A quick question:

"The novel /The Heart of Midlothian/ by Sir Walter Scott will always be 
titled "The Heart of Midlothian" and be by Sir Walter Scott."

Does that mean that if a spelling mistake occurs in the RDF for the 
title of this novel, that it's incorrect in perpetuity? Or that it has 
to be corrected by hand in every library?

That seems unfortunate.

Naturally, if this spawns additional questions, please ask.

> A BIBFRAME Annotation is a resource that enhances our knowledge about the resource it annotates (the target resource).  A BIBFRAME Annotation manages this in one of two ways.  One way is for the BIBFRAME Annotation to facilitate an association between two resources by means of relationships.  The resource being annotated is the target of the annotation while the resource that otherwise enhances our knowledge of the target resource is the body, or payload, of the annotation.  The BIBFRAME Annotation, in this case, serves to say, "Resource A annotates Resource B, the target resource."  The other way is for the BIBFRAME Annotation to be itself the carrier of additional information about the target resource.  In this alternative, the BIBFRAME Annotation does not function as a lightweight abstraction layer bridging two resources, but an end resource that further enhances our knowledge about the target resource.  As a matter of focus, a BIBFRAME Annotation generally refines our understand
ing of the target resource as a whole versus any one particular aspect or segment of the target resource.

> Another distinguishing characteristic about a BIBFRAME Annotation, as distinct from a BIBFRAME Work or BIBFRAME Instance, is that *who* asserted the Annotation is of paramount importance.  The *who* being the agent stating, "This annotates that."  The importance may range from simply wanting to know, for the sake of completeness, the source of the added information to needing to make a value judgment predicated on the identity of that source.  The latter is particularly meaningful when the additional information may be subjective in nature.  Reviews and ratings fall squarely into the realm of subjectivity, where knowing *who* is asserting the value of the review (not to mention the identity of the reviewer) may directly inform how the Annotation is treated.

> Another way to define a BIBFRAME Annotation in this regard is by contrast to other BIBFRAME resources.  In the BIBFRAME universe, most of the "facts" about BIBFRAME Works, Instances, and Authorities are immutable, and they will likely be of interest to most users.  Creators, producers, authors, editors, places of publication, publication dates, publishers, manufacturers, titles, and much more, do not change per individual resource.  The novel /The Heart of Midlothian/ by Sir Walter Scott will always be titled "The Heart of Midlothian" and be by Sir Walter Scott.  Likewise, the instance published in 1878 in New York by G. Munro cannot shake those facts in just the same way the instance published in 1885 by J.W. Lovell and company (also in New York) cannot escape from those facts.  These are unquestionably objective "facts" about those resources.  However, reviews of the Work will be subjective and come from a myriad of sources, some of which may be more trusted than others or may be 
more suitable to some audiences than others.

> Using the BIBFRAME Annotation model for game ratings provides another example.  The Entertainment Software Rating Board (ESRB) assigns ratings to games based on content and age.  Australian Classification Board does this for the Australian market.  The Computer Entertainment Rating Organization (CERO) is the Japanese equivalent of ESRB.  The South Koreans, Germans, Europeans, and many more groups have their own rating systems.  In the United States, Common Sense Media is an alternative rating system that places special emphasis on age appropriateness.  Rating systems abound and, despite similarities, each will be distinctive to their markets and audiences.  Not only do the systems, by their nature, proffer subjective evaluations of media content, their value is only fully realized when we know *who* has assigned a particular game rating.  The BIBFRAME Annotation model provides a flexible way to enhance the description of Works and Instances while enabling a scenario that maintains a
 certain separation between objective "facts" and subjective ones.

> The valuable information added by the BIBFRAME Annotation is, objectively, no less (or more) important than the information associated directly with a BIBFRAME Work, Instance, or Authority.  It is just that the information conveyed by means of a BIBFRAME Annotation is in enriched by knowing *who* asserted the BIBFRAME Annotation.  As a practical matter, the *who* in this model can become a filter, allowing consumers (libraries certainly, but potentially also patrons) to select annotations based on who asserted the annotation.
