Automatic classification in Ontopia

Ontopia has contained an automatic classification module under the covers for a while, but it was never documented, and there was no real interface to it, and so nobody looked at it. The module has now been properly documented for version 5.1.0, and a command-line interface has been provided.

The Ontopia web site now has a page about the classification, describing what is in the product. There is also an old presentation with some background information.

Proposal for new REST API to Ontopia

David Damen of SpaceApps has posted a proposal for a new RESTful web service interface to Ontopia. In a posting to the mailing list he says that SpaceApps is looking for community feedback on the API before they start implementing it later this summer.

At this point it is not clear whether the new API will become part of Ontopia, or whether it will be placed in the sandbox. The community feedback on the mailing list will determine the outcome.
