gCube is a Software System whose development activity is ongoing and performed according to the Agile software development methodology. This implies that software components are developed in relatively short subsequent iterations, each containing the tasks needed to release new functionality - planning, requirement analysis, detailed design, implementation, integration, testing and documentation. This leads to a very flexible and dynamic development activity that needs to be proper documented.

This page documents the current status of the gCube system by presenting a series of statistics and metrics of its evolution including progression of source code over time, developers activity, and automatic build results.

Moreover, because of the distinguishing characteristics of gCore, a gCube constituent that is a system by its own, in the rest of this wiki the data of both these systems are separately presented.

Development Status

gCube has been designed by following the principles of Component-based software engineering, thus it consists of various software components interacting each other to implement the expected functionality.

The GCube Architecture section describes the resulting Reference Architecture, the main sub-systems (i.e. logical group of components), their constituents and their relationships.

The system has been implemented according to the Service Oriented Architecture principles and related standards while the Presentation-oriented components are based on portlets. It currently consists of:

• 50 Web Services;
• 11 Software Libraries;
• 19 Portlets.

The gCube Development Status Report presents detailed information about the current status of each component.

The GCube EMC Development Status Report presents more information on the current status of the components developed to capture the Environmental Monitoring Community requirements.

The status of gCore is captured by its latest release.

Code Statistics

D4Science uses StatSVN to retrieve information from the project software repository and to generate various tables and charts describing the project development. In particular, the following reports are available.

Automated Builds

D4Science relies on the ETICS system to automate the way its software (gCube and gCore) is built and tested. In particular, the project has put in place mechanisms to perform daily builds with the latest version of the code committed in the project software repository. This activity leads to the production of (i) a report of the build activity and (ii) a set of software artifacts including the software package, the source code and the documentation. These are available below.

Download

The release of the software is regulated by the project Integration, Testing and Distribution activity that aims at building a deployable, reliable and documented software distribution.

The final result of this activity is a set of gCube and gCore releases which are made available through the gCube and gCore Distribution Site.
