To enhance data interoperability in e-government services, project teams
are recommended to maximize the reuse of information models. One way to
enhance the reusability of information models is to conduct data alignment
concertedly for data elements that have potential for reuse across bureaux / departments (B/Ds).
This Registry of Data Standards facilitates access to the concertedly aligned data
elements, presented as information models together with the corresponding XML
schemas (collectively referred as Common Schemas).
Projects that use XML for data exchange may copy the relevant XML schemas
into their Project Registries for further refinement as Project Schemas.
For projects that use other message formats (such as UN/EDIFACT) for data
exchange, project teams are recommended to adopt the concertedly aligned
information models and bind them with the relevant message format.
For more information on XML Schema Design and Management, please refer to
the XML Schema Design and Management Guide promulgated on the HKSARG
Interoperability Framework Web Site
