Information about the planning underway for the MARC replacement can be found in Sally McCallum’s slides from a talk given at IGeLU: http://igelu.org/wp-content/uploads/2012/09/IGeLU-sally-McCallum.pptx. These includes interesting glimpses into the future. A timeline information on slide 29 predicts Phase 1.5, early experimentation with a very small group, should take place October-November.
I recently published an article in the Journal of Library Metadata comparing MARC’s death with Language death http://www.tandfonline.com/doi/abs/10.1080/19386389.2012.700604 and discussed what language planning and death could teach us about MARC’s replacement. The most recent slideshow illustrates how essential it is to develop a common understanding of words. When you use pre-existing words to convey specific concepts with a non-typical meaning, people are not going to realize that they don’t understand each other.
Annotation is usually defined as a critical or explanatory note or body of notes added to a text. Slide 24 uses the term Annotation as “a resource that decorates other MARCR resources like holdings, cover images and reviews”, thus changing the definition from explanation to decoration.
Slide 23 delineates four core classes. The Work class reflects the conceptual essence of the item “roughly equivalent to a FRBR work or expression”. Instance, a word usually defined as a case or occurrence, now as a core class means “a resource reflecting an individual, material embodiment of the Work” , a good definition, but also different.
Interesting wording on Slide 18 as both FRBR and RDA are called “previous efforts” implying they are in the past, when RDA is yet to be completely implemented.
Language also grows through the creation of totally new words. In such cases definitions are created through context. Eric Miller (Zepheira) tweeted “these slides are high level MARCitecture in nature, details soon” See: https://twitter.com/erimille/status/250343696510353408. At least it is easily discernible what that word means.
