Information Layers Model from Karl Fast

On SIGIA, Karl Fast proposed a rough 5 layered model for information. The layers are content, metadata, semantic, representational, and interaction.

Librarians kick ass on the metadata and semantic layers. They suck on the representational and interaction layers.

>Representational Layer

And what about catalogues? metadata is not just author names etc....

Classification systems are a mixture of arabic numbers and symbols - just as Karl suggests....

>Interaction Layer
>Lastly you have an interaction layer that defines how you interact >with the representations: how you select, manipulate, rearrange, and explore the representations.

Who designs the layout of where to find things in a good library?? Unfortunately the newer libraries on the Net are not designed by Librarians.
