The DLI Service: an open one-for-all data-literature interlinking service
Introduction and vision
The serviceThe DLI Service populates and provides access to a graph of “authoritative” dataset-literature links collected and aggregated from a variety of major data centers, publishers, and research organizations. It is intended to offer facilities for the following classes of actors
- End-users: searching and browsing the graph of links via the portal
- Third-party service developers: accessing publications and datasets in the graph via programmatic APIs
- Content providers: willing to feed high-quality authoritative links between publications and datasets or between datasets to the service (complete list of content providers).
Based on feedback from content providers and consumers, The DLI Service will refine its underlying interlinking data model and exchange format to make it a universal, cross-platform, cross-discipline solution for collecting and sharing dataset-literature links, balancing between the information that can be shared across content providers and the information needed by its consumers.
In the forthcoming months further work will be carried out towards the delivery of a production service that is fully reliable in terms of QoS and quality of content. The following actions will be undertaken:
- Definition of a content acquisition policy: minimal quality requirements to be respected by content providers in order for their publications, datasets and relative relationships to be aggregated by the system;
- Definition of SLAs for content providers: make sure content providers are aware and agree on how their content (metadata) will be made openly accessible via the service;
- Technical enhancements: data harmonization (e.g. cross-PID deduplication), data programmatic access (e.g. high-throughput resolver), data scalability (e.g. moving away from open source databases).
- Deployment as an OpenAIRE infrastructure operational service: deploying the service on the OpenAIRE hardware infrastructure.
