We present a solution with a markup method that allows to label parts of a 3D object in a similar way to labeling parts of a hypertext. A 3D-markup can serve both as hyperlink and as link anchor, which is the key to bi-directional linking between 3D objects and web documents. Our focus is on a sustainable 3D software infrastructure for application scenarios ranging from e-mail and internet over authoring and browsing semantic networks to interactive museum presentations. We demonstrate the workflow and the effectiveness of our tools by re-doing the Arrigo 3D showcase. We are working towards a 'best practice' example for information modeling in cultural heritage.Categories and Subject Descriptors (according to ACM CCS): I.3.4 [Graphics Utilities]: Graphics editors I.3.6 [Methodology and Techniques]: Languages,Standards
