Apache Ant

Apache Ant is a Java-based build tool.

Apache Log4J

With log4j it is possible to enable logging at runtime without modifying the application binary. The log4j package is designed so that these statements can remain in shipped code without incurring a heavy performance cost. Logging behavior can be controlled by editing a configuration file, without touching the application binary. Logging equips the developer with detailed context for application failures. On the other hand, testing provides quality assurance and confidence in the application. Logging and testing should not be confused. They are complementary. When logging is wisely used, it can prove to be an essential tool. One of the distinctive features of log4j is the notion of inheritance in loggers. Using a logger hierarchy it is possible to control which log statements are output at arbitrarily fine granularity but also great ease. This helps reduce the volume of logged output and minimize the cost of logging.

HSQLDB

HSQLDB is the leading SQL relational database engine written in Java. It has a JDBC driver and supports a rich subset of ANSI-92 SQL (BNF tree format) plus SQL 99 and 2003 enhancements. It offers a small (less than 100k in one version), fast database engine which offers both in-memory and disk-based tables. Embedded and server modes are available. Additionally, it includes tools such as a minimal web server, in-memory query and management tools (can be run as applets) and a number of demonstration examples.

KAON

KAON is an open-source ontology management infrastructure targeted for business applications. It includes a comprehensive tool suite allowing easy ontology creation and management and provides a framework for building ontology-based applications. An important focus of KAON is scalable and efficient reasoning with ontologies.

MySQL

MySQL is an attractive alternative to higher-cost, more complex database technology. Its award-winning speed, scalability and reliability make it the right choice for corporate IT departments, Web developers and packaged software vendors.

PostgreSQL

PostgreSQL is a highly-scalable, SQL compliant, open source object-relational database management system. With more than 15 years of development history, it is quickly becoming the de facto database for enterprise level open source solutions.

RDF2Go

RDF2Go abstracts the RDF triple (and quad) stores away and lets the developers focus on RDF model manipulation using familar java types: java.lang.String for Strings, java.net.URI for URIs and BlankNode for blank nodes.

RDF2GO is an abstraction over triple (and quad) stores. It allows developers to program against rdf2go interfaces and choose or change the implementation later easily.

This is a new project implementing a UDRT-based compositional semantics for Lexicalized Tree Adjoining Grammars (LTAG). It builds on the XTAG Project. It will be used in several projects relying on natural language understanding.
