Microcontent is modular content. Each item of microcontent is an unique, individually addressible chunk of content defined by metadata focused around a particular idea or small set of related ideas.
Macrocontent is any collection of organized microcontent objects that form a publication. A weblog is actually “macrocontent” — it is a published, temporally organized collection of microcontent objects that comprise its individual “postings.” A wiki could also be seen as macrocontent — it is a published, topically organized collection of microcontent objects comprising its wiki-nodes. At a certian point in the near future I think that even common Web pages will become macrocontent — that is they will be comprised of numerous microcontent objects arranged in a particular order on the page. By constructing Web pages and Web sites out of modular units of microcontent sites will become far more useable and searchable. Furthermore, each microcontent object on the page will become a node that others can subscribe to, comment on, link to, etc. Weblogs are just the first use of microcontent — I think that in fact the microcontent paradigm will become a key element of next-generation Web publishing, and even of the desktop. When content becomes granularized into modular, semantically rich components publishing systems, publications and reading/browsing tools can all benefit from improved precision, content management and interaction capabilities.Social tagging: Weblogs
Hmm, this seems strikingly similar to “Learning Objects” in the eLearning space where, despite the metadata structured/formulated/captured these microcontent elements have proved to be less than successful. In the end it turns out as the size(volume) of the content falls so does its usefulness as a stand alone entity. Thus you end up needing metadata to provide valid combinatorial sequencing, of which there is only usually one useful one(the one you started with)
