Plone Software Center is a tool to keep track of software projects and software releases, and is used to power the Products download area on

It was formerly called ArchPackage.


To install Products.PloneSoftwareCenter into the global Python environment (or a workingenv), using a traditional Zope 2 instance, you can do this:

  • When you’re reading this you have probably already run easy_install Products.PloneSoftwareCenter. Find out how to install setuptools (and EasyInstall) here:

  • If you are using Zope 2.9 (not 2.10), get pythonproducts at and install it via:

    python install --home /path/to/instance

    into your Zope instance.

  • Create a file called Products.PloneSoftwareCenter-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

    <include package="Products.PloneSoftwareCenter" />

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

  • Add Products.PloneSoftwareCenter to the list of eggs to install, e.g.:

    eggs =
  • Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

    recipe = plone.recipe.zope2instance
    zcml =
  • Re-run buildout, e.g. with:

    $ ./bin/buildout

You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.

Because its top level Python namespace package is called Products, this package can also be installed in Zope 2 as an old style Zope 2 Product.

For that, move (or symlink) the PloneSoftwareCenter folder of this project (Products.PloneSoftwareCenter/Products/PloneSoftwareCenter) into the Products directory of the Zope instance it has to be installed for, and restart the server.

You can also skip the ZCML slug if you install this package the Zope 2 Product way.

  • Don’t wipe out list of allowable contained types within a PSCProject when PSC is reinstalled. [davisagli]

  • added a migration step to synchronize projects with PyPI. [tarek]

  • fixed a gs bug: propertiestool.xml now uses purge:False [mr_savage]

  • now adds ‘mailto:’ to contact address on uploads [tarek]

  • now adds ‘mailto:’ to contact address on uploads. [tarek]

  • introduced a deprecation warning for the simple view. [tarek]

  • Moved content/ to (with deprecation) as otherwise the registering of validators was too late due to the order of imports. [maurits]

  • Added Products.ArchAddon, Products.AddRemoveWidget and Products.DataGridField to the install_requires in [maurits]

  • added a pluggable storage mechanism for downloadable files. This can be used to define new storage strategies in independant packages. They will then be available in PloneSoftwareCenter instances, under the new “storage strategy” field.

    PSC provides a default strategy called archetype that uses a regular ZODB persistency.

    Other strategies are available like collective.psc.externalstorage. [tarek]

1.5 (2008-04-27)

  • Made the workflow of releases aware of development tags created by distutils so if an egg has “dev” or an SVN revision it is marked as an alpha. Various tidying of display to handle multiple eggs. Switched from CHANGES.txt and CONTRIBUTORS.txt to docs/HISTORY.txt [MatthewWilkes]

  • Refactoring multiple eggs in one project started by Tarek, added validators. [MatthewWilkes]

  • Support for multiple eggs in one project [tarek]

  • Refactored long_description and reorganized text files. [tarek]

  • PyPI integration, from an initial branch started by Sidnei, refactoring, beautification: [tarek]

  • Development, Maintenance: [aclark]
