This is just a modest proposal ... *** How about distributing the Prolog 1000 list as a Prolog program? *** This has (at least) two major advantages: 1) One could easily show to one's supervisor just HOW NICE it is to use Prolog for querying a database...Imagine having access to all the Prolog application information with only a few keyboard strokes! 2) It would add at least one significant application to the list (B-)) I recall a very nice information retrieval system called PSI by Markus Fromherz, a stand-alone Prolog implementation for the Mac, which could be used for this...

Excuse my ignorance about this. Is PSI a genuine 'double clickable' Mac application? Or is it a Prolog program which must be loaded into a Prolog system and executed? --------------------- Mike Brady Computer Science Department, Trinity College Dublin, Ireland

Imagine asking that question about a C program. - Note that I am not saying that PSI is ideal for the Prolog 1000 database, especially because it might exclude users of other platforms. (PSI can export in many formats, though, including Prolog-readable text.) Still, using the publicity, from the ReadMe file of PSI (pronounced "psee"): PSI is a handy system for the management and retrieval of your personal data, be it addresses, CD collections, or bibliographic references. It is intended for the non-commercial user. It may not be as full-fledged as some data-base systems, but has some features that you won't find in most commercial systems. Also, you may find it easier to set up and faster to use. (Try the sample sessions!) PSI is useful for a broad range of data. Indexing with descriptors makes searching for the data you need fast, and the interface to other data-base formats (import and export) is quite powerful. PSI has been written in LPA MacProlog and is a "genuine 'double clickable' Mac application". PSI runs on all Macs with System 6 or 7 in 1MB of main memory. As LPA MacProlog isn't yet 32-bit clean, PSI isn't either. Exten- sive documentation and some examples are included. PSI is available by anonymous ftp from sumex-aim.stanford.edu, directory info-mac/app, file psi-23.hqx. It was also available on a recent Nautilus CD-ROM (if you happened to get it) and will be on the first Info-Mac CD- ROM. (End-of-commercial) Markus Fromherz <fromherz@parc.xerox.com>

That is the confidentiality issue; the database contains a lot of very useful names and addresses. We asked people to specify if they wanted information to be kept private, so the potential problem isn't there so much as with the Prolog vendors. I don't want to be party to charges of poaching customers! We've asked the Prolog Vendors' Group to adjudicate this issue and if that's cleared we'll probably make it available by ftp in several formats. >I recall a very nice information retrieval system called PSI by >Markus Fromherz, a stand-alone Prolog implementation for the Mac, which >could be used for this... but he hasn't submitted it to the Prolog 1000 yet!
