Open eCom


What is Open eCom?

Open eCom is Java Open Source B2B Framework under development. Currently it contains implementation
of the following standard business documents according to GS1 eCom standard specification:

  • Order
  • Invoice
  • Despatch Advice
  • Receiving Advice
All of these classes have been automaticly generated from their coresponding XML Schemas using JAXB
(Java Architecture for XML Binding).From GS1 site : "GS1 eCom provides global standards for electronic
business messaging that allow rapid, efficient and accurate automatic electronic transmission of agreed
business data between trading partners."

Vision

The idea of this projects is to provide open source Java implementation of typical components used in B2B
applications, based on widely accepted standards. It should provide standard, ready to use business
documents and workflows used in B2B transactions, so developers can focus on application specific features
and business processes.


Main benefits of using Open eCom are:
 
  1. Faster development. Having ready to use and well documented data models created by industry experts,
    will significantly reduce time needed for requirement analysis and data modeling. This will also help to avoid
    a lot of repetitve work, and put focus on features that has real value to the customer. Important thing is not
    just having these in the form of specifications, but in the form of working implementation.

  2. Flexibility and extensibility. It is very likely that everything that clients may want in future is allready part of the
    standard, and it will require no modifications. However there is a standard way for extending existing documents
    using extensions feature.

  3. Better reusability of developed processes, since they will be based on the same documents.

  4. Full interoperability with other GS1 eCom systems which is widely accepted standard for business message interchange
