What this is about

As of release 1.3 Tuscany SCA is distributed via one binary distribution that includes everything. Based on user feedback, choice of a smaller distribution packages is desireable. Tuscany community is in the process of addressing this requirement. Please see mailing list for that discussion. This is not the purpose of this page.

Tuscany users have asked for a write-up that highlights module dependencies. This enables them to build their own distribution which may have a lower or higher granularity than the pre-packaged binary distributions. Purpose of this page is to help users understand how to build their own tuscany SCA light distribution based on module dependency knowledge that is shared here.

Therefore:
This page is not about building Tuscany building binary distributions to distribute
This page is about understanding dependencies so that users can build their own distribution

How to build your own distribution

Let's first understand the different categories of module types in Tuscany. This understanding will help us determine how to put the modules together to have a runnable and useful system.

Tuscany Modules Categorized

SCA programming Model: Assembly, Deployment, Management
SCA provides a programming model for Construction, Assembly, Deployment and Management of network of services. Modules under these catetories support the SCA programming model.

Tuscany Container
Modules in this category are specific to running SCA in a Tuscany environment.
Tuscany container also provides plug points for different host types, bindings, implementations, policies as well as deployment and management (contributions and domain handling).

Policy
Module in this category include support for enabling policies as well as policy types.

Binding
Modules in this category include various bindings that support different protocols. Typically Bindings are used with SCA programming model, Tuscany container and some component implementation types.

Implementation
Modules in this category include support for different component types. Basic SCA environment is needed to use any of these modules.

Host Environment
Modules in this category include support for different host environments, such as Tomcat, Jetty, etc.

Module Category Dependency

This section explains the dependencies amongst various categories. This information can be used to define the scope of modules needed to perform different tasks using Tuscany.

Category

Dependency

SCA Programming Model

None. It runs in any container

Tuscany Container

SCA Programming Model. Note that Tuscany Container has plug points for various host environments, but is not dependent on any.

policy

Tuscany Container and SCA PM

Binding

Tuscany Container and some host environment depending on the protocol type

Implementation

Tuscany Container

Tuscany Modules Break Down by Category

Note All modules that represent models are highlighted in green. A model out of a category can be used without dependency on the rest of the category. One use case may be tooling.
