Introduction

This guide describes the conventions for working with EDL models.

Conventions

Model Files

Define every complex type (e.g. orm class, capi interface, ...) in its own *.edl file.
Store the *.edl files in a separate folder in the cartridge, e.g., in the edl folder.
Create a folder structure according to the namespace of the EDL types, like:
{cartridgename}/edl/com/intershop/beehive/core/capi/domain/ExtensibleObjectPO.edl

Formatting Conventions

Use 4 spaces instead of tabs.
Do not use special characters in comments (use plain english).
Use a coding style similar to the Java programming conventions, see Guide - Java Source Code Style Guide.

Naming Conventions

Use the suffix PO for ORM classes (stands for persistent object).

Order of Elements

Arrange the members of a class in the following order, from top to bottom:

Contraints: primary key, alternate key, semantic key, index declarations
Attributes: all attributes
Relations: all relations
Operations: all operations

Note

The order of attributes and relations matters. This is important for the generated code in several places, like the order of mandatory parameters in the create-methods of ORM factories.
