- 3.1 Dynamic Metadata Source

Overview

Identified by type="Dynamic", this MetadataProvider loads metadata on-demand from an HTTP server. The precise URL accessed is derived from the entityID of the peer and may be literal (i.e., that entityID) or more commonly constructed based on a simple substitution or transform involving the entityID. It is optimized to be reliable and efficient by caching in-memory and on-disk and by preventing unnecessary re-processing via HTTP caching support.

Reference

The type="Dynamic" attribute must be present.
