Temporary storage for Meandre’s distributed flow execution
Designing the distributed execution of a generic Meandre flow involves several moving pieces. One of those is the temporary storage required by the computing nodes (think of it as one node as one isolated component of a flow) to keep up with the data generated by a component, and also be able to replicate such [...]
Liquid: RDF endpoint for FluidDB
A while ago I wrote some thoughts about how to map RDF to and from FluidDB. There I explored how you could map RDF onto FluidDB, and how to get it back. That got me thinking about how to get a simple endpoint you could query for RDF. Imagine that you could pull FluidDB data [...]
From Galapagos to Twitter: Darwin, Natural Selection, and Web 2.0
Yesterday I was visiting Monmouth College to participate on the Darwinpalooza which commemorates the 200th anniversary of Charles Darwin’s birth and the 150th anniversary of the publication of On the Origin of Species. After scratching my head about about what to present, I came out with quite a mix. You will find the abstract of [...]
Liquid: RDF meandering in FluidDB
Meandre (NCSA pushed data-intensive computing infrastructure) relies on RDF to describe components, flows, locations and repositories. RDF has become the central piece that makes possible Meandre’s flexibility and reusability. However, one piece still remains largely sketchy and still has no clear optimal solution: How can we facilitate to anybody sharing, publishing and annotating flows, components, [...]
