The most important part of any Corda® image is the data it represents. While Corda Builder™ lets you manually specify data for each object in a Corda image, one of Corda Server's most useful features is its ability to import live, dynamic data into Corda images.
Use Corda images as templates (Image Template files) to represent live data. When you request an image from Corda Server™, it replaces the sample data in the Image Template file with live data. Corda Server can automatically rescale, resize, and reposition objects in an Image Template file if the live data set is significantly different from the sample data in the Image Template file. For more information, see Dynamically Resizing the Image Template File in the Corda Builder User Guide.
When preparing to use dynamic data sources with Corda Server, consider the following:
A common error when loading dynamic data is neglecting to configure Corda Server security settings so that it can load data from the specified location. To load data from a location other than the local <document_root>, configure path.xml to include this location. A Corda Server administrator can do this. For more information, see Setting Path Permissions in the Corda 7 Install and Administration manual.
You cannot load data from a URL accessed through a proxy server.
Make sure that the data is organized in a way that is consumable by the graph type or map that displays it. For more information, see Data Organization in the Corda 7 Graph Guide.
Corda Server can load data from the following sources:
