What is ADQL ?

ADQL is a SQL-like language which includes astronomical facilities to query a database. This language has been defined by the IVOA in the Recommendation of 30 Oct 2008 (Version 2.0) and is mainly used in the Table Access Protocol (TAP).

Why this library ?

In order to help Java developpers to parse, manipulate and translate ADQL queries quickly and with as few lines of code as possible.

  • Parse: read ADQL queries in text and transform them into a Java object (actually, a syntactic tree).
  • Manipulate: the generated object can be manipulated so than modifying the original query.
  • Translate: an interface and some implementations lets translating SQL into other languages like SQL.
