Precepts
1993 Licensing Fiasco
- Gopher-Software-Licensing-Policy ANCIENT .txt = (this policy hung a dark cloud over GopherCon 93)
- Gopher-Software-Licensing-Policy NEW .txt = (the lifting of prohibition had little impact, occuring seven years too late)
- - GNU General Public License .txt
- Peers Condemning the Ancient Gopher License
- UMN Justifying their Ancient Gopher License
- Desertion Warnings over the Ancient Gopher License
Note: Extreme industry backlash towards what were perceived as immorally greedy Gopher protocol license owners, motivated CERN out of fear to quickly renounce its own restrictive
Official Standards Referencing Gopher
- Port Numbers .txt - IANA Reserved Port Numbers = (be aware that the service listed beside the Port number is the Primary user. Servers may use any Port as a secondary user, as long as they don't conflict with a primary user. Clients should therefore allow access through any Port. In the '90s, when it was common for servers to be running on individual machines with separate IP addresses, several legacy Gopher Clients and
multi-protocol HTTP Browsers were written which improperly hard-coded Gopher server access exclusively through Port 70.)
- Character Encoding - For compatibility reasons, Gopher selector strings must always be constructed using the 7-bit "US-ASCII" character encoding scheme. 8-bit character encoding can be substituted for text intended to be displayed by a Client (although some older mainframe and TeleType terminals will be unable to display any high characters), but the "Latin-1" (ISO-8859-1) character set should be used in preference to the "UTF-8" character set whenever possible.

*Note: RFC1436 was released as an informational memo. This prologue, describing how Gopher was deployed internally at one university and speculating how it -might- possibly be used on the Internet, firmly states that it "does not specify an Internet standard".
Enhancement Suggestions for Gopher
Today Gopher is often dismissed as inept, because people are comparing the greatly expanded HTTP protocol (delivering pages containing extensive lines of code and executed with numerous browser plug-ins) to the still lean Gopher protocol. This however is an unfair "apples to oranges" rendering comparison of enhanced against stagnant (Gopher is not inherently restricted to remaining unenhanced). One needs only to look back at how HTTP websites and Browsers appeared in the early '90s, to realize that if it was not for the Gopher licensing fiasco, Gopher would still be a major component of the Web; with HTTP serving up commercial advertising and shopping, and Gopher serving up organized resources and blogs.
(Both Gopher and HTTP are Web technologies, which can even be merged seamlessly using
Initially fully graphical browsers were not available, and Gopher, before its licensing induced stagnation, was actually on the fast-track to popularizing them first. In fact, advancing even beyond static graphical browsing is relatively easy with Gopher (due to the universal understructure the Protocol imposes on every Gopher Server), and graphical
