Standards/Technology
1. The technology is available.standard-based, open vs. commercial
2. Standards are essential for understanding & interoperability 1. Geoscience standards: Age?, Lithology?,
Stratigraphy?2. Data model < = > Conceptual Geology model3. Exchange Formats: OGC, GML, GeoSciML? 4. Online access: WMS, WFS, WCS, etc. 5. Terminology : multiple languages?
Formats, models, systems, projections, hardware, software, etc ...?

“Schematic interoperability” means:
• This approach avoids the requirement to agree upon a single interpretation and legend and will allow delivery of geological coverage for any area of the world.
• However: OneGeology will likely contain national
"boundary faults" caused by data not being harmonized.
Data in a common data format and structure without harmonizing the content and interpretation between territories.

7) What are the technical challenges?What challenges must OneGeology address ?
1. Participants with a wide range of know-how and resources.
2. Integration of maps/data with very different format, content, and structure.
3. Delivering geological information that can be understood by non-specialists from highly technical data.
4. Establishment of dependable systems that deliver OneGeology data in real time.

SummaryKey points to remember ?
The proposed OneGeology technical approach will:
• Accommodate the needs of all participants.• Deliver structurally-consistent geological data online.• NOT require scientific harmonization of geology.• Place importance on the transfer of technology.• Allow participants to provide access to their data in
whatever form they have.• Technology is available to meet OneGeology
requirements.
