iStandUK has created a prototype service at http://www.openpublicdata.com to illustrate how Linked Data, published from many sources, can be listed, queried and presented, in real-time. You can find instructions on how to try the service at https://docs.google.com/document/d/1xKlW6cB4GuCpYSbGveoW6Zg77KXH1hQDgiDJlAp5qMM/edit?usp=sharing
… where we would also value your feedback so do add comments to the document.
The service uses the Shapes Constraint Language (SHACL), which is a W3C Working Draft, to describe the classes and properties which are present in a linked data dataset, and then associates them with ‘endpoints’ where those ‘shapes’ can be found.
You can create an account, and define your own shapes and datasets, and create widgets so that the data can be listed, queried and presented elsewhere.
