our digital library with a wide ranging set of requirements and users; prototyping a core component of our new architecture to be horizontally scalable as well as data & specification driven; then planning how to create ‘seams’ in our current system to migrate towards our new system in an evolutionary fashion instead of a turn-key migration.Publikace Otevřený přístup Largest Koha Installation of 1,130 Public Libraries in Turkey(2018) Yazicioglu, MenguThe public libraries in Turkey belongs to Ministry of Culture and every city in Turkey has many public libraries, more than 1,140 libraries now. In 2014, they decided to migrate from a local system to Koha and after first period, we widely start to support public libraries in a centeralized system with Koha. Many new modules were added to Koha system and we also migrate to 3.20.x version later. More than 5.000.000 duplicate bibliographic records were merged in that period. In this presentation, we’d like to share all installation process of a largest centeralized system by a free open source library system Koha.Publikace Otevřený přístup In Out, In Out, And Shake It All About: A Moving Story of Data(2018) Stevenson, JaneThe Archives Hub blends data. We bring together descriptions of archives, archival resources and repositories in a way that enables us to present an effective and valuable service through our website. We spent two years creating an entirely new system that was built upon the principle of bringing in data from different sources and providing that data for different purposes. I would like to give some insights from our experience of doing this, and consider whether we have created something innovative and with inherent potential for future development. I will talk about the architecture that we wanted to create, the workflow that we believed to be essential to our aims, and the challenges that we faced in being able to create a blend of data that could be successfully deblended in different ways. It required a great deal of thought and planning in terms of what we wanted to achieve, how we should process the data to fulfil those aims, and how we would work with data contributors, who were essential to our success. Over a year after going live with the new service, have we achieved our aim of more consistent, standardised data, and have we provided the realistic potential for the data to be re-used? I will give examples of where I think we have fulfilled our aims and where we still have issues. I will argue that the ability to blend/deblend relies upon systems and technology, but it also relies upon people and their habits, expectations, understanding and ambitions.Publikace Otevřený přístup From XML to MARC: RDF Behind the Scenes(2018) Nicolas, YannWe collect heterogeneous metadata packages from various publishers. Although all of them are in XML, they vary a lot in terms of vocabulary, structure, granularity, precision, and accuracy. It is quite a challenge to cope with this jungle and recycling it to meet the needs of the Sudoc, the French academic union cataloguing system. How to integrate and enrich these metadata? How to integrate them in order to process them in a regular way, not through ad hoc processes? How to integrate them with specific or generic controlled vocabularies ? How to enrich them with author identifiers, for instance? RDF looks like the ideal solution for integration and enrichment. Metadata are stored in the Virtuoso RDF database and processed through a workflow steered by the Oracle DB. We will illustrate this generic solution with Oxford UP metadata: ONIX records for printed books and KBART package description for ebooks. So. A relational database as glue and pipeline engine… RDF as internal model… MARC as output …. Quite weird… Was this abstract written by an ELAG-specific random text generator?Publikace Otevřený přístup Rethinking the IT system architecture(2018-06) Berthold, HenrikeThe Saxon State and University Library in Dresden (SLUB) is the university library of Dresden University of Technology (TUD) and the state library of Saxony with a history starting in1556. Because of these two roles, it is an independent research institution with a range of tasks. They include services for TUD, such as an open access repository, support for specific research communities, collection and long-term preservation of digital documents published in Saxony, and internal production and processing workflows. In the presentation I will present the target IT infrastructure, the background of some design decisions, the challenges we have identified and the projects we currently run to develop our infrastructure towards the target one.Publikace Otevřený přístup The ARCLib Project: an Open-Source Solution for Long-Term Preservation(2018-06-04) Růžička, MichalThe talk informs about the Czech ARCLib project. One of the main goals of the project is the development of an open-source solution for a bit-level and logical preservation of digital documents, respecting the national and international standards as well as the needs of all types of libraries in the Czech