christian.neubert@in.tum.de Motivation Enterprise architecture management (EAM) is a challenging task, modern enterprises have to face. This task is often addressed via heavy-weight and expensive EAM tools to collect, structure, visualize and analyze architectural information. A major problem in EAM is the mismatch between the existing unstructured information sources and the rigid information structures and collaboration mechanisms provided by today's EAM tools. To address this mismatch,

... chers at Technische Universität München established in 2010 a community of experienced enterprise architects from 25 large German enterprises to pursue a different, wiki-based approach to EAM [3]. The idea is to start with existing unstructured information sources captured as wiki pages (e.g., derived from Office documents) and then to incrementally and collaboratively enrich the wiki pages with attributes, types and integrity rules as needed for architecture modeling, visualization and analysis [1]. An off-the shelf commercial enterprise wiki (Tricia by infoAsset AG [4]) provides the required incremental information structuring capabilities as so-called Hybrid Wikis. Customizable in-browser visualizations are provided by the System Cartography Tool developed at Technische Universität München [2]. Demo Outline Architectural information (in anonymized form) from the Wiki4EAM community members will be used to demonstrate typical EAM use-cases using Hybrid Wikis:  Full-text and structured search, tagging, linking, input completion, WYSIWYG editing, discretionary and rolebased access control.  Incremental (emergent) information structuring with attributes, formats, types, cardinality constraints, and consistency rules with a user interface accessible to business users.  Customizable generation of in-browser visualizations (cluster maps, matrix maps and graph layouts) based on structured query results.  Import of and integration with existing architecturerelevant information sources (Office documents, files, databases) in the enterprise.  Open access to architectural information (file export, REST API). Expected Benefits for the Audience  Hands-on and practical information on the use of (semantic) wikis for strategic IT management.  Experience and challenge a new enterprise wiki with an innovative approach to capture emergent information structures.
