Introduction to SFgate

SFgate is a gateway between the World Wide Web (WWW) and WAIS (Wide Area Information Servers) written in Perl. It is specially suited for usage with freeWAIS-sf, as it supports all its extensions. But all servers speaking the WAIS protocol can be contacted. SFgate is designed as a CGI script so that it is usable with any WWW server supporting the CGI standard.

• freeWAIS-sf fields as input fields in HTML forms
• parallel querying of any number of WAIS servers
• local search: high efficiency for WAIS databases residing on the same host as the WWW server; these databases are queried directly without contacting a WAIS server
• conversion of result documents, e.g. conversion of literature references into BibTeX
• multiple language support: SFgate can do its output in English, Dutch, French, German, Italian, Portuguese and Spanish
• several options to influence the appearance of query results
• handling for heterogeneous databases
• real parallel processing of search requests on different WAIS databases
• the converting documents mechanism changed, to provide own converters SFgate's code needs not to be changed any longer

The current patch level of SFgate 5.1 is 11.

Year 2000 compliance

SFgate is year 2000 compliant. There is simply no point where the date comes into play. The only point where confusion could arise is in the case you use date fields: if you specify in a query a year in YY format, it is interpreted as 19YY.
