Subject: [Fwd: HK Govt XML Guide finalised]

The following announcement and specification should be of interest to UBL members.  The Hong Kong SAR Government's XML Schema Design and 
Management Guide is a customization of the UBL approach for use in Government-to-Government (or whole of government) exchanges.  

Of particular interest is their BIM [Business Information Modelling] methodology, which is "... based on industry good 
practices for data and schema standardization, including ISO 11179, Core Components Technical Specification (CCTS), and Universal Business 
Language (UBL), for construction of information models." 

Congratulations to Thomas and the team at CECID - I am sure they would appreciate feedback from other UBL members.

Dear Tim, Mark, and Jon,

You may want to share this news with the UBL TC. This project is like a 
sister project to UBL. ;-b

Dear UBL TC,

The Hong Kong SAR Government has finalized the XML Schema Design and 
Management Guide V1.0. Most of the changes on the draft are 
clarifications. On the other hand, a new type of entity called 
Externally Defined Entity is added to the schema design methodology for 
importing and associating external schemas to encode data elements, 
which are already well defined in some technical and indsutry standards. 
For example, one can import the W3C XML Signature schema and create an 
Externally Defined Entity to encode a digital signature which is defined 
by the external XML Signature schema. Another example is: one can use 
XHTML to specify the product description by creating an Externally 
Defined Entity associated with the XHTML schema.

HKSARG XML Schema Design and Management Guide is available at:


Besides, our Government has also set up a Central Registry to manage our 
Common Schemas at:


At the moment, the Registry is still quite primitive. It will 
potentially be revamped in future when there is a stronger demand in 
using the Registry, e.g. more Common Schemas to be managed, and more XML 
projects to be shared among agencies.

Please feel free to give us comment to improve our work.
