Environmental Information Data Centre: enabling the discovery of CEH-held data
John WatkinsDeputy Director EIDC
CEH & NERC in a UK Government setting
CEH monitoring and data collection
• As diverse as our science
• Micro- to macro-scale
• Many sources:• Monitoring campaigns• 180+ field sites• State-of-the-art facilities• Regulator networks• Volunteers• Model outputs
• Long-term and unique

“.....the datahave been allocated a digital object identifier (http://dx.doi.org/10.5285/1a91c7d1-ec44-4858-9af2-98d80f169bbd).”
Harmonising data definitions
CEH Analytical Services Thesaurus (CAST)
No specified vocabulary!
Making definitions open access
CEH Analytical Services Thesaurus (CAST)• Created to Simple Knowledge Organization System (SKOS) W3C standard• Designed to describe whole process• Top concepts:
• determinands• machine descriptions• measurement units• methods• filtration• preservation
Importing definitions through Web links
Importing information through Web links
Resource oriented discovery
CEH Analytical Services Thesaurus (CAST)• SKOS allows links to externally hosted vocabularies e.g. ChEBI
• adds further value to datasets tagged using CAST, as they can be integrated with datasets tagged using concepts from linked vocabularies

Enabling complex environmental queries
Web as a research data resource
Issues & challenges
• Researchers can ask complex questions across diverse data sources using LOD
• How to incentivise data providers to document & tag data => buy-in (e.g. DOIs)!
• Tools to automate the process, tagging at source/time of creation (e.g. LIMS)
• Automating the creation of semantic information for legacy data using diverse information sources (e.g. text mining of past reports and science papers)
