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. 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. 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. 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. 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
