P UBLISHING AND R ETRIEVING
State of the Art
Large & active SW community in science, government, & industry
Many open source and commercial tools and infrastructures
Existing ontologies and huge amounts of interlinked data
Integration of semantics into scientific workflows
SPARQL querying and faceted browsing
Frontiers
Further lower the initial hurdle to publish individual datasets
Modular ontologies that go beyond mere surface semantics
Ontologies for scientific workflows and e-Science
Linked Data query federation and semantic search
Data Provenance (Ontology)
Roadmaps
Stronger reasoning support during publishing and retrieval of data
Data Fridge to slow down the semantic aging of (meta)data
Change in social/scientific culture towards open data and models

I NTERACTING AND A CCESSING
State of the Art
Semantic technologies & ontologies reduce implementation and
maintenance costs
Simple interplay between Spatial Data Infrastructures and the
Semantic Web
Open Ontology Repositories
Access external datasets via own preferred user interface
Highly modular and distributed, no SPOF
Frontiers
Integration of Linked Data into environment such as R and GIS
Interactive and online workbenches for querying and linking data
Linked Data compression
Roadmaps
Linked Data and semantic technologies as seamless and
transparent cyberinfrastructure
Exploratory search, information seeking, and navigation

R EUSING AND I NTEGRATING
State of the Art
Simple semantic alignment and translation
Semantic linking frameworks
Satisfiability checking and related reasoning service
Frontiers
Data-Model Intercomparison
Semantic technologies support for integrity constraint checking
Complex semantic alignment and translation
Data-driven, collaborative, interdisciplinary ontology engineering
Approaches towards better support of vagueness and uncertainty
Roadmaps
