4Suite is a Python-based toolkit for XML and RDF application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, RDF, XSLT, XInclude, XPointer, XLink, XPath, XUpdate, RELAX NG, and XML/SGML Catalogs. Layered upon this is an XML and RDF data repository and server, which supports multiple methods of data access, query, indexing, transformation, rich linking, and rule processing, and provides the data infrastructure of a full database system, including transactions, concurrency, access control, and management tools. It also supports HTTP, RPC, SOAP, and FTP, plus APIs in Python and XSLT.
auth_ldap is an LDAP authentication module for the Apache Web server. Auth_ldap has excellent performance, due to its use of aggressive client-side caching algorithms. It also has support for LDAP over SS or TLSL. It also features a mode that lets Microsoft Frontpage clients manage their Web permissions while still using LDAP for authentication.
AxKit is a mod_perl-based XML Application Server for Apache. Employing a rich set of standards-compliant techniques as well as extensible scripting options, AxKit provides on-the-fly conversion from XML to a variety of other formats including HTML, WAP, and plain text. AxKit's notable technical features include the introduction of XPathScript, a powerful, Perl-based transformation language, built-in support for XSLT, "smart" caching, and the easy creation of dynamic XML documents.
Xindice is an open source Native XML Database. It stores and indexes compressed XML documents in order to provide that data to a client application with very little server-side processing overhead. It also provides functionality that is unique to XML data, which can't easily be reproduced by relational databases.
The GlobeCom Jukebox is a music jukebox with integrated CDDB-aware ripping and groupware functionality. It is completely configurable from the Web interface, seamlessly integrates ripping from CD to encoded MP3, and supports grouping of songs, peak adjustment, account management for access, streaming of jukebox or single song, themability, album handling, and online help.
Melati is a tool for building Java-programmed websites backed by a database. It provides a generic database admin system, an object layer where the database is seen as a collection of Java objects, and transparent caching of commonly used records, selections and "computed objects", via a transparent persistence layer on top of JDBC. Melati also provides low level, fine-grained access control through capabilities, and a rapid templating mechanism, using "templets" (sub-templates) for rendering interface elements (e.g. HTML input boxes, dropdowns). Melati is closely integrated with the popular WebMacro templating engine.
