Core Software Group focuses it's efforts on developing content management systems (CMS) that are based on, and revolve around three core, open source, related frameworks: Zope, CMF, and Plone.

We have centered our development and integration efforts on these three frameworks since the year 2000, and believe them to be wildly powerful for delivering a range of services.

Tell me more about these frameworks

Plone (http://www.plone.org) is a very powerful open source content management system (CMS) that runs on many platforms, and includes some of the following features:

• No licensing costs--open source
  
• WYSIWYG editor for managing pages/content
• A clean, out of the box user interface, plus the ability to create templates for custom look and feel and page layout
• Role based permissions and membership tools
• Membership management - allowing for easy, clean, visitor  self-registration, and for admins to manage login information for various types of users and types of applications, such as content managers, site members, extranet clients, etc.
• Workflow based content -- allowing for private, draft, and published content based on business rules and user roles, plus the ability to generate your own workflow definitions based on business logic
• Built-in support for managing multi-lingual content
• A catalog to allow for searching of all content
• Many add-on products, such as Newsletters, Blogs, Calendars, etc.
• Much, much, more...

CMF (http://wiki.zope.org/zope2/CMF) is a collection of tools and services that together provide a basis for a content management system.  CMF provides the core infrastructure for performing the following tasks:

• Workflow based content management
• Role based permissions
• Site skinning capabilities

Zope (http://www.zope.org) is a Python based application server.

From zope.org:

"Zope is an open source web application server primarily written in the Python programming language. It features a transactional object database which can store not only content and custom data, but also dynamic HTML templates, scripts, a search engine, and relational database (RDBMS) connections and code. It features a strong through-the-web development model, allowing you to update your web site from anywhere in the world."

Zope uses a technology called Page Templates (http://wiki.zope.org/zope2/PageTemplates) to define the template(s) for a page.  Page Templates brings together markup and Python to provide for a powerful templating architecture.

Where does your project fit?

We believe there are different types of web projects and applications that fit into the above three frameworks.  Each framework has it's own strengths that apply to different projects.  Please contact us if you wish to discuss your project to see what the best fit is for you.
