Using blocks to get more blocks: Exploring linked data through integration of queries and result sets in block programming

While many Linked Data sources are available, there is a lack of effective non-expert user interfaces to build structured queries on them. The block programming paradigm promotes a gradual and modular approach. If - in an integrated user interface - both queries and results are represented as blocks, modularity can be effectively used to support an exploratory way of designing Linked Data queries.
