Amaya is a complete Web browsing and authoring environment, and comes equipped with a WYSIWYG style interface. It lets users both browse and author valid Web pages, with standards including (X)HTML, native MathML, and SVG documents. It also includes a collaborative annotation application (RDF).
HTML-XML-utils consists of a set of small C programs (filters) that read HTML and XML files and can add a table of contents, an alphabetical index, a bibliography, cross-references, numbered headings, remove elements, count elements, pretty-print them, etc. When it reads HTML, it assumes the code is correct HTML 4.0 or close to it.
Jigsaw is W3C's leading-edge Web server platform, providing a sample HTTP 1.1 implementation based on RFC2616 and a variety of other features on top of an advanced architecture implemented in Java. Jigsaw provides both client and server HTTP/1.1 implementations, is fast, easy to extend, flexible, and is also packaged as a ready-to-run HTTP/1.1 proxy-cache.
Net_NNTP is a PHP/PEAR library for communication with NNTP servers. Net_NNTP handles connection and protocol-level commands (RFC977), including many non-standard commands (RFC2980), via a user-friendly API which hides the actual NNTP commands/syntax. Some knowledge about NNTP and general knowledge about email and MIME is required, since parsing of content and headers is left up to the user. Net_NNTP allows advanced users direct usage of NNTP commands via the separate protocol implementation. Net_NNTP includes a fully-functional NNTP to HTML gateway demo application.
Surnia can check an OWL ontology/knowledge base for inconsistency and entailments. It is implemented as a wrapper around first-order theorem prover (OTTER, for now at least). Unlike Hoolet (which turns the OWL into FOL), Surnia just turns the OWL into triples and mixes in axioms.
GeneSyS aims to define and implement a middleware architecture for generic system monitoring and supervision. It is an Information Society Project (IST-2001-34162) sponsored by the European Commission. It provides a middleware- and agent-based approach for system monitoring and management. It uses WebServices technology (SOAP) for communication between components and XML-based descriptions of monitoring information.
LPMtool aims to be a complete package management and software distribution solution. It includes basic command line and PyGTK-based utilities for installing and removing packages, as well as tools to publish Web-based package repositories that use a GPG-based web-of-trust security model.
