DBpedia has moved to GitHub:
https://github.com/dbpedia/extraction-framework/wiki
The mailing lists are still hosted by SourceForge.
DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia and to link other datasets on the Web to Wikipedia data.
Ontology Design Patterns (ODPs) are well known and efficient modeling solutions for ontologies. This public catalog offers a collection of well documented and tested ODPs, including examples from the biological knowledge domain, implemented in OWL.

Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
The Movinator is a movie database application. It manages information about movies plus ratings assigned to movies by movie critics. Based on these ratings and user ratings, the application can also make movie recommendations.
LucidDB is a DBMS optimized for business intelligence. Besides architectural innovations such as column-store, it supports many advanced features from SQL:2003, including SQL/MED and user-defined transformations written in Java.
WQuery is a domain-specific query language designed to process WordNet-like lexical databases. It may be used as a standalone application or as an API to a lexical database in Java based systems.
MoMS (Model Management System) is a model management system for statistical models, a little bit like a database management system. Instead of having tables, we have models that can be updated and queried.

This is intended as an open-source, multi-platform link diagramming tool for intelligence analysis. The goal is to be able to store objects using any database abstraction or in XML. This project needs much wheel reinvention, so assistance is welcome.
SIRIUS Ramsetcube 2011 born on the old Ramsetcube project of 2008. It is a powerful and easy to use cube designer aimed to help create and build OLAP schemas. The models can be exported to XML and the data format can be customized for the great OLAP
Ontology MApping FRAmework Toolkit allows to create semantic relations between two (source and target) ontologies, and apply such relations in translating source ontology instances into target ontology instances.
MAPONTO is an interactive tool for discovering semantic mappings between database schemas and ontologies as well as between different database schemas. The tool analyzes semantics in the input schemas and ontologies for generating semantic mappings.
Snowflake is a CASE Tool directed towards data warehousing projects. Through an easy to use graphical interface, it allows the construction of a conceptual design of the data warehouse or data mart, using a simple multidimensional notation.
Mandarax is a pure Java implementation of a rule engine. It supports mutiples types of facts and rules based on reflection, databases, EJB etc, supporting XML standards (RuleML 0.8). It provides a J2EE compliant inference engine using backward chaining.
Wikipedia Concept Association Map (WCAM) is new approach for textual knowledge representation and understanding. All concepts and associations are stored in a graph database for better performance and easy distribution.
GridSQL is an open source shared-nothing clustered database system for data warehousing designed for PostgreSQL. GridSQL includes intelligence to parallelize over multiple servers for achieving faster query response times.
The Pentaho Personalizer is based on the "dead" project PentahoLooker. The Pentaho Personalizer is sponsored by Lizacom and have a "commercialy" financed core of developers to ensure that the project do not "die" by lack of time or interest.
