This is a demo example of using the SeCo SPARQL Widget for simple application development. The demo reuses the data underlying the classic MuseumFinland portal from 2004, published as a Linked Data Finland SPARQL service. Here three facets are constructed dynamically by showing always only feasible selection options to the user, and autocompletion, not available in the original application, is supported. Ontological reasoning based on the subClassOf and partOf hierarchies is dynamic using SPARQL path expressions. For example, by selecting "Helsinki" as the place of manufacturing also artifacts manufactured in the suburbs of Helsinki, such as "Pasila", are found. Notice how little HTML code needed for the functionalities.
