  • CliqueSquare: massively parallel RDF data management

    -

    CliqueSquare is a system for storing and querying large RDF graphs relying on Hadoop’s distributed file system (HDFS) and Hadoop’s MapReduce open-source implementation. It provides a novel partitioning and storage scheme that permits 1-level joins to be evaluated locally using efficient map-only joins. In addition, CliqueSquare is equipped with a unique optimization algorithm based on graphs and cliques capable of generating highly parallelizable flat query plans relying on n-ary equality joins.

  • StarLion

    -

    StarLion is a visualiation tool (java application) for RDFS/XML files. It can load ontologies expressed in .rdf/.rdfs files or stored at the FORTH-ICS Semantic Web Knowledge Middleware (http://athena.ics.forth.gr:9090/SWKM/) and present them as graphs to the end user.

  • XR: an XML-RDF Hybrid Model for Annotated Documents

    -

    The XR management platform thus provides the capabilities to create and handle interconnected XML and RDF content. It is based on the XR data model and provides querying capabilities to end user through its query language XRQ.
