Printed newspapers in India are encouraging Citizen Journalism where readers  contribute to the columns with social and civic issues, eye-opening photography and touching true experiences and stories.

The approach works wonders as it allows reporting of news right from the true source of its creation. It also reduces the load on official reporters and encourages collaboration with the common man. Typically, 5-10 percent of print seem to be originating in the hands of readers these days.

Express JSON as Database Table from Enterprise Data Mashup

Project Mural offers an option to express data output from Enterprise Data Mashup (EDM) Service as JSON (Java Script Object Notation).

While JSON naturally gels well with the Java Scripts, there might be a requirement to process JSON with Java Utilities.


Here is a Java based JSON Parser for Project Mural Data Mashup Service that can help you do the following :

  • Visualize your JSON output from Data Mashup service more legibly as well laid table.
  • Convert JSON output into String table that can be viewed as a table into a different platform say, Mobile or a Handheld device.
  • Create Axion Database Tables with JSON data. Later use this to export data into some other database or use this into another Mashup.

You can download the JSON Viewer and the Source Code for this utility and here is how you can use it.

  1. Download and Unzip
  2. From MuralDataMashupViewer, Execute the Main class as follows
  3. Execute one of the following commands. Set your java path if not already done.
  • java-jar JsonFromMashup.jar <Data Mashup Service URL>
  • java-jar JsonFromMashup.jar <Data Mashup Service URL> <DBName> <DBPath>


<Data Mashup Service URL> : URL of your running Data Mashup Service (refer)

<DBName> : Name of the Database to be created containing JSON table

<DBPath> : Absolute path of the location where database needs to be created.

While the former expresses the JSON from service as a table on your output screen, latter also creates a database with JSON data from service that can be user with any other application. The screen shot shows JSON table created in NetBeans DataView abut JSON table expression on the user window.

Get your hands dirty with Mural Hands-On-Lab

Project Mural comprehensive suite bundles components that must inter-work to help user build a functional Master Data Management (MDM) solutions.

Following are the set of core components bundled in the suite :

Being the first open source community focused on MDM, it offers participative platform for the community based development and also encourages contributions in terms of pragmatic MDM solutions based on Mural technologies.

If you wish to take a deep dive into how some of these components can build a MDM solution for you, here is the place to start ....

Mural Hands-On-Lab starts from pulling out the data from a data source and transforming/loading it to a staging area using data integrator. It also shows how a simple master index model can be build that could consume the data from the staging. The lab also highlights how cleanser and profiler can be used on the source data before it could be processed to generate indexed database.

Note that the lab content is based on current implementations. As the components are rapidly evolving, the lab content may need upgrades which will be done in the phased manner.

The hands-on-lab zip can be downloaded here.

Rich set of Mural documentation and training tutorials are also available for a quick start.

Mural Installers can be downloaded from here.
