Subject: HKSARG XML Guide

Dear Mark,

This is Thomas Lee from CECID Hong Kong. I had an ATG2 teleconference 
with you on April 7. I mentioned about an XML Schema Design and 
Management Guide we have been developing for the Hong Kong SAR 
Government (HKSARG). We've just finished a DRAFT version as attached and 
would like to seek comments from your group.

The attachment is packaged as follows:

Part 1 - Overview: an introduction to the objectives of this project and 
the deliverables.
Part 2 - XML Schema Design Guide: an XML Schema design methodology we 
have produced based on CCTS and UBL. It is intended to standardize the 
mechanisms for producing XML Schemas for HKSARG G2G and G2B joined-up 
Part 3 - XML Schema Management Guide: the policy and organization we 
propose to manage and standardize the XML Schemas produced by different 
government departments.
Part 4 - Appendices: supplementary information for applying the Guide, 
including a case study for illustrating the use of the Design Guide.

I would like to add a point that the way of standardizing schemas for 
HKSARG is quite different from the ways commonly used by other standards 
bodies, such as ATG2 and UBL. We have adopted a rather decentralized and 
progressive approach for HKSARG, in which schema components to be 
standardized are contributed by projects. HKSARG does not intend to 
standardize schemas at the document level (at least initially) while it 
seeks to standardize only essential schema components, such as different 
types of addresses (e.g. postal address, physical address, etc.).  The 
reason is partly due to that this progressive approach is strategically 
more feasible than the big bang approach for standardization because of 
the decentralized IT management nature in HKSARG.

Therefore, we choose to provide a simple standard methodology for 
project teams to capture buisness requirements and translate them into 
consistent schema code. We have extensively simplified and systematized 
CCTS for project teams, who are not expected to be XML and 
standardization experts, to use. A very small central team will be 
formed to standardize only essential schema components of which the 
business requirements are contributed by project teams. Owing to the 
extensive customization, we seek to remove and modify some complex CCTS 
concepts and features. Therefore, some potential deviations from CCTS 
should be expected.

I believe your team could provide us with valuable suggestions on 
further enhancing our deliverables with your XML standardization 
experience and expertise. On the other hand, you may also see whether 
some guidelines in the Guide are relevant for adoption by your team. You 
may upload this package to your e-room for review by your members.

Dear Jon,

I would like to see if the UBL team is also interested in this XML 
Guide. BTW, we have adopted many ideas from the UBL methodology. :-) 
Please also circulate the package among your members. We would like to 
invite comments from your team too.
