GS Dev Requirements

Geometry Service Requirements

• Geometry versioning: revision history of geometry changes such as who did what to the model and for which analysis, when changes were made, by whom, etc.
• Direct association of stored geometry with external data
• Multi-user access controls that allow multiple people to work on the same models at the same time
• Programmable access-controlled interface that utilizes reuseable code for consistent end-to-end access to geometric data.
• Dynamic geometry
• Geometryarticulation and editing constraints
• Unified repository of geometry in one storage location.
• Reuse of identical geometry parts (single instancing).
• Improved/advanced collaboration.
