The Open Geospatial Consortium (OGC®) IndoorGML Standards Working Group seeks public comments on the candidate OGC IndoorGML Encoding Standard.
The candidate OGC IndoorGML Encoding Standard has been developed to provide a common schema framework for interoperability between indoor spatial applications. These cover a wide spectrum of application areas such as indoor location services, indoor web map services, indoor emergency control, guiding services for visually handicapped persons in 
indoor space, and indoor robotics. Cross-platform, vendor-neutral communication of indoor spatial information is essential to meet the market demands of these applications. The international participants in the IndoorGML Standards Working Group worked in collaboration with indoor navigation information standards groups in other standardization organizations including ISO/TC204 and IEEE Robotics & Automation Society (RAS).
IndoorGML is currently implemented as an application schema of the OGC Geography Markup Language Encoding Standard version 3.2.1. IndoorGML’s minimal set of geometric and semantic data elements related to construction components is consistent with other standards such as the OGC’s CityGML standard and buildingSMART’s Industry Foundation Classes (IFCs).
IndoorGML specifies conceptual models and XML schema based on cellular space representation for the following information about indoor space:
• Geometric and semantic properties of spaces and connectivity
• Navigation context and constraints
• Space subdivisions and types of connectivity between spaces
• Navigation networks (logical and metric) and their relationships
The IndoorGML Standards Working Group (SWG) will consider all submitted comments for changes to the final draft of the IndoorGML Standard. The 30-day comment period ends March 21, 2014.
All OGC standards are free and publicly available at http://www.opengeospatial.org/standards. The candidate OGC IndoorGML Encoding Standard is available at http://www.opengeospatial.org/standards/requests/117.
