While some people are wondering whether ‘XMLA is dead’ and call to ‘Resurrect the XMLA Council’, the reality in the field is quite different. There are, of course, plenty of XMLA clients, and new ones being born – the server side, XMLA providers also gain numbers. Today open-source OLAP server Palo announced support for XMLA and MDX.
Actually, they announced even more – also support for OLEDB for OLAP (which is where XMLA came from). Of course, the biggest driver seems to be compatibility with Excel PivotTables, but whatever is driving it, it should be pretty clear to everyone, that XMLA is not dead, it is alive and well, even though there were no changes in the standard since 2003 – maybe it means we did such a good job on the standard, that XMLA 1.1 is enough for everything :)
