“…The LDW allows completely open applications which access data sources on the fly, discovering new ones at runtime, rather than relying, as in the Web 2.0 mashup world, on data sources fixed in advance [51]. The use of the RDF data model simplifies data access in comparison to Web APIs, which use heterogeneous data models and thereby restrict access [46].…”

“…WebBox extends the role of the Web server from a document publishing platform to one that fundamentally supports distributed collaboration on data artefacts, specifically RDF resources -and shows that this can be achieved without the need for major reinvention. This is an implementation of Socially-Aware Cloud Storage [43,46] in which social-sharing Web applications access a usercontrolled data space for private storage and shared resources, entirely under the user's control. Thus, unlike existing centralised sharing platforms where data and applications are inextricably tied, data can be used by multiple applications and services, and shared directly between peers.…”

“…A fine grained update language is important for enabling a Read-Write Web of Data [3], where contributing content is as important as consuming content. SPARQL Update is currently being developed by the W3C as a standardised fine grained update language for RDF, for which an operational semantics is beneficial [9].…”

Operational Semantics for SPARQL Update

Abstract. Concurrent fine grained updates are essential for using RDF stores in dynamic modern Web applications, where users increasingly contribute content as often as they read content. SPARQL Update is a language proposed by the W3C for fine grained updates for RDF stores. In this work we propose an operational semantics for an update language for RDF, which models core features of SPARQL Update. Firstly, an abstract syntax for RDF and updates is presented. Secondly, the operational semantics is defined using relations over the abstract syntax. The operational semantics specifies all possible operational behaviours of updates in the presence of an RDF store. The specification is useful as a common reference for compiler engineers and as a foundation for the static analysis of updates.

Abstract. Linked Open Data faces severe issues of scalability, availability and data quality. These issues are observed by data consumers performing federated queries; SPARQL endpoints do not respond and results can be wrong or out-of-date. If a data consumer finds an error, how can she fix it? This raises the issue of the writability of Linked Data. In this paper, we devise an extension of the federation of Linked Data to data consumers. A data consumer can make partial copies of different datasets and make them available through a SPARQL endpoint. A data consumer can update her local copy and share updates with data providers and consumers. Update sharing improves general data quality, and replicated data creates opportunities for federated query engines to improve availability. However, when updates occur in an uncontrolled way, consistency issues arise. In this paper, we define fragments as SPARQL CONSTRUCT federated queries and propose a correction criterion to maintain these fragments incrementally without reevaluating the query. We define a coordination free protocol based on the counting of triples derivations and provenance. We analyze the theoretical complexity of the protocol in time, space and traffic. Experimental results suggest the scalability of our approach to Linked Data.
