Buzzwords. Glorious buzzwords. Has anybody here looked at this ?
1. The Exchange Model
The Blocks exchange model supports two classes of applications:
mixers, which skulk information resources, transform the underlying data,
and then store the resulting metadata; and, builders, which retrieve
information about resources, evaluate those resources according to one or
more domain-specific criteria, and then publish dynamic, sharable
These applications organize information into navigation spaces using a
three step process:
1.A program "mixes" information by examining information about resources,
applying one or more transformations on the underlying data, and then
storing the resulting metadata as structured objects, termed "blocks". This
technique is termed the "skulk, transform, and store" paradigm.
2.Algorithms for evaluating and publishing sets of objects are written in
scripting languages and their metadata are stored as blocks. Evaluation
algorithms are given a collection of objects and derive relationships
between them. In contrast, publication algorithms are given a collection of
objects and relationships and determine the layout of those objects for a
3.A program "builds" navigation spaces by querying the datastore for
"interesting" objects, applying one or more evaluation scripts to those
objects, and then applying a publication script to the related objects.
This technique is termed the "retrieve, evaluate, and publish" paradigm.
