Ask HN: 100 (open)data stores, 0 visualization/mining algo. exchange platforms?

I have noticed that besides the usual data publishing cases like a gov/ngo website with csv exports there are also services like http://www.infochimps.com/ http://www.junar.com/ http://knoema.com/ where some of the data is aggregated and is made easier to interact with - especially if you need to combine multiple sources which is often the case. In a similar ways we can say that a standardized format of the data itself greatly improves the accessibility and reusability.

These services often come with bundled ways of visualizing/combining the data. These seem, unlike the data, siloed in each particular service/software. I feel that there should be a standardized form/protokol (eg HTTP) through which algorithms could be made reusable in the same way as the data is.

Basically I mean something like Weka+Vis as a Service hosted by a central quality assuring entity provided together with a data marketplace based on a common algorithm form. It would serve as a marketplace for algo/mining/vis. designers, as a testbed for researchers of new approaches. Customers would just put their data in and picked what processing they want, or they could call the algos through a common HTTP API with data on their side. Onsite dedicated solution for enterprise. I realize that there are many issues with a common algorithm form because of the intrinsic variation, but maybe differen interfaces for different classes of algorithms (eg stream based, batch...) could help.

There are too many great things getting published in academia in this space that never see any real world usage (or re-use) and there is no place I know of where I could try out my ideas meaningfully.. I could implement stuff, put in some data and publish on my blog - but how is that actually useful for people who need to make sense of their data?
