Abstract. Complex workflows require intelligent interactions. In this paper we attack the problem of combining user interfaces of specialized applications that support different aspects of objects in scientific/technical workflows with semantic technologies. We analyze the problem in terms of the (new) notion of full semantic transparency, i.e., the property of user interfaces to give full access to an underlying semantic object even beyond application lines. In a multi-application case full semantic transparency is difficult, but can be achieved by representing the semantic objects in a structured ontology and actively supporting the application-specific framings of an object in a semantic interface manager. We evaluate the proposed framework in a situation where aspects of technical constructions are distributed across a CAD system, a spreadsheet application, and a knowledge base.

1 Authoring documents in MKM formats like OMDoc is a very tedious task. After years of working on a semantically annotated corpus of S T E X documents (GenCS), we identified a set of common, timeconsuming subtasks, which can be supported in an integrated authoring environment. We have adapted the modular Eclipse IDE into S T E XID E, an authoring solution for enhancing productivity in contributing to S T E X based corpora. S T E XID E supports context-aware command completion, module management, semantic macro retrieval, and theory graph navigation.
