We illustrate this architecture with the LimSee3 authoring tool and several standard publication formats: Timesheets, SMIL, and XHTML. Categories and Subject Descriptors I.7 [Document and Text Processing]: Document Preparation -Hypertext/hypermedia, Multi/mixed media, Standards General Terms Documentation, Experimentation, Standardization.
