Distribution

Requirements

AToM3 requires Python 1.5.2 or above (although version 2.2 is strongly recommended). Python can by downloaded from the Python Language Website. AToM3 runs on any plataform supported by Python. This includes Unix and MS Windows.

Downloading the distribution

Note that you should dowload the latest version of AToM3 from Denis Dube's homepage


The old version (AToM3 2.2) is available here as a compressed archive (zipped, zipped tar, or gzipped tar file):

Installing the distribution

In Unix:

  1. Copy or move the downloaded file Atom3_2.2 in the target directory.
  2. Unzip the file, type: gunzip Atom3_2.2.tar.gz
  3. Untar the file, type: tar -xvf Atom3_2.2.tar

This will create a directory named Atom3_2.2 where you performed the previous operations.

In Windows: Use any decompressing tool that supports gzipped tar files such as WinZip.

Getting started

To run AToM3, you need to be on the directory created by the installation. Then type (under MS-Windows it is not recommended to run it from an MS-DOS prompt window; use Start|Run instead):

atom3

or, alternatively

python ATOM3.py

This will run AToM3 with the default meta-meta-model, which now is the Entity-Relationship formalism (future versions might replace this with UML).

To open with a different meta-model there are two options:

  1. On the command line, type: atom3 <meta-model-name> or, alternatively python ATOM3.py <meta-model-name>
  2. Browse through the directory structure by choosing the File|Open meta-model menu option.

To open an existing model, use the File|Open model menu option. This will automatically load the appropriate meta-model.
