The kinds of the drawings' commands
The version of animate-data-converter that extracted the definition. What reads a definition tells by it whether it can (a version it does not read, or one newer than it knows of, which may hold what it leaves out)
Which form the definition is in
Every drawing of the content, identical ones merged (shared by every symbol that shows them)
Features found in the content that this version cannot represent
lib.properties.manifest: the images and sounds the content loads
Primitive entries of the published lib.properties (width, height, fps, ...)
The slots of every symbol without their initial values, identical ones merged
lib.ssMetadata
Every symbol, by its id
The definition as extracted: the expanded definition with nothing left out but each value written once (
expandgives the expanded form back exactly). Published content has no root of its own: the HTML template merely instantiates one of the symbols. Every symbol inlibis extracted on an equal footing; which one to use as a root is up to the consumer.
