ADQL Version Track ADQL v WD ADQL v PR, before Trieste ADQL v PR, after RFC period ADQL v PR, after WG Chairs review ADQL v REC, approved by Exec IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v WD Released right before RFC period started. Collected VOQL-TEG inputs/agreements after first complete review. More details here: Changes: - BNF updated with all geometrical constructs. - Link to RFC 2119 added in the 'References' section. - Editorial typos corrected. - SELECT compact syntax in line with BNF. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR Released before last PR version for RFC period. Change: - Version number changed to 2.0 as indicated by IVOA Document Coordinator. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (1/5) Released after Implements RFC comments and agreements Reviewed by WG/IG Chairs and Exec after RFC period. More details here: IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (2/5) RFC/Edit changes Typos and other editorial issues corrected. Sub-sectioning improved to reduce the section levels. Links to STC and STC-S added in the 'References' section. BNF update in line with rest of changes. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (3/5) RFC/Units changes Trigonometrical functions definition improved As adopted from SQL, use radians. Legal return and input values made explicit. Geometry constructs use degrees. If Cartesian coordinates, no units. Vector must be normalized. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (4/5) RFC/Coord changes COORDSYS function to extract coordinate system from geometry. Legal ranges for spherical coordinates set to [0,360] and [-90,90]. Coordinate system string literals to be STC compatible. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (5/5) RFC/Geom changes BOX defined as of STC replacing RECTANGLE. Samples of usage provided. Improved description and samples for: AREA, CENTROID, CIRCLE, CONTAIN, INTERSECTS, POINT, POLYGON and REGION LATITUDE and LONGITUDE functions replaced by COORD1, COORD2. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (1/2) Released during Addresses first round of comments by WG/IG Chairs after RFC period was closed. More details here: IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz

ADQL v PR (2/2) Changes: - Clarify relationship between geometric data types functions to the STC - Explicit ref. to STC-X v1.33 and STC-S v Replace wrong STC-like coordsys samples. - Page numbers added. - Correct POWER function's arguments description - Update ATAN2 function's description. - BNF update.

ADQL v REC Released on 30 October 2008 as IVOA Recommendation. IVOA Interoperability Meeting Oct 2008, Baltimore IVOA VOQL-TEG – Iñaki Ortiz
