Free publishing software software for linux

Atom Publishing Protocol framework for Rubys goal is to make adopting Atom Publishing Protocol(APP) support in web applications as easy as it can be. This is to be reached by implementing a framework that handles the protocol-level duties for the programmer, while not making any requirements for the site design. Details of the project are laid down in a roadmap.

The way that this framework realizes this functionality is by implementing a base class for each back-end. At the moment there is only one back-end, for Ruby on Rails. The base classes then expect that the users application responds to a certain interface that makes the content information storing the responsibility of the application.

While implementing the framework Im going to follow two principles, simplicity and generality. Simplicity in that sense that the framework only does what it needs to do, nothing else, thus staying out of the way of the developer, laying down as few constraints on the application as possible.

Generality principle follows on the same track. As the overhead from using the framework is in the minimum, the field of application gets wider. From technical point of view the generality will be helped by multiple back-ends that enable the use of framework in many different environments.

The APP is currently an Internet-Draft and hence most likely will change in near future. For this, it is better to keep the framework as simple as possible so that it can be refactored with minimum effort.

The work for this project is freely available(MIT licensed) from this website. I am writing this framework as a part of my final thesis at the Tampere University of Technology, Finland.

DocBook to LaTeX/ConTeXt Publishing project is splitted in two instances working on the same principles. Both instances are intended to produce DVI, PostScript, PDF documents from DocBook SGML or XML sources, by converting first to a high level set of TeX macros.

Even if close, each instance is provided as an independent package and works alone. The available instances are:

dblatex

Publishing is done by using LaTeX.

dbcontext

Publishing is done by using ConTeXt.

- A user-friendly GTK+-based interface
- Layout templates
- An XML-based typesetting engine called xml2ps
- User-defined text formatting with XSLT stylesheets
- Unicode support
- Importing EPS (Encapsulated PostScript) files
- Importing images in JPEG, TIFF, PNG (no transparency), XPM, PNM, RAS, BMP and GIF format

Open Journal Systems (OJS) is a journal management and publishing system that has been developed by the Public Knowledge Project through its federally funded efforts to expand and improve access to research.
Main features:
- OJS is installed locally and locally controlled.
- Editors configure requirements, sections, review process, etc.
- Online submission and management of all content.
- Subscription module with delayed open access options.
- Comprehensive indexing of content part of global system.
- Reading Tools for content, based on field and editors choice.
- Email notification and commenting ability for readers.
- Complete context-sensitive online Help support.
OJS assists with every stage of the refereed publishing process, from submissions through to online publication and indexing. Through its management systems, its finely grained indexing of research, and the context it provides for research, OJS seeks to improve both the scholarly and public quality of referred research.
OJS is open source software made freely available to journals worldwide for the purpose of making open access publishing a viable option for more journals, as open access can increase a journals readership as well as its contribution to the public good on a global scale (see PKP Publications).

Absolut Engine is a news publishing system. It features three-layer access (admin/chief/editor), article posting, editing, and deleting. Absolut Engine includes a powerful image managing tool, a file manager, and a related articles manager.
