Version 4.9 brings you a whole new module to register Comic Books. It is supported by the invaluable online source that is

I have not yet created a DMG for MacOS, I am planning on creation and uploading this package, as part of this release, within the next few days.


- Data Crow synchronization service for external (to Data Crow) devices. This service allows both module and data to be synchronized. At the current stage, it's a one way synchronization going from Data Crow to the external device. This is the build up for something great(er) in the near future.

- New module: comic books.

- New online search for comics: Comic Vine

- New online search for comic book characters: Comic Vine


- NPE exception during the set up of the user folder due to the logger not having been initialized yet. This issue will hide the real underlying issue.

- Fixed an error on startup for MacOS (from the terminal).

- Fixed an error on startup for OpenJDK.

- Items not described correctly for none standard modules.

- Icon not showing for the shortcut created on Linux.

- Uniqueness check not working correctly if one of the fields is a key field but not a required field.

- The online search breaks the uniqueness check, causing duplicate items to be added.

- Clear on online search form did not clear the quick view panel.

- References field, selection dialog, did not adhere to "descriptive" setting of the module.

- Now if you supply credentials when creating a new Data Crow instance, Data Crow will create a user with these credentials. This is true for both the client and the server edition if the parameter -credentials has been supplied (see:

- Mass update for board games was not working.

- Mass update incorrectly causing warnings on item uniqueness.

- Mass update for books did not correctly check on the ISBN field.


- Internal structural changes have been made to allow the Data Crow core library to be incorporated in other applications. Most importantly the logging mechanism is now completely decoupled from the code as such that any other logging mechanism can be be used, suitable for the targeted platform. Other major changes have been made to significantly reduce the references to the AWT and Swing libraries (GUI) from the Data Crow core library. The exception to the latter are the image classes.

- The module wizard now allows you to create references to the same module multiple times.

- Removed setting: "delete picture file after adding it to an item"

- Report dialog now remembers selected target file per module and additionally also remembers the selected report and report format.


Data Crow is a free, open-source media cataloger and organizer, a multi-purpose tool that helps you to manage a massive amount of data in a single place.

It is powered by an intuitive, customizable user interface and has an impressive amount of features (see below). Although the program comes with a few, standard modules that allow you to organize your books, contacts, containers, images, media, music albums, software, users, there is no limit regarding the number of modules. Advanced users can create their module such as the one listed on the official homepage for "stamps": there is documentation available for those who wish to create their own module. The software is written in Java programming language by Robert Jan van der Waals (the author), and it works on Microsoft Windows®, Mac OS X®, and Linux.

Data Crow Review

Setup: Before attempting to install Data Crow, make sure that Java is installed; otherwise the installation will not continue (you will notice an error message: "Java Runtime Environment not found"). Please note that a portable version is also available.

Configuration: As soon as you install and start Data Crow, the "Tool Select Wizard" window will appear with the following message: "Data Crow is divided in modules, such as the software and movie module. Each module has specific tools, such as the online search, that can be used. In this step, you have to select the module for which you would like to use a tool."

A second window will show you how to add or create a new item. The "Tool Select Wizard" prompt window is enabled by default and will appear each time you open the software interface. However, you can easily disable this by unchecking the "Run on Startup" box.

Using Data Crow: When you open the program for the first time, you might feel a little intimidated by its rich user interface. There's a ton of options, and you quickly realize that customization is indeed one of its strongest points.

Play with it: As dumb as it sounds, each time I try a complex tool such as this one, I always try to use almost everything. For instance, what I did was to try the "default" modules by adding a new item to each module, tested the "Find and replace" filter, browse the "Settings" section, used the "Create a report" option, used the "Backup and Restore" function, tried the "Online Search" using IMDB and so on.

If you get stuck, feel intimidated or want to learn more, try the "Help" section (or press F1 from its interface) and you should be able to find a crystal clear answer. The help section is one of the best structured I have ever seen so, kudos for it!

When you get more familiar with the program, feel free to use it as your permanent cataloger/organizer, but please note that is extremely important to learn how to back up your data (just in case that something terrible happens - you don't want to lose your collection). There is a "Backup and Restore" feature in the "Tools" section so make sure that you use it regularly.

Just a few thoughts: I went online and searched for other people's opinions. Some people say that there's a small disadvantage (nothing major) because the program is developed in Java but hey, Java is almost everywhere and the program, at least on my laptop runs like a charm. When I used the online search feature, the program "downloaded" the data from IMDB a little slow but this is probably related to my Internet Connection or the IMDB servers which perhaps has a limit on the number of queries.

I also noticed an interesting comment saying that we manage our stuff using all kind of tools such as iTunes, Calibre, Ant Movie Catalog and so on. Data Crow doesn't have all the features found on other apps, but this has nothing to do with the current program capabilities.

My personal opinion is that the program was designed to help people gather their data in one place and quit using a separated movie, audio or book manager. Probably a good idea would be to allow the program to launch other 3rd party apps such as an audio/multimedia player when someone is browsing his (module) collection.

Conclusion: I love the program, and it was fun to play with and learn more about it. The concept is unique and offers one of the best solutions for those who enjoy the idea of creating an extensive database that can be accessed from a single place.