Republic. The mission of the ARCLib project lies, among others, in creating a solution that will allow institutions to implement all of the OAIS functional modules and entities, considering institutions’ information model. The architecture is planned as open and modular and the final product will be able to ingest, validate and store data from a majority of software products used for creating, disseminating and archiving libraries’ digital and digitised data in the Czech Republic.Publikace Otevřený přístup Fundamentals(2018-06-05) Koch, OndřejLet’s take a look at the IT infrastructure of this library and talk about IT architecture in general with practical examples right here where we stand (or sit). How do we do things? How do we solve security issues? What about identities? Do we need a cloud and what kind of cloud? How do we manage our network and computing resources? Let’s look at those „simple and boring“ things like storage, compute and network, let’s talk about digital signage and AV stuff in here. Why? Because it matters, these are the fundamentals of every library as a building, as a place to study and as a place where data is properly and logically stored so that everyone can get meaningful information out of it.Publikace Otevřený přístup The Delicate Dance of Decentralization and Aggregation: keynote speech(2018-06-05) Verborgh, RubenRuben Verborgh is a professor of Semantic Web technology at Ghent University – imec and a research affiliate at the Decentralized Information Group at MIT. He aims to build a more intelligent generation of clients for a decentralized Web at the intersection of Linked Data and hypermedia-driven Web APIs. Through the creation of Linked Data Fragments, he introduced a new paradigm for query execution at Web-scale. He has co-authored two books on Linked Data, and contributed to more than 200 publications for international conferences and journals on Web-related topics.Publikace Otevřený přístup Moving from Find & Get and Towards Use & Understanding(2018-06-05) Morgan Lease, EricConsidering the ubiquitous nature of networked computers, the traditional role of libraries is not as critical as it used to be. In other words, the time-honored library activities of collection, organization, preservation, and dissemination of books & journals is quickly being supplanted by the ever-present Google search. Thus, the problem to solve is less about finding & getting information but rather about using & understanding the information found. We continue to drink from the proverbial firehose. This does not foretell the demise of libraries nor librarians. Instead, it represents an opportunity to provide enhanced and value-added services above and beyond our collections. These services can be articulated as action statements such as but not limited to: analyze; annotate; cite; cluster & classify; compare & contrast; confirm; count & tabulate words, phrases, and ideas; delete; discuss, evaluate; find opposite; find similar; graph & visualize; learn from; plot on a map; plot on a timeline; purchase, rate; read at a distance; read closely; read at scale; review; save; share; summarize; tag; trace idea; transform; etc. This presentation elaborates upon these ideas with an emphasis on the possibilities of natural language processing & text mining in libraries.Publikace Otevřený přístup A Machine for Automatic Subject Indexing Using ToC(2018-06-06) Pokorný, JanThe technology developed in the National Library of Technology can extract a document’s table of content (TOC), generate relevant keywords, and suggest terms for various classification schemas (UDC, DDC, LCC, Conspectus). It can fully or substantially automate the process of generating subject access, unite it across libraries, and significantly increase accuracy and relevancy compared to subject assignments by non-specialist catalogers. Such increased quality in subject access terms is often seen in the superior subject facets generated by discovery systems and library OPAC advanced search forms.Publikace Otevřený přístup Enriching Library Metadata with APIs(2018-06-06) Mak, LucasGiven the ever-dwindling resources assigned to metadata creation, individual libraries are hard-pressed to create and maintain high quality traditional metadata across-the-board, let alone to prepare and transform legacy data into linked data. Coming up with no additional support by looking inside, one should look outside for resources that can help mitigate the situation. Nowadays, libraries no longer monopolize metadata creation. More and more special domain communities have set up Wikipedia-like crowd-sourced portals to serve information needs of their members. At the same time, there are international initiatives in the library community to set up data stores for linked data sets. Can the library tap into these rich information resources, in an efficient way, to enrich library metadata in the traditional way as well as prepare the legacy data for the big migration? This presentation will discuss how Michigan State University Libraries is able to harvest selected metadata from various library