<br><font size=2 face="sans-serif">Before our PWG Process document conference
call, tomorrow (10AM PST, 1PM EST) I would like to surface three new topics
which have recently come up.</font>
<br>
<br><font size=2 face="sans-serif">1. Use and adaptability of PWG schemas
in commercial products. </font>
<br>
<br><font size=2 face="sans-serif"> In the past, we have produced
mainly specification or best practices type documents which retain the
PWG copyright. These standards specifications are used as reference in
developing commercial products but the documents are not, themselves, directly
incorporated into a product. With XML schemas (and MIBs for that matter)
the copyrighted material may be incorporated directly within a product
and/or may be extended to obtain derivative works. I know it is our intention
that MIBs and PWG schema be used, freely, in this manner... but do we need
to make this more explicit in our process documentation or within the schema
themselves?</font>
<br>
<br><font size=2 face="sans-serif">2. Inclusion of a separate Semantic
Model section within the PWG Process document. </font>
<br>
<br><font size=2 face="sans-serif"> It might be more effective
if we remove the (newly added) SM chapter to a separate document. As important
as SM is to PWG, it dilutes the overall process document to highlight one
specific effort separately. Also, in breaking it out, we can do a better
job of addressing other SM topics such as limits to dynamic access and
copyright. </font>
<br>
<br><font size=2 face="sans-serif">3. Common handling of PWG schema. </font>
<br>
<br><font size=2 face="sans-serif"> As the Semantic Model
and its associated schema become widely adopted and leveraged by other
standards organizations, we need a formal mechanism for managing our schema
through the development phase and into some final durable form and location.
We need to respond to this quickly to support the FSG Japan group and their
use of our WBMM (Printer MIB derived) schema. The process needs to address
not only schema development and directory structure but also schema validation
and verification. </font>
