The attributes marked with a * are confidential and should not be disclosed outside the service provider.

Service overview
Service name	Open Information Linking for Environmental science research infrastructures (OIL-E)
Service area	data
Service phase	alpha
Service description	OIL-E is a developing framework for addressing the semantic linking requirements of environmental science e-RIs. Specifically, it is intended to provide a machine-readable bridge between the ENVRI Reference Model and other concept models related to research infrastructure, architecture and scientific (meta)data.
Customer group	RI data engineers/architects
User group	Data-driven researchers
Value	OIL-E is intended to provide technical and methodological guidance for the linking of different controlled vocabularies in order to help the construction of cross-cutting services.
Tagline	Open linking between environmental science RI reference modelling and controlled vocabularies.
Features	Captures ENVRI RM as a multi-viewpoint OWL ontology for RI architecture. Permits analysis and comparison of RI characteristics as the foundation for an ENVRI Knowledge Base. Provides a linking framework for describing the different metadata schemes and technologies used by RIs as well as to identify any semantic mappings available to convert between schemes.

Cost *	The sustainability of the ENVRI RM ontology in OIL-E is partially tied to the sustainability of ENVRI RM itself. Application of OIL-E, e.g. for the ENVRI Knowledge Base, creates a community of use for ontologies. Publication of OIL-E in ontology repositories also increases exposure and provides limited curation tied to lifespan of repository.

[1] Technology Readiness Levels (TRL) are a method of estimating technology maturity of components during the acquisition process. For non-technical components, you can specify “n/a”. For technical components, you can select them based on the following definition from the EC:

• TRL 1 – basic principles observed
• TRL 2 – technology concept formulated
• TRL 3 – experimental proof of concept
• TRL 4 – technology validated in lab
• TRL 5 – technology validated in relevant environment (industrially relevant environment in the case of key enabling technologies)
• TRL 6 – technology demonstrated in relevant environment (industrially relevant environment in the case of key enabling technologies)
• TRL 7 – system prototype demonstration in operational environment
• TRL 8 – system complete and qualified
• TRL 9 – actual system proven in operational environment (competitive manufacturing in the case of key enabling technologies)
