What is OBO-Edit?
OBO-Edit is an open source, platform-independent application for viewing and editing OBO ontologies.
OBO-Edit is a graph-based tool; its emphasis on the overall graph structure of an ontology provides a friendly interface for biologists, and makes OBO-Edit excellent for the rapid generation of large ontologies focusing on relationships between relatively simple classes.
OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine.
The OntoWare Group provides organizational and legal support for a broad range of Semantic Web related software projects. Through a collaborative and meritocratic development process, OntoWare projects deliver enterprise-grade, freely available software products that attract large communities of users.
The UMBEL project is a community one with participation encouraged. We welcome criticisms, testing, debate and discourse. The current system is not yet at acceptable production quality, and some properties and vocabulary are still experimental. Please help UMBEL become better !
The SWRC (Semantic Web for Research Communities) is an ontology for modeling entities of research communities such as persons, organisations, publications (bibliographic metadata) and their relationships. It is used in numerous applications and projects including the AIFB portal, Bibster and the SemIPort project.
This document is written for readers who want a first impression of the capabilities of OWL. It provides an introduction to OWL by informally describing the features of each of the sublanguages of OWL.

when you mix different metadata you loss on quality. Yes you can merge them but then you need to square the number of dictionaries respect than languages. AArrgh
