The AWS Panorama application manifest
When you deploy an application, you provide a configuration file called an application manifest. This file
defines the application as a graph with nodes and edges. The application manifest is part of the application's
source code and is stored in the graphs directory.
Example graphs/aws-panorama-sample/graph.json

],
"edges": [
{
"producer": "camera_node.video_out",
"consumer": "code_node.video_in"
},
{
"producer": "code_node.video_out",
"consumer": "output_node.video_in"
},
{
"producer": "log_level",
"consumer": "code_node.log_level"
}
]
}
}Nodes are connected by edges, which specify mappings between nodes' inputs and outputs. The output of one node connects to the input of another, forming a graph.
JSON schema
The format of application manifest and override documents is defined in a JSON schema. You can use the JSON schema to validate your configuration documents before deploying. The JSON schema is available in this guide's GitHub repository.
