The Vortex refInfo API, added in Texis version 8, provides a set of functions for getting details of HTML references (links). The API is implemented as a set of SQL functions which return and manipulate in-memory objects, for maximum code flexibility - the API is used almost exclusively in Vortex, not SQL. These objects are obtained from a call to <urlinfo allrefs refInfo> (here) or the like, after a fetch.
