Designing Services, Messages and Rules for eBusiness

 NSW Land & Property Information (formerly the Land & Property Management Authority of the NSW Department of Lands) has been developing services to be provided by the NSW Land Registry for:

·      the electronic lodgment and registration of Land and Property transactions

·      the supply of Land Title information to interested parties.

The speaker headed a team that developed, in a volatile environment of changing requirements:

·      detailed conceptual models for the XML schemas for all messages to and from those services

·      the rules (in a controlled natural language developed for the purpose) governing the Registry Instruments and Information Reports that document Land and Property transactions

·      a BPMN model of the processes by which those Instruments and Reports are validated

·      data representation standards

·      the format of compliance reports generated by the above services.

This case study reviews:

·      the techniques used for converting requirements to sound designs

·      the standards used for the various design documents

·      the impact of frequent changes to an interlinked set of designs

·      the challenges faced by the team, and the means employed to deal with those challenges.
