1. Introduction

The Open Geospatial Consortium (OGC) is releasing this Call for Participation (CFP) to solicit proposals for the OGC Testbed-18. The Testbed-18 initiative will explore six tasks, including advanced Interoperability for Building Energy; Secure, Asynchronous Catalogs, Identifiers for Reproducible Science, Moving Features and Sensor Integration, 3D+ Data Standards and Streaming, and Machine Learning Training Data.

1.1. Background

OGC testbeds are an annual research and development initiative that explores geospatial technology from various angles. They take the OGC Baseline into account, and at the same time explore selected aspects with a fresh pair of eyes. Testbeds integrate requirements and ideas from a group of sponsors, which allows leveraging symbiotic effects and makes the overall initiative more attractive to both participants and sponsoring organizations.

1.2. OGC Innovation Program Initiative

This initiative is being conducted under the OGC Innovation Program. This program provides a collaborative agile process for solving geospatial challenges. Organizations (sponsors and technology implementers) come together to solve problems, produce prototypes, develop demonstrations, provide best practices, and advance the future of standards. Since 1999 more than 110 initiatives have taken place.

1.3. Benefits of Participation

This initiative provides an outstanding opportunity to engage with the latest research on geospatial system design, concept development, and rapid prototyping. The initiative provides a business opportunity for stakeholders to mutually define, refine, and evolve service interfaces and protocols in the context of hands-on experience and feedback. The outcomes are expected to shape the future of geospatial software development and data publication. The Sponsors are supporting this vision with cost-sharing funds to partially offset the costs associated with development, engineering, and demonstration of these outcomes. This offers selected Participants a unique opportunity to recoup a portion of their initiative expenses.

2. Technical Architecture

This section provides the technical architecture and identifies all requirements and corresponding work items. It references the OGC standards baseline, i.e. the complete set of member approved Abstract Specifications, Standards including Profiles and Extensions, and Community Practices where necessary.

Please note that some documents referenced below may not have been released to the public yet. These reports require a login to the OGC portal. If you don’t have a login, please contact OGC using the Additional Message textbox in the OGC Innovation Program Contact Form.

Testbed Threads

The Testbed is organized in a number of tasks. For organizational purposes, related tasks are handled in threads. Each thread combines a number of tasks that usually share architectural or thematic aspects. Threads allow us to keep related work items closely together.
