Redland is a set of C libraries providing a high-level API for the Resource Description Framework (RDF), allowing it to be stored, parsed, serialized, queried, and manipulated. It has an object-based, modular design and comes with detailed reference documentation and examples. Redland supports all RDF vocabularies such as FOAF, RSS 1.0, Dublin Core, DOAP, and OWL, the query languages SPARQL and RDQL, and all RDF syntaxes including Turtle, RDF/XML, RDF/JSON, RSS, Atom, RDFa, and GRDDL.
Flickcurl is a C library for calling the Flickr Web service API. It handles the API signing, token management, and parameter encoding and decoding, resulting in C functions for the Web services APIs. It uses libcurl to call the REST Web service, and libxml2 to manipulate the XML responses. The library supports reading photo, tag, and comments information, the photo upload and searching APIs, and writing tags and comments. It provides utilities such as "flickcurl" to exercise the API and "flickrdf" to get RDF metadata descriptions out of photos, tags, and machine tags.
ZXID is a C library that implements the full SAML 2.0 stack and aims to implement all popular federated ID management protocols such as Liberty ID-FF 1.2, WS-Federation, WS- Trust, and ID Web Services such as Liberty ID- WSF 1.1 and 2.0. It is based on schema based code generation, resulting in an accurate implementation. SWIG is used to offer scripting language interfaces such as Perl, PHP, and Python, as well as Java. It can act as SP, IdP, WSC, and WSP.
mod_myvhost is an Apache module for dynamically configured name-based mass virtual hosting with PHP. Virtual host configurations and PHP settings are stored in a MySQL database. There is no need to have every vhost in apache's configuration file, or to restart apache after a configuration change. It is able to change PHP settings dynamically for any vhost. By default, it sets open_basedir as the vhost's rootdir, but you can change almost any parameter that exists in php.ini. For example, you can turn on safe_mode or register_globals for a particular vhost.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.
mod-vhost-ldap is an Apache 2.x module for storing and configuring virtual hosts from LDAP. It supports DocumentRoot, ScriptAlias, ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives. It's built on top of mod_ldap, so it uses its caching capabilities and can be used with a threaded Apache httpd.
The Enterprise Sign On Engine (ESOE) allows an enterprise to meet its goals for identity management, single sign on, authorization, federation, and accountability for resource access in a very extensible manner. The ESOE is built using the OASIS SAML 2.0 specification, and the ESOE's powerful authorization engine is built around a reduced version of the OASIS XACML 2.0 standard called Lightweight eXtensible Authorization Control Markup Language or "LXACML".
