Model (DSL model)
A "Telosys model" is a model based on a set of text files written with the Telosys "Domain Specific Language". The Telosys DSL uses a very simple grammar to define entities with their attributes and relationships.
To create a model see : Model creation
Since Telosys version 4.0 there is only one type of model: the DSL model.
In version 4.0, the DSL model has evolved in terms of structure and syntax.
The model parser has been completely rewritten, it has more consistency and syntax checks.
For example, the unnecessary comma between annotations is now prohibited and each annotation has a specific scope defining where it can be used or not (level : entity, attribute or link).
In short, the parser is now stricter and some entities may need to be modified to comply with the new rules.
Model structure since version 4.0
Since version 4.0 each model is a directory located in "TelosysTools/models".
Directory name is model name.
A model directory contains
a file "model.yaml"
n files ".entity" (1 for each entity)
Example : model "employees"
Model structure before version 4.0 (deprecated)
A model is composed of a ".model" file and a folder that contains all the entities (e.g. for a model named "foo" : "foo.model" file and "foo_model" folder).
Each entity is defined in a text file having the ".entity" extension (e.g. "Car" is defined in "Car.entity").
Example : model "employees"
