Issue on how to handle structured data as a XCQL and CQL term. In XCQL the type of term could be relaxed to allow any XML structure e.g. <index>geo.countryBorders</index> <relation>within</relation> <term> <gils:boundingRect xmlns:gils="urn:gils.org:termTypes"> <gils:point>13N25W</gils:point> <gils:point>25S70E</gils:point> </gils:boundingRect> </term> </searchClause> xmlns would(?) be needed to ensure no clash over typing - or just define index (e.g. geo.countryBorders) to be a particular type? How to encode in CQL? option 1: direct escaped encoding? geo.countryBorders within "<gils:boundingRect xmlns:gils="urn:gils.org:termTypes"><gils:point>13N25W</gils:point>..." option 2: different bespoke string based encoding geo.countryBorders within "boundingRect(13N25W,25S70E)" Questions: how to ensure that this is recognised as a structure not as a string? (or just define this for the particular index geo.countryBorders must be a structure of this form). How to avoid type clashing etc. Matthew
