When a system compiles mathematical material from multiple sources, a management effort to maintain uniform and appropriate notations becomes necessary. Additionally, the need arises to facilitate the notations editing of the mathematical objects with authoring tools. In this paper, we present our work towards those needs. We have designed a framework that defines an authoring cycle supported by series of tools, which eases the creation of notations for the symbols in the process of publishing mathematics for the web.}, doi = {10.1007/11618027}, projects = {LeActiveMath}, rights = {public}, isbn = {3-540-31430-X}, selected = {true}, keywords = {authoring, content, contexts mathematical notations, presentation, rendering, } } @inproceedings{Ullrichetal-Presentation-ICALT04, title = {A Flexible and Efficient Presentation-Architecture for Adaptive Hypermedia: Description and Technical Evaluation}, author = {C.
