|
|
|
|
u |
many
flavours of instances (as much as we have process steps?)
|
|
|
u |
occurance
cannot finally be checked by SGML/XML parser
|

Different
data is generated in different process steps
|
|
|
|

Not
all objects exist along the process chain

u |
handle
broken links
|
|
|
|
u |
establish
links automatically by knowing the semantics
|
|
|
|
u |
convert
to standard SGML style for exchange
|
|
|
u |
Global
data models of tools or processes must be mappeded
|
|
|
|
u |
export
capabilities are determined by the internal data model
|
|
|
|
u |
allow
multiple global data models
|
