Check out Knoodl which facilitates community-oriented development of OWL based ontologies and RDF knowledgebases
This is mostly just a note to myself to look into Knoodl:
Knoodl facilitates community-oriented development of OWL based ontologies and RDF knowledgebases. It also serves as a semantic technology platform, offering a service based interface so that communities can build their own semantic applications using their ontologies and knowledgebases. Knoodl is a product of Revelytix, Inc. and is hosted in the Amazon EC2 cloud and is available for free.
According to their web site, Knoodl offers:
- Cloud-based application (Amazon EC2)
- Ontology editing
- Ontology import/export
- Role-based security
- Scalable RDF store (Mulgara)
- NEW SPARQL Endpoints NEW
- SPARQL query wizard (March '09)
- Ontology guided search (March '09)
- Graphical ontology mapping wizard (March '09)
- User designed widgets and gadgets for viewing data (March '09)
- User designed widgets and gadgets for entering data and submitting queries (March '09)
They tell us that:
All content in Knoodl is organized into Communities. You can browse the list of Communities by clicking on the Community menu at the top of the screen and selecting Directory. Within Communities, there are regular Wikis and there are Vocabularies. A Vocabulary is a combination of an OWL based ontology editor and a wiki. Wikitext in Knoodl is not semantic, it is there to provide users with the ability to collaborate more effectively and add rich documentation. Each Vocabulary represents an ontology. Every resource (class, property, and instance) in the ontology has its own page in the Vocabulary.
To get started, you can take the tour and see how to get started, then dive in and check out some of the example vocabularies, and see what vocabularies people have already uploaded. Better yet, register for an account, create or join a community, and start contributing!
Sounds quite interesting.
One question I have: Is the "k" in "Knoodl"enunciated or is it more like the silent "k" in "knowledge"? I am guessing that it is pronounced "noodle" rather than "ka-noodle", but who knows.
Hmmm... I wonder if any of ontologies for vocabularies include pronunciations?! Anybody have an ontology for natural language speech, the spoken word?
