Developing an App with Xpress Insight

Covered Topics

• How Xpress Insight Interacts with a Mosel Model
  Xpress Insight executes Mosel models by using the XPRD library to send the model to an xprmsrv instance using the distributed Mosel mechanism.
• Xpress Insight Model Requirements
  Mosel model developers must implement several features in a model to use it in Xpress Insight.
• Supported Mosel Features, Types and Data Sources
  In general, so long as the requirements listed previously are met by a model, Xpress Insight places no restrictions on the programmatic execution of a model.
• The Xpress Insight Repository
  An app is the top-level node in the repository.
• The App
  Apps can be added to the system by uploading ZIP archives containing all required files.
• Custom Execution Modes
  Execution modes allow for two forms of control in your app.
• Data Management and Scalability
  When the first scenario of an app is loaded, the schema of the model is captured.
• Basic Presentation Customizations
  Earlier, amodel was loaded into the Xpress Insight application with the minimal required changes. Once deployed, the named entities in the model are presented to the user unchanged, and anonymous entities in the model are not visible.
• Debugging Aids
  Xpress Insight provides a fully-featured debugger which is seamlessly accessed from Xpress Workbench.
• Using Attachments
  The web client provides a way to attach files to an app and individual scenarios. These attachments can be accessed from Mosel, providing another way to interact with the model.
