Description 

 
  SPARCE  stands for Superimposable 
Pluggable Architecture for Contexts and Excerpts. People often impose new interpretations (both data 
and structure) onto existing information. For example,
bookmarks to web pages, tables of contents, and 
annotatins. Information exists in two layers in this
setting: a base layer, where the original information resides, and a superimposed layer, where the new
interpretations reside. A superimposed application 
allows people to refer to information items in heterogeneous information sources (at sub-document
granularity), and to create new superimposed 
information. SPARCE is a middleware architecture
and implementation that superimposed applications may reuse.
