I have now often encountered the same difficulties that WOS SCI searches become impossible in BibDesk Version 1.3.21 (1525).
Did these difficulties occur in previous versions?
Say I have successfully searched some references, imported some and continued reading/writing for a while. All successful so far. Then I tried to resume the searching by returning to BibDesk, typing in another keyword and author. I have to wait for a long time to get merely the message: "Unable to retrieve results. You may not have permission to use this database."
This is a generic error message when anything other than a network failure occurs. Use Activity Monitor to take a sample while it's trying to connect, and that may shed some light on the problem.
Although I have the permission, I checked it out by searching not through Z39.50, but a browser.
BibDesk's WoS search uses SOAP web services, not z39.50. Checking it through a browser is meaningless, though, since you could be going through a proxy that is bypassed for the web service. Apple's SOAP stuff is very weak.
The ISI WOS services seem to be up and running and I can easily access the wanted articles (with same system configuration). I also go back to a simple search I've done before and where I know that it should be working, only to learn that there is really something defunct with the connection. But that's all very time-consuming with the lengthy time-out behavior. BTW, I tried also to change search sites, which did also not help. The Z39.50 connectivity seems to be dead.
I haven't seen this, but the current version of BibDesk has some additional code for WoS that I haven't tested personally. It's unlikely that would cause a problem, but prevents me from saying that it certainly works. The only problems I've heard of are due to proxies.
P.S.: I tried also to check whether I'm using perhaps a too remote server on the other continent where connectivity might be more at risk and was wondering in this context where BibDesk actually stores the 'bdsksearch' data of the WOS SCI factory search. At least to have a look at it and see what it's specifications are might also help to find a solution. Anyone knows where to look?
It's compiled into BibDesk, specifically in the following (nasty) generated code:
http://bibdesk.svn.sourceforge.net/viewvc/bibdesk/trunk/bibdesk/BDSKISIWebServices.m?view=markupYou can use http://ditchnet.org/soapclient for debugging. The WSDL is listed in the BDSKISIWebServices.m file I linked above.
