ELFIE

A brief introduction to the Environmental Linked Feature Interoperability Experiment (ELFIE)

Visit http://www.opengeospatial.org/projects/initiatives/elfie for more info.

Significant prior work on domain feature models and O&M.

No common-shared approach to structure, encode and dereferencing documents linking features to …

• Target 1) links between features.
• Target 2) links from observations to/from features.

URI structure, HTTP dereferencing, etc. out of scope for IE, but it may pose questions related to these issues.

• River Monitoring / Flood – river features and observations.

• Irrigation – soils linked to SW/GW resources.

• Hydrologic Drought – water storage and supply/demand.

• Water Quality – water quality impacts and observations.

… driven by participants.

1. Define testing criteria – what is success?
2. Refine use cases and collect data
3. Establish draft encodings for use in IE
4. Encode documents (by hand or by program)
5. Evaluate documents according to criteria.
6. Create visual representation of documents.
7. Write up findings.

May 2017 – Kick off and Environmental Linked Data Symposium
