Our organization uses a lot of Spotfire but there are other BI Tools in use, particularly Power BI. Our Spotfire teams of late have been getting asked to connect to what are referred to as "XMLA Endpoints". Power BI workspaces use an "XMLA endpoint" to support open-platform connectivity from both Microsoft and potentially third-party tools. Tableau can connect to these XMLA Endpoints, for example.
Ideally Spotfire would have connector that provides this capability. In the absence of such a connector, it seems likely that teams will turn to other BI Tools to meet their requirements.
