Sampo-UI

Sampo-UI is a framework for developing user interfaces for semantic portals. The underlying ideas of the framework are based on the "Sampo" model that contains a sustainable business model for publishing and sharing Linked Data based on a shared ontology infrastructure, the idea of providing the end-user with multiple application perspectives to the Linked Data, and a two-step usage cycle based on faceted search combined with ready-to-use data-analytic tooling. The framework draws from longstanding research of the Semantic Computing Research Group since 2002 on developing semantic portals, which has resulted in publishing a series of "Sampo" portals, mostly related to the Cultural Heritage domain, that have had millions of end-users on the Web. The Sampo-UI framework makes it possible to create highly customizable and responsive user interfaces that satisfy the requirements for such portals using current state-of-the-art JavaScript libraries and data from SPARQL endpoints, while saving substantial coding effort. Sampo-UI is published on GitHub under the open MIT License and has been utilized in several internal and external projects.

For more information about the "Sampo" model and how Sampo-UI has been applied in semantic portals see the Sampo portals homepage.

More information is also available on the publications below as well as on the GitHub repository.

Software

Sampo-UI is available on GitHub: https://github.com/SemanticComputing/sampo-ui.

Demo Portal

An example portal built with the latest version of Sampo-UI is published at sampo-ui.demo.seco.cs.aalto.fi. It combines sample perspectives and templates from existing portals, and can be used for testing and as a "starting base" for developing new user interfaces.
