The Xerces Java Parser is a complete implementation of the parser related portions of JAXP 1.4 and also brings Xerces into compliance with SAX 2.0.2, the DOM Level 3 Core and Load/Save W3C Recommendations, the XML Inclusions (XInclude) Version 1.0 W3C Recommendation and the XML Schema 1.0 Structures and Datatypes Second Edition W3C Recommendations. Xerces2 is the next generation of high performance, fully compliant XML parsers in the Apache Xerces family. This version of Xerces introduces the Xerces Native Interface (XNI), a complete framework for building parser components and configurations that is extremely modular and easy to program. The Apache Xerces2 parser is the reference implementation of XNI but other parser components, configurations, and parsers can be written using the Xerces Native Interface.

From the abstract: The XHTML Basic document type includes the minimal set of modules required to be an XHTML host language document type, and in addition it includes images, forms, basic tables, and object support. It is designed for Web clients that do not support the full set of XHTML features; for example, Web clients such as mobile phones, PDAs, pagers, and settop boxes. The document type is rich enough for content authoring. XHTML Basic is designed as a common base that may be extended. For example, an event module that is more generic than the traditional HTML 4 event system could be added or it could be extended by additional modules from XHTML Modularization such as the Scripting Module. The goal of XHTML Basic is to serve as a common language supported by various kinds of user agents. The document type definition is implemented using XHTML modules as defined in "Modularization of XHTML", found in ports/textproc/xhtml-modularization.

LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. The goals of the project, in the order of importance, are as follows: 1. Completeness of coverage; LibHTP must be able to parse virtually all traffic that is found in practice. 2. Permissive parsing; LibHTP must never fail to parse a stream that would be parsed by some other web server. 3. Awareness of evasion techniques; LibHTP must be able to detect and effectively deal with various evasion techniques, producing, where practical, identical or practically identical results as the web server processing the same traffic stream. 4. Performance; The performance must be adequate for the desired tasks. Completeness and security are often detremental to performance. Our idea of handling the conflicting requirements is to put the library user in control, allowing him to choose the most desired library characteristic.

mod_encoding - Apache module for non-ascii filename interoperability This module improves non-ascii filename interoperability of apache (and mod_dav). It seems many WebDAV clients send filename in its platform-local encoding. But since mod_dav expects everything, even HTTP request line, to be in UTF-8, this causes an interoperability problem. I believe this is a future issue for specification (RFC?) to standardize encoding used in HTTP request-line and HTTP header, but life would be much easier if mod_dav (and others) can handle various encodings sent by clients, TODAY. This module does just that. This module adds following directives: EncodingEngine, SetServerEncoding, AddClientEncoding, DefaultClientEncoding, and NormalizeUsername. Note by maintainer: It also solves the problem with the "hostname\\username" way of authentication that Windows machines do when they attach to a DAV server. See the use of the NormalizeUsername directive.

mod_auth_kerb is an Apache module for authenticating Web clients in a Kerberos v5 realm. Authentication may be performed via the Kerberos principal/password; it may also be done securely using SPNEGO (HTTP Negotiate auth protocol) to perform a GSSAPI/Kerberos authentication from the user's browser and Kerberos credentials directly to the server Kerberos credentials 'HTTP/host@REALM'. Because the Kerberos password is transmitted in plain text in the former mode, when using mod_auth_kerb for naive HTTP Basic (password-based) authentication, this module MUST be used in conjunction with an encryption-capable Web server (e.g. Apache) to keep that exchange private. There is no documentation provided; see the Web site for more details.

CGI::Ex provides a suite of utilities to make writing CGI scripts more enjoyable. Although they can all be used separately, the main functionality of each of the modules is best represented in the CGI::Ex::App module. CGI::Ex::App takes CGI application building to the next step. CGI::Ex::App is not quite a framework (which normally includes pre-built html) instead CGI::Ex::App is an extended application flow that dramatically reduces CGI build time in most cases. It does so using as little magic as possible. See CGI::Ex::App. The main functionality is provided by several other modules that may be used separately, or together through the CGI::Ex interface.

There are two styles of programming with CGI.pm, an object-oriented style and a function-oriented style. In the object-oriented style you create one or more CGI objects and then use object methods to create the various elements of the page. Each CGI object starts out with the list of named parameters that were passed to your CGI script by the server. You can modify the objects, save them to a file or database and recreate them. Because each object corresponds to the "state" of the CGI script, and because each object's parameter list is independent of the others, this allows you to save the state of the script and restore it later.

Catalyst::View::TT::ControllerLocal is like a normal Catalyst TT View, but with template file names relative to the current Controller. So with a set of templates like: ./root/edit.html ./root/add.html ./root/Frobniz/add.html and an action "add" in the Controller "MyApp::Controller::Frobniz", you set "$c->stash->{template}" to "add.html" in order for it to pick up the "./root/frobbiz/add.html" template. Setting the "$c->stash->{template}" from Controller "MyApp::Con- troller::Bogon" would instead pick the default template in "./root/add.html" (since there is no Bogon subdirectory under root). In addition, since there is no file "edit.html" except in the Frobniz directory, C::V::TT::ControllerLocal will default to looking for "edit.html" in ./root/ and ./root/base (or whatever you set MyApp->con- fig->{INCLUDE_PATH} to).

This module collects common URI validation routines to make input validation, and untainting easier and more readable. All functions return an untainted value if the test passes, and undef if it fails. This means that you should always check for a defined status explicitly. Don't assume the return will be true. The value to test is always the first (and often only) argument. There are a number of other URI validation modules out there as well. This one focuses on being fast, lightweight, and relatively 'real-world'. i.e. it's good if you want to check user input, and don't need to parse out the URI/URL into chunks. Right now the module focuses on HTTP URIs, since they're arguably the most common.

Protovis - A Graphical Toolkit for Data Visualization Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example. This project is led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. We welcome your contributions and suggestions.
