Subject: Re: vOTE CALL: RE: Counter Proposal Paper Draft 0.9
My Vote: NO Rationale ----------- IMHO, The proposal does not show how the requirements identified in: http://lists.ebxml.org/archives/ebxml-regrep/200101/msg00098.html are being addressed. Nor does it state reasons why those requirements are wrong. I had considerable difficulty understanding the proposed approach. It seems very vague. It also seems to be essentially the same as focused queries if I am not mistaken. I find that the definitions of ad hoc query and constrained ad hoc query that I had made in link cited above are clearer. I believe this paper is incorrectly calling the proposed approach ad hoc. It is not even constrained ad hoc IMHO according to my understanding of the definition. I am very dubious about the following statement in the proposal that suggests adding to our specs language that encourages variations in implementations. >>"To further support this, the ad hoc query API prescribes three categories of methods, >>required, preferred, and specific." The above will be an inpleroperability nightmare. >>"While at the same time offering a more open value model typical of ad hoc querying, where the exact query >>content is provided by a XML structure (similar to that provided by the API of UDDI methods)." UDDI provides a fixed set of focused queries. As I said before this approach suffers from a combinatorial explosion and maintenance nightmare problem. I would not hold UDDI as our guiding light or beacon. They have set a different set of requirements as their target. >>"The overall problem appears to be somewhat intractable, since an open ad hoc query language is a holy grail >>not yet invented." The above statement is not correct. Ad hoc queries have been around as long as long as I remember. They are supported in every database system I have used. Constrained ad hoc queries are even more trivial. My estimate is that an experienced programmer could implement the constrained ad hoc query approach I have advocated in about a week or two for the Registry. I respectfully submit that this is not a convincing or viable alternative. -- Regards, Farrukh "Nieman, Scott" wrote: > I am going to call a vote VIA THIS LIST. > > Very simple vote. > > SHOULD WE CONSIDER THIS DOCUMENT AT THIS TIME?
