<DIV><FONT face=Arial>Hello,</FONT></DIV>
<DIV><FONT face=Arial>We are involved in a SGML project and we are finalisizing
the analysis phase.</FONT></DIV>
<DIV><FONT face=Arial>At present we are thinking about how to implement the
management of loose-leaf pages updates because any availabe off-the-shelf
comercial implementation can cope with our needs.</FONT></DIV>
<DIV><FONT face=Arial>We think that the concept of architectural forms can help
to manage the processing the flow between the intial information structures
(SGML semantic tags ) and the presentational/layout structures of the final
pages.</FONT> </DIV>
<DIV><FONT face=Arial>As Rick Jelliffe said in a past discussion on XML-dev
DSSSL ( with the MIF/RTF backend for example) can help to do the
transformations to the the layout structures ( down-sizing), but we can't
obtain any feedback from the layout program to the stylesheet
language.</FONT></DIV>
<DIV><FONT face=Arial>We know that others programs as Omnimark or Balise can
help to down-size the SGML instances but we will need a flow of dependence
from the pages/layout to the original SGML.</FONT> </DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>A possible implemention of our system would be to build
three independent Databases:</FONT></DIV>
<DIV><FONT face=Arial></FONT><FONT color=#000000 face=Arial
size=2> <FONT size=3>- Information SGML
Database.</FONT></FONT></DIV>
<DIV><FONT color=#000000 face=Arial size=2><FONT
size=3></FONT> <FONT size=3>- Layout Database (Quark,
FrameMaker,...).</FONT></FONT></DIV>
<DIV><FONT color=#000000 face=Arial size=2><FONT
size=3></FONT> <FONT color=#000000>- <FONT size=3>Page Objects
Database ( PDF).</FONT></FONT></FONT></DIV>
<DIV><FONT color=#000000 face=Arial size=2><FONT color=#000000><FONT
size=3></FONT></FONT></FONT> </DIV>
<DIV><FONT color=#000000 face=Arial size=2><FONT color=#000000><FONT
size=3></FONT></FONT></FONT><FONT face=Arial>and a "meta-Database" to
manage all the "processing" an "relationships" between the
elements of each database. </FONT><FONT face=Arial>This
"meta-Database" would control and manage the workflow and updates of
the different elements.</FONT></DIV>
<DIV><FONT face=Arial>Can architectural forms model this meta-database schema to
control the three database from a top structure? Architectural forms can store
all the information about processing.</FONT></DIV>
<DIV><FONT face=Arial>How difficult would be to build a similar system
?</FONT> </DIV>
<DIV><FONT face=Arial>It will be necessary to define property sets and grove
plans for the Layout scheme and Page scheme, doesn't ? Is there any working
experience on this topic ? ( PDF, Quark, FrameMaker,...)</FONT> </DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Any feedack will be of great value for
us!</FONT> </DIV>
