Although Big RDF management is an emerging topic in the so-called Web of Data, existing techniques disregard the dynamic nature of RDF data. These RDF archives evolve over time and need to be preserved and queried across it. This paper presents v-RDFCSA, an RDF archiving solution that extends RDFCSA (an RDF self-index) to provide versionbased queries on top of compressed RDF archives. Our experiments show that v-RDFCSA reduces space requirements up to 35 − 60 times over a state-of-the-art baseline, and gets more than one order of magnitude ahead over it for query resolution.
