  1. Technical Aspects of I++DMS

  2. Typical Interfaces along Product Development Chain / QA Specialization and optimization on specific contents; parametric-associative information hardly representable. • Effects on Quality Assurance • CAD Information gets lost for downstream processes (features, tolerances, material thickness …) • Maintenance and change effort • No free choice in software and hardware • No comparability of inspection results. • Proprietary exchange formats problematic for SW-vendors. several interfaces in parallel 100110 Planing Programming file-based SS2 SS1 CAD SS5 SS3 Semantics not synchronized Offline Analysis Executing SS4 many proprietary interfaces

  3. The I++DMS Information Space Goal: One information space; all application are contributing to and utilizing according to their needs. Planing Programming Global Information Space »GIS« CAD Offline Analysis Executing

  4. The I++DMS Information Space – Motivation • Dynamic of information.→ GIS is extendable; the service-based communication interface is extendable; exchange format is stable. • Relationships are essential → Inside the GIS, information is tightly correlated. Semantics through holistic viewpoint. • Transparency: intellectual property must not drain away inside software applications. → GIS meta level; I++ information model in the center.

  6. Key Properties of I++DMS • Scalability: flexible applicability in multiple expansion stages • Intensity: file-based vs. runtime communication • Range of information to be exchanged (sub-set of GIS information) • Exploitation of background knowledge (e.g. inspection strategies). • Openness: • Compatible to any S/W application • …for new information sets. • …for new functionality (services, see SOA) • …for new communication technologies (WebServices, CORBA).

  9. Effects of I++DMS GIS • one single global information space replaces multiple local interfaces. • Integrated information replaces information isles; Informational backbone. • Downstream applications may use hardly accessible information (↑CAD); Basis for sophisticated and highly-specialized software. • (the fine print): certain loss in efficiency by principle (rising universality and expressivity).

  10. The I++DMS Starter Kit • Free delivery by I++ OEMs to foster spreading of I++DMS • „Test bed“ and documentation, consisting of freely available components… • ULEOserver • source code examples • documentation I++ information model • documentation of underlying technology Universal Linking of Engineering Objects (ULEO). • Software service providers are offering technical supportand software development.
