  8. 8. Data Model Digital Enterprise Research Institute Observation   Adoption of “relaxed” versions of the relational data mdeol www.deri.ie Challenge   Define a data model on top of RDF that works at a more abstract level than individual triples Enabling networked knowledge
  9. 9. Data Processing Operators Digital Enterprise Research Institute Observation   Supporting a subset of relational algebra www.deri.ie Challenge   Define a subset of SPARQL algebra that is sufficient to address common needs and is amenable to distributed execution Enabling networked knowledge
  10. 10. Schema Digital Enterprise Research Institute Observation   From rigid schemas to partial or no schemas www.deri.ie Challenge   Support partial and evolving schema mapping Enabling networked knowledge
  11. 11. Programming Paradigm Digital Enterprise Research Institute Observation   A shift from pure declarative languages toward hybrid ones www.deri.ie Challenge   Adopt a hybrid declarativeimperative programming paradigm for RDF processing Enabling networked knowledge
  12. 12. In-situ Data Processing Digital Enterprise Research Institute Observation   In-place processing has become an important tool for dealing with data www.deri.ie Challenge   Support in-situ RDF data processing and in-place transformation of non-RDF data Enabling networked knowledge
