TaskRunner allows the user to: build complex adql queries against remote databases; and invoke long-running remote applications.
There's experimental support for an early version of TAP
The latest version adds basic support for asynchronous TAP (Table Access Protocol) queries.
To see it in action - In VOExplorer search for the resource Hipparcos catalogue - ivo://uk.ac.cam.ast/newhipparcos-dsa-catalog/HIPPARCOS_NEWLY_REDUCED (or subscribe to this resource list) and then choose the TAP Query action. (In the final a release, we'll probably not differentiate between cea-adql and tap-adql - it's not relevant to the user). A simplified form of the task runner appears, from which queries can be built and submitted.
At the moment, selecting the output format for the result does not work - so I've omitted that from the UI. (I might omit it from the production version too). Likewise, it's not possible to instruct TAP/DSA to send results to myspace - so that's been omitted too.
