	Just so as to head of any other false controversy...

	That should be Pedro's job. As I wrote in my earlier (and subsequent
	emails), I will be presenting a possible model and the supporting technology 
	around it. This model is one of two which has been proposed by the DM-catalog 
	group, but doesn't appear to be at odds with the other model (e.g. the other may
	be realized with our model, and viceversa). However, as Pedro points out, no merger 
	of ideas has yet happened so who knows what the final composition will be. 
	Nevertheless, I doubt that we will be able to address most of these 'structural'
	issues in that meeting, and I would still like to inform the wider VO community of 
	the work we have been doing.
	
	So, hopefully not to be too repetitive, my  concern in modeling catalogs has been 
	that we create an adequate structure to allow the needed, sophisticated, queries 
	that the VO applications will demand. As this need overlaps with the VOQL community, 
	I would think you all would be somewhat interested in this topic :)

	Hence, I am (still) interested in presenting details of what needs to be done
	in order to create "queriable" catalogs that meet a number of VO requirements and point
	to possible technologies that I and Ed have been researching which meet this need.
	If this approach is improper (presenting this work at this point) then I am happy to 
	withdraw my talk so that things proceed more smoothly between myself and all other
	VO groups (!!). 

	Regards, (and hopefully last email on this subject by me! Please Maria and Pedro come
	to a decision on what the right approach should be and I will follow it)
