The continuous growth of the Linked Data Web brings us closer to the original vision of the Web as an interconnected network of machine-readable resources. There is, however, an essential aspect in principle still missing from this vision, i.e., the ability for the Web user to interact directly with the Linked Data in a read/write manner. In this presentation we introduce a lifecycle and associated mechanism to enable a domain-agnostic read/write interaction with Linked Data in the context of a single data provider. Our solution uses an ontology to build a binding front-end for a given RDF model, in addition to RDFa to maintain the semantics of the resulting form/widget components. On the processing side, a RESTful Web service is provided to seamlessly manage semantic widgets and their associated data, and hence enable the read/write data interaction mechanism. The evaluation shows that the generation process presents no performance issues, while the content overhead required for the actual form-data binding is kept to a minimum.
