Subject: FWD: Re: [egov] XML Schema Design and Management Guide for Hong Kong SAR Government
Team, Just wanted to let you know that following interchange has developed on the eGov list with regard to CAM and the HK Gov use of XML schema. I plan to respond to this early next week, and pick up the theme for simplicity and end user access. There's some ideas I think Thomas should be thinking about that he's not already mentioned. Clearly they need two documents - one is their technical guide (the current doc'), and another which is a Primer. Of course I'm encouraged, and yet again reminded that we do need to move forward our spec's to official status, so I will be looking to have a 0.14 draft available before the end of July. Feel free to send me feedback that would make sense to pass along to the eGov team too. Thanks, DW. -------------Forwarded Message----------------- From: INTERNET:ytlee@cecid.hku.hk, INTERNET:ytlee@cecid.hku.hk To: , INTERNET:egov@lists.oasis-open.org Date: 7/19/2003 1:10 AM RE: Re: [egov] XML Schema Design and Management Guide for Hong Kong SAR Government Dear David and eGov TC, I previously sent the following response to the mailing list yet it happened to me the message didn't reach the list. Let me re-send the message to you as follows: ----- Thank you for your advice. I have briefly gone through some CAM materials, which are definitely very valuable resources. I forgot to mention in my previous email that the XML Guide is a live document, which will be reviewed and updated every six months. Therefore, when CAM becomes mature and gains good software support, the XML Coordination Group of our Government will definitely consider adopting it in an appropriate way. My team will also further study the materials in depth in the coming months to see if the XML Guide is ready to adopt any CAM features. Yet as I mentioned in my email to ATG2 and UBL, we have some constraints in developing this Guide at the current stage: 1. XML Schema is an approved standard in the current version the HKSARG Interoperability Framework. So the XML Guide must be a design methodology for XML Schema. 2. The Guide must be as simple as possible to gain the initial acceptance by the Government and the industry. XML technology is still quite new to our Government and the IT industry in Hong Kong. Besides, the users of the Guide are not standardization experts. They are mostly non-technical business users from Government departments and system developers from IT contractors. Therefore, it cannot be too complex for them to understand and use. That’s why we have paid so much effort to simplify CCTS. Besides, it should be possible to streamline the methodology by software in short term. We are developing software tools for capturing the business requirements and translating them into XML Schema code according to the methodology. Now, some Excel macros and program scripts have been developed for simple XML Schema code generation. 3. We are aware of the current limitations of the Guide. We understand it is not a total solution for information interoperability. However, if the Guide is only expected for non-technical users to produce consistent schemas, it seems to work. It is a strategy that we try to promote users’ the technical understanding and development on XML through the Guide. After they have picked up the skills, we believe they will expect more. It is easier for us to introduce more advanced features, such as CAM for XML standardization. (You are perfectly right. At least three address schemas have already been identified. Now, we simply develop three separate schemas rather than using the context driven approach. The data constraints that cannot be expressed by XML Schema will be specified by a supplementary textual implementation guide.) I quote the email I sent to ATG2 and UBL again to give you more background on the formulation of the XML Guide. Thanks again for your suggestions. My team will study and consider the CAM technology carefully and make appropriate recommendations to our Government team. Regards, Thomas ================================================================== Date: Tue, 17 Jun 2003 13:07:06 +0800 From: Thomas Lee <ytlee@cecid.hku.hk> To: MCRAWFORD@lmi.org CC: jon.bosak@sun.com, "H.Sugamata" <sugamata@ecom.or.jp> 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 services. 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. Regards, Thomas -- Thomas Y.T.
