Hi, The first beta release of the Astro Runtime family of software products is available from http://software.astrogrid.org/beta/ar There are 4 variants of the Astro Runtime available: * PLASTIC Hub - just for client-side UI tool interop. * Astro Server Runtime - for non-UI unattended operation * Astro Client Runtime - for desktop operation * Workbench - suite of applications built upon the Astro Runtime (Astroscope, Application Launcher, Workflow editor) Each variant is available as * a webstart application, to click and run * single executable jar, to download, install and run * zip of libraries, for integration with other projects. More Information: ------------------------ Astro Runtime: The Astro Runtime is a facade for any client code that wants to access Virtual Observatory services. It's facilities are exposed via a range of techniques - HTTP / XML-RPC / Java-RMI, making it easily accessible from almost all programming and scripting languages. The runtime simplifies access to IVOA standard services : Registries, Siap, SSAP, (SkyNode coming real soon now); All AstroGrid services : MySpace, Workflow, CEA; Other popular protocols: NVO Cone-search; Useful one-off services - CDS Simbad, etc It also provides GUI components - simple dialogues that can be reused by client applications to perform common tasks (myspace microbrowser, registry browser, etc). Other benefits of the runtime include single sign-on, single-configuration, and single cache service responses - making implementation of client-side applications simpler. PLASTIC : A standard for interoperation of client-side vizualization tools . http://plastic.sourceforge.net Relationship between the current AstroGrid Workbench and the Astro Runtimes: After a period of testing, the Astro Runtimes will replace the current monolithic Workbench. The Astro Runtimes repackage the functionality of the current Workbench, so that the user/developer/ integrator can select the subset of functionality they require. Download sizes range from 3Meg (for the plastic Hub) to 24Meg (for the Workbench). The Astro Runtimes are also much more configurable - service parameters can be set trivially on the commandline even disabling services altogether. While the Workbench version probably isn't ready for production use yet, the smaller variants - Hub, ASR, ACR - should be usable with no problems. YMMV. enjoy! noel --- http://wiki.astrogrid.org/bin/view/Main/NoelWinstanley Senior Java Developer, AstroGrid Project Jodrell Bank Observatory, University of Manchester |
