1st year reviewLuxembourg, December 2011

The idea

PlanetData‘s aim and objectives

• Aim: establish an interdisciplinary, sustainable European community on large-scale data management• Purposeful data exposure• Novel and improved applications

• Objectives• Addressing challenges through integrated research• Data and technology provisioning through PlanetData Lab• Impact through training, dissemination, standardization

and networking• Openness and flexibility through PlanetData Programs

WP 8 Project Management

Expected outcomes (i)

• Research on publishing and managing new species of interlinked data sets• Methods and techniques to publish, access and

manage stream data

• Research on improving the usefulness of existing linked data sources• Quality assessment for interlinked data sets (for

LOD and stream data), including best practices for the representation and usage of contextual information

• Provenance, trust, access control (for LOD and stream data)

Expected outcomes (ii)

• Catalogues of data sets and vocabularies, including best practices for publishing and managing self-descriptive data

• Catalogues of data provisioning and management tools, including best practices on how to exploit clouds and clusters for distributed and large-scale data management

• Linked services and processes as an instrument to develop applications

Expected results (iii)

• Yearly summer school co-located with the ESWC

• Open training infrastructure

• Semantic Web video journal

• PlanetData Programs

Highlights of the first year

Publishing and managing new species of interlinked data sets

• W3C SSN ontology documenting RDF data streams

• URI definition • Supporting technology

• Extensions to SPARQL (SPARQL-STR)• Data stream management systems (e.g.,

MonetDB)• Transformation/characterisation tools (e.g.,

Pachube2RDF)

Improving the usefulness of linked data sourcesQuality assessment combining database techniques

with requirements from the Web of Data (LOD), and model-based techniques to clean sensor data

GeoVocab to represent geospatial informationGADM and NUTS region data and services published

with mapping to relevant data sets in the LODC

• Provenance of SPARQL queries based on relational models

• Annotation model for access control access control mechanism taking into account RDFS entailnment
