EDAS2 is a free and open source project for the Web-based management, analysis, and exchange of environmental data. Owing to its desktop-based predecessor (History), EDAS2 will initially focus on water quality data, and more specifically aquatic biology and habitat data.

The goals of the project are as follow:

• Support environmental data management for individual small- to moderate-sized organizations
• Reduce barriers to entry - easy installation, ease of use, low/no cost to get started
• Provide core functions focused on managing environmental measurements
• Reduces costs for best-practice data management
• Facilitates recording data and metadata in a secure and standard fashion
• Increases opportunities for data exchange

The current version of EDAS2 is a Java-based Web-application and is supported by the Oracle database.

The technologies used in EDAS2 are the following:

• Redhat/Jboss Seam 2.0 J2EE Application Framework http://seamframework.org/
• Redhat/Jboss RichFaces 3.2.1 JSF Component Library http://www.jboss.org/jbossrichfaces/
• Oracle 10g Database Server

The Java system will be based on Seam as an application framework and will use JSF (RichFaces) for a UI toolkit. In addition to being a reasonable and flexible combination of technologies, it will allow the easy incorporation of the RichMap mapping component, which Tetra Tech also developed as an open source project.

Examples of RichFaces can be seen here http://chiralsoftware.com/richfaces-jboss-inplace-input/inplace-input-textarea.seam

The source code for EDAS2 will be at http://sourceforge.net/projects/edas2/ after the first official release (following the alpha releases)

Until then, development materials are available on request only

We will be iteratively producing a User Guide through this wiki

In addition to tracking bugs and enhancements through the EDAS2 Tracker at http://www.edas2.com/tracker , we will also describe Known Issues that are persistent. These are likely out of our control and may be due to items such as bugs with underlying technology like databases and application frameworks.

We will pursue fixes for these items, but we are unlikely to be able to address them as part of the project.

We are also running an internal testbed in a shared environment as in the diagram below. The testbed demonstrates flowing data between two systems.
