<h2>Introduction</h2> | |
<p> | |
SCA Tools is a proposed sub-project under the top level project <a href="http://www.eclipse.org/stp/">Eclipse SOA Tools Platform (STP)</a>. | |
</p> | |
<p> | |
This proposal is in the <a href="http://www.eclipse.org/projects/dev_process/development_process.php#6_2_2_Proposal">Project Proposal Phase</a> (as defined | |
in the <a href="http://www.eclipse.org/projects/dev_process/development_process.php">Eclipse Development Process</a> document) and is | |
written to declare the intent and scope of the SCA Tools sub-project. This | |
proposal is written to solicit additional participation and input | |
from the Eclipse community. You are invited to comment on and | |
join the project. Please send all feedback to the SCA Tools newsgroup (<a href="http://www.eclipse.org/newsportal/thread.php?group=eclipse.stp.sca-tools">http://www.eclipse.org/newsportal/thread.php?group=eclipse.stp.sca-tools</a>). | |
</p> | |
<h2>Background</h2> | |
<p> | |
The mission of the <a href="http://www.eclipse.org/stp/">STP project</a> is to build frameworks and extensible tools that enable the design, configuration, assembly, deployment, monitoring, and management of software designed around a Service Oriented Architecture. The project is guided by the values of transparency, extensibility, vendor neutrality, community collaboration, agile development, and standards-based innovation. | |
</p> | |
<p> | |
Currently, <a href="http://www.eclipse.org/stp/">STP project</a> contains a component named <a href="http://www.eclipse.org/stp/sca/index.php">STP/SCA</a>. Among other things, this component provides a graphical designer, named <a href="http://wiki.eclipse.org/STP/SCA_Component#Overview">SCA Composite Designer</a>, which allows to construct SCA assembly files. This tool is based on <a href="http://www.eclipse.org/gmf/">GMF</a> and works with an <a href="http://www.eclipse.org/emf">EMF</a> meta model constructed from the <a href="http://www.osoa.org/display/Main/Service+Component+Architecture+Specifications">SCA specifications version 1.0</a> proposed by the <a href="http://www.osoa.org/display/Main/Home">Open SOA consortium</a>. | |
</p> | |
<p> | |
The aim of this proposal is to transform the actual <a href="http://www.eclipse.org/stp/sca/index.php">STP/SCA</a> component into a sub-project of <a href="http://www.eclipse.org/stp/">STP project</a> and to add several other SCA tools. | |
</p> | |
<h2>Description</h2> | |
<p> | |
The purpose of the Eclipse SCA Tools sub-project is to develop a set of tools to help developers of SCA applications (like the SCA meta model, editors and a graphical designer which allows to construct SCA assembly files). | |
</p> | |
<p> | |
Our goals are also to link these SCA tools with existing Eclipse tools that can fit some aspects of the SCA specifications like the components <a href="http://www.eclipse.org/stp/policy/index.php">STP Policy Editor</a> and <a href="http://www.eclipse.org/stp/sc/">STP Service Creation</a>. SCA tools will also interact with the <a href="http://www.eclipse.org/stp/im/index.php">STP Intermediate Model</a> component. | |
</p> | |
<h2>Project Scope</h2> | |
The SCA Tools sub-project will focus on tools covering the SCA specifications proposed by the Open SOA consortium: | |
<ul> | |
<li> SCA ecore meta model corresponding to the XSD scheme proposed by the Open SOA consortium,</li> | |
<li> Ecore meta models of additional implementations, interfaces, and bindings defined by the SCA runtime implementations Tuscany, Frascati, and Fabric3,</li> | |
<li> Editors (XML, form, graphical) helping developpers to construct SCA assembly files,</li> | |
<li> Tools that introspect existing code to complete the SCA model according to SCA annotations found in the code.</li> | |
</ul> | |
<h2>Out of Scope</h2> | |
Somethings are not in the scope of the SCA Tools sub-project. In particular some aspects of the Open SOA specifications that are already covered by existing components of the STP project : | |
<ul> | |
<li> Deployment aspect (covered by the SOAS component),</li> | |
<li> Tool to assist developpers in the definition of SCA annotations in Java code (covered by the SC component),</li> | |
<li> Model transformations between SCA and other technologies (covered by the IM component).</li> | |
</ul> | |
<h2>Proposed Components</h2> | |
<ul> | |
<li> <a href="http://wiki.eclipse.org/STP/SCA_Component/SCA_Composite_Meta_Model"><b>SCA Domain Model</b></a> (existing code in STP/SCA component). This component contains the EMF meta model based on the SCA specifications version 1.0 proposed by the <a href="http://www.osoa.org/display/Main/Home">Open SOA consortium</a>. This meta model will serve as the basis for many tools. This component contains also additional validation rules that appear in the SCA specifications document (<a href="http://www.osoa.org/download/attachments/35/SCA_AssemblyModel_V100.pdf?version=1">SCA Assembly Model V1.00</a>) and that are not checked by the EMF meta model implementation. These rules are listed <a href="http://wiki.eclipse.org/STP/SCA_Component/SCA_Composite_Meta_Model#Additional_validation_rules">here</a>. These rules will be implemented using the <a href="http://www.eclipse.org/modeling/emf/?project=validation#validation">EMF Validation Framework</a>. This component can be use in an Eclipse environment or standalone.</li> | |
<li> <b>SCA Integration</b>. This component will contain all plugins that implement integration with other STP tools in relation with SCA: STP Policy Editor, STP Service Creation, STP SOA System.</li> | |
<li> <a href="http://wiki.eclipse.org/STP/SCA_Component/SCA_Composite_Designer"><b>SCA Composite Designer</b></a> (existing code in STP/SCA component): this component is a graphical (GMF) development environment for the construction of composite applications.</li> | |
<li> <a href="http://wiki.eclipse.org/STP/SCA_Component/SCA_Composite_Editors"><b>SCA Composite Editors</b></a>: this component will contain a source editor, a tree editor, an XML editor and a Form editor to construct SCA assembly files.</li> | |
</ul> | |
