Abstract = {Component directories index components by the services 
they offer thus enabling to rapidly access them. Component directories 
are also the cornerstone of dynamic component assembly evolution when 
components fail or when new functionalities have to be added to meet 
new requirements. This work targets semi-automatic evolution processes. 
It states the theoretical basis of an on-the-fly building of component 
directories using Formal Concept Analysis, based on the syntactic de- 
scription of the components' required and provided services. In these 
directories, components are more intelligibly organized and new abstract 
and highly reusable component external descriptions are suggested. But 
over all, this organization speeds up both automatic component assembly 
and automatic component substitution.
