1.
Standard engineering terminology is needed
- There is no standard electronic Business/Engineering dictionary available
Ecl@ss, Rosettanet, Trade Ranger, UNSPSC, ,
STEPlib / ISO 15926-4
All proprietary data and based on proprietary data models
2.
Data structures are problematic
- Data models are different and proprietary:
communication barriers
- Data models are domain specific:
e.g.
ISO 10303 (STEP), ISO 13584 (PLIB)
- Data models are inflexible, fixed patterns rather than a full language
3.
Generic standard data models are difficult to implement
- E.g.
ISO 10303-221 (AP221), ISO 15926-2
4.
XML does not provide standardization of application data
- Neither data modeling languages nor data models define application terms
- E.g.
UML, XML-schema, EXPRESS
