Pushing SKOS
Ostrowski, Felix; Pohl, Adrian
2018 - English
This 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.

A Machine for Automatic Subject Indexing Using ToC
Pokorný, Jan
2018 - English
The 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.

Fundamentals

Let’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.

The Delicate Dance of Decentralization and Aggregation: keynote speech
Verborgh, Ruben
2018 - English
Ruben 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.

Moving from Find & Get and Towards Use & Understanding
Morgan Lease, Eric
2018 - English
Considering 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.

The ARCLib Project
Růžička, Michal
2018 - English
The 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.

Rethinking the IT system architecture
Berthold, Henrike
2018 - English
The 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.

In Out, In Out, And Shake It All About
Stevenson, Jane
2018 - English
The 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.

From Hydras to TACOs
Harlow, Christina; Fahy, Erin
2018 - English
Stanford 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.
