Question

Write the properties of resources

Answer 1

• Session properties allow your plug-ins to easily cache information about a resource in key-value pairs. The values are arbitrary objects. These properties are maintained in memory and lost when a resource is deleted from the workspace, or when the project or workspace is closed.
• Persistent properties are used to store resource-specific information on disk. The value of a persistent property is an arbitrary string. Your plug-in decides how to interpret the string. The strings are intended to be short (under 2KB). Persistent properties are stored on disk with the platform metadata and maintained across platform shutdown and restart.
