The key innovation of the product is flexibility of publishing versus other systems. Libero fully supports continuous publication in a way that puts the publisher in control. The publisher decides when they publish, how the conversion of articles to web pages works, which post publication activities are required, as well as having extensible workflow and customisable reporting at their fingertips. Flexible versioning is also a key differentiator from other similar systems with the ability to update article content over time, even after the Version of Record is published. When this occurs the system manages access to all previous iterations for users. This flexibility and control is not available in other publishing systems in the market.
The service has been designed specifically for Open Access publishing which results in a much better product than other licensed content systems that have been subsequently adapted for OA which leads to a convoluted design and a range of usability and technical issues as a result. Due to ease of use and low running costs Libero Publishing Cloud will make Open Access publishing more feasible for a wider range of journals and in so doing help increase the proliferation of Open Access publishing.
The modular architecture used to compose the Libero open source platform helps facilitate the creation of a highly configurable and robust hosting infrastructure that can meet the scalability and resilience needs of very small to very large publishers. Different elements of the platform are naturally separated from each other; large ingest and publication runs, for example, don’t have any impact on the content delivery from the journal website. Similarly spikes in concurrent user activity has no impact on the content processing components.
The service is delivered using Amazon AWS hosting platform and benefits from the many advantages this service provides. Some of these include load balancers to manage traffic between multiple servers, the ability to plug in content delivery networks (CDN) services to deliver images and data to your end users with high transfer speeds and low latency.
eLife together with Digirati and other publishers are working to develop a community to enhance and prioritise a development roadmap for the Libero open source platform. Until recently, all improvements to the platform were made by eLife and Digirati to improve their own offerings while enabling more reuse in the community. We now want to engage the community to ensure that the platform evolves in a way that will benefit as many publishers as possible.
Currently the platform processes XML content using the JATS format and following the JATS4R guidelines. Image interoperability standards have been included taking advantage of the IIIF Image API 2.0 to deliver figures and images within scholarly content. User interface design focussed on accessibility and performance employing a progressive enhancement approach to ensure inclusion for readers.
Our services benefit from AWS cloud security, which was designed to meet the requirements of the most security-sensitive organisations. In addition to this, we make use of its services, such as identity access management (IAM), to restrict access to only what's necessary to our applications and to developers. An API Gateway is used to isolate and control access to the platform’s APIs. The applications that exist within the solution also rely on user authentication with further enhancements and auditing features being added.
