Known Issue: The metadate framework name was changed from XAP to XMP

Summary

XAP (Extensible Authoring Publishing) was an early internal code name for XMP (Extensible Metadata Platform).

Issue
Why are many namespaces, keywords, data structures, and related names in the documents and XMP toolkit code prefaced with the string "XAP" rather than "XMP"?
Solution
XAP (Extensible Authoring and Publishing) was an early internal code name for XMP (Extensible Metadata Platform) metadata. Because Acrobat 5.0 used those names, they were retained for compatibility purposes. XMP is the formal name used the framework specification.
