- working with objects (resizing, moving, lowering, raising, etc.);
- grouping/ungrouping objects;
- headers/footers;
- advanced undo/redo;
- setting background (color, gradients, pictures, clip-arts, etc.);
- assigning effects for animating objects and defining effects for changing slides;
- playing screen presentations with effects;

PRES project (the Press Release System) is a simple content management system, essentially targeted at producing a news and information site. Managing a PRES system is designed to be simple.
However, presentation is sophisticated and flexible. An elementary knowledge of IT would be useful but expertise in designing and managing websites is not a requirement. PRES can be used for anything from private blogging to corporate news systems.
Main features:
Flexible Presentation
- All content is generated as XML which is styled at server side with XSL-T stylesheets to provide the final look and feel of your pages. This permits an almost infinite variety of presentations. Furthermore, different XSL-T transforms can be associated with different categories, allowing you to have different styling for different parts of your site.
Caching
- Content is generated on request, but in order to limit the computational load on busy sites all content is cached for a limited period (by default twenty minutes).
Subscription
- PRES allows users to subscribe to categories - effectively sections of the site. When new stories are posted to a section youre subscribed to, you will automatically get email with a link to the story.
Syndication
- PRES makes its headlines available as a syndication feed, using both RSS 0.91 and RSS 1.0. This allows other news sites to automatically incorporate live headlines from a PRES site into their content.
Threaded Discussion
- PRES optionally allows registered users to add comments to stories in a threaded manner, similar to sites like Slashdot.
Moderation
- PRES optionally allows registered users to moderate other users comments.

XMLPublication project is a collection of tools to generate Web pages from desktop documents or other structured documents, such as books with paragraphs, or tabular data.
It cuts documents into Web pages, and creates customizable multi-indices.
All this is done through a repeatable process in which data is separated from presentation and user settings. It uses XML techniques, particularly XSLT and Ant.
Enhancements:
- we used

tags, but switched to

Apache Forrest is a publishing framework that transforms input from various sources into a unified presentation in one or more output formats.

The modular and extensible plugin architecture is based on Apache Cocoon and relevant standards, which separates presentation from content.

Forrest can generate static documents, be used as a dynamic server, or be deployed by its automated facility.

Forrest is designed with the new user in mind. Much effort has gone into making the process of generating a new site easy and simple:

Step 1: Do forrest seed to populate the directory with template site structure and contents.
Step 2: Add content by editing docs in task-specific, presentation-neutral XML.
Step 3: Do forrest run then use the web browser to immediately review changes at http://localhost:8888/
Step 4: Do forrest to generate the complete website from the XML sources. Various styles (known as skins) are available. Custom skins can be developed.
Step 5: For more information about installation and use, see the Using Forrest guide.

Forrests focus on low "startup cost" makes it ideal for rapid development of small sites, where time and budget constraints do not allow time-wasting HTML experiments. Of course, that same methodology can scale up to large projects. Your development team does not need Java experience, or even XML skills, to use Forrest. The framework lets you concentrate on content and design.

By separating content from presentation, providing content templates and pre-written skins, Forrest is unequalled at enabling content producers to get their message out fast. This separation of concerns makes Forrest excellent to publish project documentation (notably software projects), intranets, and home pages, and anything else you can think of.

Forrest is far from a quick and dirty solution however. Forrest is built on the worlds leading XML application framework, Apache Cocoon, which provides advanced users with extremely powerful publishing capabilities.

* Multiple task-specific source XML formats can be used (How-To, FAQ, changelogs and todo lists supported natively). Source formats include: Apache xdocs xml format, plain html documents, some Wiki formats, a subset of DocBook, ...
* Multiple output formats supported, for example HTML and PDF (using Apache FOP).
* SVG to PNG rendering (using Apache Batik). Simply drop the SVG in the appropriate directory and it will be rendered as PNG.
* Transparent inclusion and aggregation of external content, like RSS feeds.
* Anything else possible with the Cocoon sitemap. Using database queries, charting, web services integration; the possibilities are constantly growing as Cocoon grows. See the Cocoon Features list for the full suite of capabilities.
* Based on Java and XML standards, Forrest is platform-independent, making for a documentation system that is just as portable as the XML data that it processes.

Unique amongst comparable documentation tools, Forrest generates sites that can run both interactively as a dynamic web application, or as statically rendered pages.

This provides a path for site growth: start off small and static, and if dynamic features (user login, forms processing, runtime data, site search etc) are one day needed, these can be accommodated by switching to webapp mode.

Running as a webapp has a major advantage during development: content can be written, and then the rendered output viewed almost instantly in a web browser. This webapp technique enables Forrests edit/review cycle to be faster than command-line transformation tools.

Skaringa is an API for Java and XML language binding.
It transforms Java objects into XML documents and back, and can generate XML schema definitions for a Java class.
Typical applications are data exchange, object persistence, object transformation, and driving XML based presentation layers.
Skaringa is designed for speed and simplicity, supporting a wide range of types. Skaringa works with all Plain Old Java Objects (POJOs), it is not limited to special cases, like JavaBeans.
Enhancements:
- New layout of documentation and website.
- Use SiteBuilder to generate HTML documententation.

Compendium is a tool to generate encyclopedia-type Web sites (e.g., databases of books, authors, publishers, and literary genres) from content housed in a MySQL database, based on HTML templates.

It generates pages with relatively static content and relies on Ruby on Rails for providing a backend to maintain the database. Compendium project radically separates content (in the database) from presentation.

To facilitate this separation, it allows users to define their own custom tags and provides a simple translation engine to deal with, for example, tables of contents and navigation paths.

Quad-Pres stands for Quick and Dirty Presentation and is a Perl and Web Meta Language based tool for generating HTML presentations.
Quad-Pres is standards compliant (XHTML 1.0), and generates a real URL tree.
Main features:
- Uses Web Meta Language.
- Organizes the lecture into a hierarchy of sections and subections.
- Generates tables of contents, and navigation links.
- Links to a common CSS StyleSheet.
- A common HTML header and footer.
- Can be generated into a web-server directory or dynamically served using a CGI script in the presentation directory.
- Written in pure Perl and so is very portable.
- The generated code is compliant to XHTML 1.0.
- Support multiple themes that customize the look and feel of the slides.
- Supports setting several parameters to the pages: doctype strictness, language, character set, body direction.
Enhancements:
- Added the Template-Toolkit configurable configuration directives.
- Added the $translate_control_text subroutine.
- Fixed some unicode problems.
- Some other bug-fixes.
- Added an automated test suite.

SciPres is a system for creating animated presentations. SciPres was inspired by Slithy, a python-based system developed by Douglas Zonker.

In short, SciPres is to PowerPoint what LaTeX is to Microsoft Word: you script your presentation using a text editor, rather than using a WYSIWYG system.