and non-library community based portals through APIs (Application Programming Interface) in a batch and automated fashion to enrich existing metadata of a popular music collection and enhance them with URIs for linked data conversion down the road.Publikace Otevřený přístup ABC: Amsterdam Blended Collections: The Local Amsterdam Cultural Heritage Linked Open Data Network(2018-06-06) Koster, LukasThe presentation will discuss the organisational and technical issues of the project on two levels: 1) the central platform (blend/aggregate or de-blend/distribute) and 2) the various local situations of participating institutions, leading to different blending/de-blending approaches, focusing on the Library of the University of Amsterdam Special Collections (using Catmandu as ETL tool for MARC to RDF).Publikace Otevřený přístup Pushing SKOS(2018-06-06) Ostrowski, Felix; Pohl, AdrianThis presentation introduces the simple knowledge organization hub (skohub), a proof of concept web service that allows to do just that based on current web standards. Given a SKOS vocubulary, the service publishes it on the web, providing RDF serializations along with a human-readable HTML front end. For each topic described in the vocabulary, a Linked Data Notifications inbox is provided, making it possible to publish and receive notifications about resources related to that topic. Finally, WebSub enables subscriptions for push notifications about resources matching a topic.Publikace Otevřený přístup The datahub: de/blending museum data(2018-06-06) Vandermaesen, MatthiasThe Flemish Museums for Fine and Contemporary Art offer an overview of the art production in the Southern Netherlands and Belgium form the Middle Ages to the Twenty-First Century. The Flemish Art Collection is a non-profit organisation tasked with promoting the collection to an international and diverse audience. Delivery of knowledge and expertise curated by the museums is a big challenge. Blending cultural object records stored accross various databases and commercial registration systems is non-trivial and prevents opening up the collections across the walls of the museums. In 2015, the Flemish Art Collection started the Datahub Project. Over the past years, a modern metadata aggregation platform was built, leveraging open source technologies and open standards. This presentation will highlight the architecture of this platform, and the design process. The Datahub platform is a service oriented architecture and consists of three major components. The core is a home grown, reusable metadata aggregator called The Datahub. This web-application is build with the Symfony framework. Metadata records are ingested via a RESTful API, stored in a MongoDB database and disseminated via an OAI-PMH endpoint. User friendly discovery of metadata is covered via Project Blacklight and geared towards museal workers as well as the general public. Finally, we repurposed the Catmandu framework for flexible and extensible setup of ETL pipelines between the registration systems of the data providers, the Datahub and the discovery interface. Since we are exchanging information about cultural heritage objects, we use the LIDO XML exchange format designed and developed by ICOM. The project taught us several valuable lessons. What are the benefits of looking across the borders of your own domain? What are key success factors? How do you identify pitfalls? But it also raises a set of new questions. How do we go from here? What’s next? The tools and the codebase are freely available under a GPLv3 license and are actively documented and maintained on Github.Publikace Otevřený přístup Blending and Debledning Data in the Daily Routine of a University Library(2018-06-07) Stille, WolfgangIn libraries, there is something like a war of opinions about library software in the last couple of years: some (in particular library management) prefer the licensing of commercial software products with strict business models, others (n particular library IT) participate in community driven open source solutions. Probably, the truth lies somewhere in between, which means that standards, interfaces, and interoperability play a more and more imortant role in the business of library IT, and thus have to be open. At the same time, monolithic commercial software solutions implying vendor lock-ins emerge, promising all-in-one one-stop-shop solutions, obstructing an objective debate between library management and IT staff. The talk intends to give some experiental report on the past, tries to answer questions and reasons of the present, and gives some vision (and hopefully discussion) on the future of library IT.Publikace Otevřený přístup Making Wikidata fit as a Linking Hub for Knowledge Organization Systems(2018-06-07) Neubert, JoachimLightning Talks (June 7), video recording is available at: http://repozitar.techlib.cz/record/1274Publikace Otevřený přístup Library Carpentry: software and data skills for library professionals(2018-06-07) Dennis, TimLightning Talks (June 8), video recording is available at: http://repozitar.techlib.cz/record/1274
