Dynamic Linked Data via Linked Open Services

The establishment of Linked Data principles has ushered in a remarkable new era of widespread semantics-based interoperation. In particular, the use of RDF, SPARQL and HTTP allows for a high degree of generic tool support and lightweight composition of data sources. This rosy picture, however, mainly applies to static data. When it comes to dynamics both on-the-fly computation and the causation of side effects the current norm is to drop the use of RDF in favour of JSON and XML. By introducing updates, the core SPARQL standard starts to address dynamics, but only in a very limited manner. Similarly, while the use of HTTP is preserved, REST principles are also often abandoned. Linked Open Services establish principles for semantics-based interoperation and interlinkage in a dynamic environment, building on both Linked Data and REST principles and the use of HTTP, RDF and SPARQL.
