Benchmarking RDF Metadata Representations: Reification, Singleton Property and RDF*
International Computer Science Conference, 2021RDF reification is a data modelling solution for writing RDF statements about RDF statements. A set of approaches exist in the literature to express statement-level metadata, or “reified” statements, in RDF.

and how? How are the properties we use to define our individuals related to other sets of individuals and, indeed, to one another? RDFS provides a way for an information modeler to express the answers to these sorts of questions as they pertain to ...

The index organizations for RDF and RDF schema
2006 8th International Conference Advanced Communication Technology, 2006In semantic Web, metadata and ontology for representing semantics and conceptual relationships of information resources are essential factors. RDF and RDF schema are the W3C standard models for describing metadata and ontology. Therefore, storing and querying RDF and RDF schema is one of major tasks in applications on the semantic Web.

RDF Data Storage and Query Processing Schemes
ACM Computing Surveys, 2018The Resource Description Framework (RDF) represents a main ingredient and data representation format for Linked Data and the Semantic Web. It supports a generic graph-based data model and data representation format for describing things, including their ...

Compression of RDF dictionaries
Proceedings of the 27th Annual ACM Symposium on Applied Computing, 2012The use of dictionaries is a common practice among those applications performing on huge RDF datasets. It allows long terms occurring in the RDF triples to be replaced by short IDs which reference them. This decision greatly compacts the dataset and thus mitigates its scalability issues. However, the dictionary size is not negligible and the techniques

The World Wide Web Consortium's RDF standard primarily consists of (subject, property, object) triples that specify the value that a given subject has for a given property. However, it is frequently the case that even for a fixed subject and property, the value varies with time.

This paper studies the compressibility of RDF data sets. We show that big RDF data sets are highly compressible due to the structure of RDF graphs (power law), organization of URIs and RDF syntax verbosity. We present basic approaches to compress RDF data and test them with three well-known, real-world RDF data sets.
