Slug Trails

The Linksys NSLU2 (aka Slug) is an excellent platform for a remote data logging and forwarding. These are the steps I took to set things up to get data from a weather station onto our sailing club website.

Plone Ontologies

Plone as a SPARQL endpoint will need, at least conceptually, some ontologies. To be a truly dynamic set of components, we should be able to build our ontologies programmatically based on the underlying schemas. Here's a stab at describing the mapping between Plone's portal_catalog and OWL.

ODDS

Ontology Driven Distributed SPARQL

Plone and SPARQL

One side to the Plone/SPARQL coin is to let Plone expose its catalog as a SPARQL endpoint. The other side lets Plone/Zope access remote SPARQL endpoints and deal with result sets.

Project Name

A project needs a name.

Core Components

We will use the term "components" rather than "services", to enforce the idea that the system parts are re-usable and exchangeable.
