oSIP implements the Session Initiation Protocol (published by IETF as RFC 3261). It can provide signalling capabilities for multimedia applications (IP phones, etc.). It provides a fully usable parser for the SIP syntax and implements the "transaction layer" as defined in the draft. It also provides an SDP parser and extra features for the User Agent. It can be used to build both proxy and IP phones.
php_lib_login is a library for PHP, designed to allow Web site developers to add login and password protection functionality quickly and easily. Basic login functionality including email-based, question-protected password reminding, user-creation of accounts, password changing, ip banning, and selected page protection can be implemented with about 15 lines of code. php_lib_login is designed to work with numerous different databses, including MySQL, postgreSQL, MSSQL, ODBC, Access, and more through the use of the adodb library, and supports several different human languages as well.
Check is a unit test framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.
LsmLib is a C library for archiving directories and files into XML. It is useful if your document must embed the content of external files (e.g. pictures). It can also dump the signatures of a directory without the content of the files, for administration purposes. LsmLib is distributed with lsm2, a command line front-end.
Quick Template is a template library intended for use in CGI scripts. The library will be released in 6 versions: Plain Perl, Plain PHP, C version, PHP/C module, Perl/XS version, and C++ version. All of them will support uniform syntax (fully compatible with Xtemplate). The Perl version is the only one that has been released at this stage.
Raptor is a C library providing a set of parsers and serializers for Resource Description Framework (RDF) triples by parsing syntaxes into RDF triples and serializing triples into a syntax. The parsers support RDF/XML, N-Triples, GRDDL, and Turtle, and via RSS tag soup: XML RSS, Atom 0.3, and Atom 1.0. The serializers support RDF/XML (3 flavours), Turtle, DOT, N-Triples, RSS 1.0, and Atom 1.0. Raptor handles RDF/XML as used by RDF applications such as RSS 1.0, FOAF, DOAP, Dublin Core, and OWL. It can use either expat or libxml2 for XML parsing, libcurl when available for URI retrieval, and is portable to many POSIX systems.
XPLC is a component system that tries to enable the use of components in a pervasive way. It aims to be easy to use, have low speed and size overhead, and be language and platform neutral. Basically, the idea is to leave no excuse for an application not to be component-enabled (being a component and/or using components).
