DEX Development Process

Overall DEX development Process.

Figure 1 - DEX Development Process

Request Development

Send a request to the organization of person responsible for the intended context of the DEX. Investigate if the business needs are covered or partly covered by existing DEXs. Also, investigate if the business needs are supported by the model (c.f. the models capabilities).

Initiate Development

Initiate the DEX development, select editors, and reviewers.

Develop DEX specification

Specify how to use PLCS to support data exchange.

Composite Diagram: Develop DEX Specification

Domain Expert Review

In the end of the development phase, the output DEX (Specifications, Templates and associated Reference Data) must be reviewed to make sure it fulfills its purpose and have the desired quality.

Community Review

OASIS review. General templates developed in the OASIS must be reviewed by the OASIS TC before the DEX may be published.

Publish DEX

PLCSlib is published as a web document in the form of a collection of HTML pages.

Develop DEX Specification

Specify how to use PLCS to support data exchange (appears in DEX Development Process).

Figure 2 - Develop DEX Specification

Describe Business and Information Scope

Describe the scope, the business process, and the information requirements to provide a clear understanding of the context for the exchanges.

Define DEX

Define how to use PLCS to support data exchange using the business information model of the preceding activity as input.

Generate XML Schemas

Generate an XML Schema file limited to the sub-set of PLCS PSM blocks used by the DEX specification.

Create Test Data

Create a fully populated test data file for the DEX.

Describe Business and Information Scope

Describe the scope, the business process, and the information requirements to provide a clear understanding of the context for the exchanges (appears in Develop DEX Specification).

Describe the business scope

Describe the scope in order co clearly bound the exchange requirements. and related processes.

Describe the business process

Describe the business process to provide clear understanding of the context for the exchange(s).

Describe the business information requirements

Create a business information model, defining the information requirements, using standard notations such as UML and SYSML. The model should be developed using terminology appropriate for the business context.

Create Test Data

Create a fully populated test data file for the DEX.

Define DEX

Define how to use PLCS to support data exchange using the business information model of the preceding activity as input (appears in Develop DEX Specification).

Setup Context

Setup a “container” for the DEX classes and vocabulary, if no appropriate context already exists.

Develop Templates

Define the mapping of the business objects to PLCS.

Composite Diagram: Develop Templates

Develop Reference Data

Define how the semantics of the PSM are extended to support the DEX.

Develop Block Diagrams

Create block diagrams to explain how the templates are used in the DEX.

Develop Templates

Define the mapping of the business objects to PLCS (appears in Define DEX).

Figure 5 - Develop Templates

Identify which templates are needed

Identify already existing templates from OASIS, and templates that have to be created.

Develop business templates

Prepare for the template in PLCSlib, create the SysML for it and document the template.

Develop standard templates

Prepare for the template in PLCSlib, create the SysML for it and document the template.

Develop Reference Data

Define how the semantics of the PSM are extended to support the DEX (appears in Define DEX).

Create RD Library

Create a context specific RD library if it doesn’t exist already.

Related Documentation: Reference Data development

Develop Classes and Individuals

Extend the core OASIS standard reference data concepts to cover these context specific concepts of the DEX being defined.

Add language extensions

Add parallel RD files to support different languages where appropriate.

Version control library and classes

Add meta-data annotation to the library and classes e.g. revision information on the file and status on the classes and individuals.
