DocBookWiki can display and edit DocBook documents online. It can display several documents at once (a list of books), and each of them can be in several languages. Editing can be done in several modes (like text/wiki, HTML, XML, etc.), but the basic format is always XML/DocBook. Each document can be automatically converted into other formats for downloading. The history of modifications is kept in SVN, and any previous versions of a document can be recovered.
OpenCartable is an online tool for teachers and their students organized around textbooks and bibliographies of links to Web sites or uploaded files. The "todo" links (or resources) can be affected as works that the student answers and the teacher corrects and marks. The focus is on simplicity, with students only using three pages: their desk, textbooks, and works. Users are grouped in a school, and teachers manage their students through groups. The contents are written as standard DocBook files plus a LOM (Learning Object Metadata) schema that can be shared among OpenCartable servers using simple tools like rsync.
Annotate provides an annotation facility for DocBook documents. It enables visitors to an online version of a DocBook document to add comments to any paragraph or chapter of the document. It extends the DocBook XSL stylesheets, leading to modified HTML output which contains anchors at those places where annotations can be made. Comments and notes are stored in a DBMS. A CGI program then merges the HTML document and the comments to produce the output for the visitor.
The Java Wikipedia API (Bliki engine) is a parser library for converting Wikipedia/Mediawiki syntax to HTML. It supports wiki tags for bold, italic, headers, nowiki, source, table of contents, tables, lists, categories, footnotes (references), images, syntax highlighting of source code fragments, templates, and template parser functions.
uWiki is a minimalistic wiki engine. All actions are implemented in external scripts. These scripts are wikified, and thus the wiki is extensible by itself. All dynamic access is protected through ACLs. Wiki content and Web content can be mixed in the same directory hierarchy. Markup engines and revision control are plugin-able. Currently, asciidoc as the markup engine and git as the revision control backend are provided. Subdirectories can form independent sub-wikis with own revision control. Features like distributed pages that syncronize between wikis, spam protection, and batch jobs to schedule mirroring of other content (bittorrent, git, rsync, and wget) are in planning.
PHPTAL is a fast, safe, XML-based template engine for XHTML and HTML5. It implements Zope's Template Attribute Language, which has clean, concise syntax that is compatible with XML tools (no custom ugly tags), and template source files can even be previewed in Web browsers or opened in WYSIWYG editors. Templates are compiled to PHP and cached, giving great performance and taking advantage of PHP accelerators. PHPTAL by default ensures well-formed output and escapes XML-unsafe characters everywhere, which means that your pages can be completely safe against HTML-injection (XSS) without great effort. It features fine-grained caching of output, pre- and post- filters, internationalization via gettext or custom backend, creation of custom template attributes and expressions, and templates loaded from non-standard sources (e.g. databases). It supports UTF-8 well, is easy to integrate and redistribute with PHP frameworks and applications, and has an object-oriented design and a comprehensive unit test suite.
