| < < | IVOA Query LanguageIf you are interested in participating in the definition of the VO Query Language, you are invited to enroll in the Virtual Observatory Query Language Working Group (voql@ivoa.net). We have a 3 layer model for VOQL as represented below. 
ADQL-0.91Based on the Pune (2004) agreement,In the Boston 2004 meeting, the working document toward a Proposed Recommendation was published. There have been a few minor changes since Pune. This version is to be discussed at Kyoto The January demos ran on ADLQ0.7.4. But we should be moving to this new version now. dev.openskyquery.net is runnind ADQL0.9 The document was created based on the Boston 2004 agreement, however, several new features, such as CREATE,INSERT,UPDATE,DELETE, have not yet been included because these will actually create a huge increase in the size of the grammar. The process of generating the ADQL schema are described in ADQL Schema generation steps. An example XSL style sheet for converting ADQL/x to ADQL/s (strings) has been provided by NCSA adql2sql-ns.xsl. An XSLT stylesheet for converting ADQL v1.0 to SQL (provided by ESAC) can be downloaded here : adql2sql_v10.xsl.This file should work just fine for v0.9 and v0.8, just by changing the namespace declaration. The XMatch and the Circle Region were not implemented as those are specific to the datamodel. The currect translation services are for 0.7.4 and are at http://openskyquery.net/adqltranslator A java client for the translation service has been prepared. SkyNodeSkyNodes and the SkyNode portal would form layer 2 and 1 of this system. At the Strasbourg meeting the skynode spec was split in two. Since release of the Standard Interfaces this has also been reomved from skynode. Finally the portal section has also been reomved leaving a leaner Skynode document. Latest SkyNode WSDL from IVOA SkyNode0_9.wsdl There are currently Java and .NET implementations of this. Nodes are registered in the Registry and may be intereacted with through the OpenSkyQuery Portal. You may get the .NET version off the help pages of openskyquery. The Basic Java version is included in the SumerSchool software from the nvo. A More Complete Java implelemtation is underconstruction by Tom McGlynn and is in the NVO CVS under contrib/tam/skynode Other groups (JVO, ESA, IndiaVO) are also looking at the java implementation.SkyNode Registry Schema ExtentionThe SkyNode also requires a registry entry you may register in the NVO registry. The schema for the SkyNode registry entry is here - OpenSkyNode-v0.1.xsd Comments should be posted on the VOQL mailing list as specified below.VOQL Sessions in Kyoto 2005 MayWG Roadmap
