What is/are CyberGIS Architecture(s)?
• Internet-based, collaborative knowledge and decision environment based on the value of location information
• Best implemented when including–Open Interfaces–Open Source–Open Data

CyberGIS plumbing for collaboration is in place
Geospatial interoperability solved - several times• Geospatial Web Services: WMS, WMTS, WFS, WCS including REST• Geospatial Processing: Web Processing Service• Workflow and Model interoperability
Collaboration containers exist • OWS Context• OGC GeoPackage built on SQLite
Improvements for the big part of “CyberGIS”• Big Data applications, e.g. Apache Spark, Storm; GeoTrellis• OGC Discrete Global Grid Systems

Discrete Global Grid System (DGGS) Standards Working Group (SWG)
• Develop common criteria that will define conformant DGGSs– Considering Goodchild criteria
• Develop conceptual standard to facilitate data fusion between DGGSs using OGC Standards– to make them interoperable – with
conventional and other DGGS data– to standardize operations on them
• Engage stakeholders to encourage new use cases and adoption of interoperability through DGGSs

Knowledge Objects need to be conceptually modeled and implemented
• “Decision” and “Hypothesis” as 1st class objects– UML Model of the concepts and linked data relationships– Ontology for Types of decisions and hypothesis– Encodings of conceptual models– Templates for Decisions and Hypothesis
• Recommender systems - a guess at the riddle– If I see “these conditions” then consider this “decision template”– If I am researching “these topics” then consider this “hypothesis”
