Repository as a service (RaaS)

In his oft-quoted seminal paper ‘Institutional Repositories: Essential Infrastructure For Scholarship In The Digital Age’ Clifford Lynch (2003) described the Institutional Repository as “a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members.” This paper seeks instead to define the repository service at a more primitive level, without the specialism of being an ‘Institutional Repository’, and looks at how it can viewed as providing a service within appropriate boundaries, and what that could mean for the future development of repositories, our expectations of what repositories should be, and how they could fit into the set of services required to deliver an Institutional Repository service as describe by Lynch.<br/

Q: Why is a raven like a writing desk? A: They’re both objects

The famous riddle by Lewis Carroll is not really intended to have an answer, but rather to reveal the incomprehension Alice has of the world of adults. This paper is about a team of model-driven software engineers' concepts of "object" coming up against the building design sector's concept of "object", and challenging our assumptions about the clean and clever solutions that we can create with object-oriented metamodels and model transformation and code generation tools. However, the story has a happy ending in which the application of our tools in combination with pragmatic choices of representations of building designs still produces an outcome that meets our users' needs and avoids lots of bespoke programming

Integrated Skills, Integrated Data: Mapping Best Practice and Collections for Innovation and Engagement

In recent years the University of Edinburgh [UoE] has seen change, mergers, external partnerships and innovation at the heart of its growth and activity. Collections at UoE were not immune from these changes and have pioneered projects that both support and highlight unique educational cultures. Technology and the dissemination of collections has not only engendered positive relationships with academics but has created wider opportunities for the use of collections in teaching, learning and research. This momentum and an established commitment to the interoperability of data and standards presented an opportunity to look for a global solution to collections management within the converged, cross disciplinary environment. This included harnessing expertise in the University with systems development for large European projects and wider project management. This session will explore how UoE became the first European contributor to the collections management tool Archives Space. Snapshots of a converged culture and how 'archives' have benefited from this (including how 'techies' and 'archivists' worked together). An upbeat finale will look at what the team at the UoE achieved and are excited about for the future

A Microservice based Architecture for a Presence Service in the Cloud

Presence service enables sharing of, and a subscription to the end users presence (online or offline) status. Primarily used for instant messaging applications, the presence service now finds its way into innovative solutions for domains such as wireless sensor networks and Internet of Things. The growth in users of instant messaging applications is ever increasing since the advent of social media networks. Presence service needs to be highly scalable to handle growing load of the users. Moreover, the user activity is inherently dynamic in nature which requires the presence service to be highly elastic to utilise resources efficiently. Traditional presence services are built as monoliths. Monolithic architectures by design are difficult to scale, lacks elasticity and are resource inefficient. Moreover, overprovisioning of resources to handle unanticipated loads further adds to resource inefficiency. Cloud computing and microservices are emerging paradigms that can help tackling the challenges above. Cloud computing with three key facets: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) enable rapid provisioning and release of resources (e.g. storage, compute, network) on demand. Microservices is an approach of developing applications as a set of smaller, independent, and individually scalable services which communicate with each other using lightweight protocols. The on-demand nature of cloud computing provides a platform to achieve elastic scalability whereas microservices increase the scalability of the architecture. This thesis presents a microservice architecture for a presence service in the cloud. The architecture is based on a state of the art business model. The proposed architecture has three main components: A stateless front-end, a repository and a cache. The front end is built as a set of microservices exposed as SaaS. The front end, to remain technology agnostic, communicates with the repository using the Representational State Transfer (REST) interface. The cache provides fast data access to the front end. The front end microservices use message queues to communicate with each other. Besides, to check the feasibility of the architecture, a proof of concept prototype is implemented for a Session Initiation Protocol for Instant Messaging and Presence (SIMPLE) based presence service. Performance measurements have been made for the proposed and traditional architectures. Also, a comparative analysis of the results is done. The analysis of the results shows that the proposed architecture provides the desired scalability and elasticity to the presence service. Moreover, the proposed architecture provides lower response time and higher throughput in comparison to the traditional architecture

European Language Grid

This open access book provides an in-depth description of the EU project European Language Grid (ELG). Its motivation lies in the fact that Europe is a multilingual society with 24 official European Union Member State languages and dozens of additional languages including regional and minority languages. The only meaningful way to enable multilingualism and to benefit from this rich linguistic heritage is through Language Technologies (LT) including Natural Language Processing (NLP), Natural Language Understanding (NLU), Speech Technologies and language-centric Artificial Intelligence (AI) applications. The European Language Grid provides a single umbrella platform for the European LT community, including research and industry, effectively functioning as a virtual home, marketplace, showroom, and deployment centre for all services, tools, resources, products and organisations active in the field. Today the ELG cloud platform already offers access to more than 13,000 language processing tools and language resources. It enables all stakeholders to deposit, upload and deploy their technologies and datasets. The platform also supports the long-term objective of establishing digital language equality in Europe by 2030 – to create a situation in which all European languages enjoy equal technological support. This is the very first book dedicated to Language Technology and NLP platforms. Cloud technology has only recently matured enough to make the development of a platform like ELG feasible on a larger scale. The book comprehensively describes the results of the ELG project. Following an introduction, the content is divided into four main parts: (I) ELG Cloud Platform; (II) ELG Inventory of Technologies and Resources; (III) ELG Community and Initiative; and (IV) ELG Open Calls and Pilot Projects
