greeNsort® Notification and Certification

The greeNsort^® brand name and logo is a protected trademark. In order to advertise your software with the greeNsort^® brand, we offer two programs, Self-certification and External certification.

Self-certification

greeNsort self-certification logo

You may decorate your software with the above greeNsort^® self-certification logo if all of the following conditions apply:

your to-be-certified software is completely open-source (not necessarily free)
if the to-be-certified software is not free, you have paid an annual self-certification fee of 1000$
you have replaced inferior sorting algorithms with greeNsort^® algorithm or with algorithms superior to greeNsort^®
for each sorting algorithm you use, you have sent a proper notification record to our email API (with a reason for non-greeNsort^® algorithms)
you will not give the impression of external certification greeNsort^®
you will not use greeNsort^® brand name or logos in the context of criminal or defamatory activities
by using a greeNsort^® logo you agree to a contract penalty of 1000$ (Free-OSS) and 100,000$ (non-Free-OSS) in case you violate these conditions

Notification API

**Request for comments: we plan the following API, please give feedback on this at feedback[at]greensort.org

Our algorithms are free, but please inform us if you use them in production by sending an email with the subject “just-using” or “self-certify” to notify[at]greensort.org. Please start the email with this header-row

RolloutBeginDate,RolloutUntilDate,SelfCertification,ResponsibleFirstName,ResponsibleSurName,ResponsibleEmail,InstitutionName,OldAlgorithmName,NewAlgorithmName,NewAlgorithmReason,PercentSavingRAM,PercentSavingCPU,PercentSaving,ProgrammingLanguage,ImplementationType,ImplementationName,ArtifactName,ArtifactModule,ArtifactProc,ArtifactType,ArtifactIsFree,ArtifactFOSSLicense,ArtifactURI

and then provide one or more rows with the following comma-separated fields in the body of the email:

RolloutBeginDate (YYYY.MM.DD or empty for just terminating usage or self-certification)
RolloutUntilDate (YYYY.MM.DD or empty for open-ended usage or self-certification)
SelfCertification (one of {0|1})
ResponsibleFirstName (doubly quoted “string”)
ResponsibleSurName (doubly quoted “string”)
ResponsibleEmail (doubly quoted “string”)
InstitutionName (doubly quoted “string”)
OldAlgorithmName (doubly quoted “string” or empty)
NewAlgorithmName (doubly quoted “string”)
NewAlgorithmReason (doubly quoted “string” or empty)
PercentSavingRAM (integer)
PercentSavingCPU (integer)
PercentSaving (integer or empty)
ProgrammingLanguage (doubly quoted “string”, spelling like https://en.wikipedia.org/wiki/List_of_programming_languages_by_type)
ImplementationType (one of {“owncode”|“libcall”})
ImplementationName (if libcall name of lib else empty)
ArtifactName (doubly quoted “string”)
ArtifactModule (doubly quoted “string” or empty for complete artifact)
ArtifactProc (doubly quoted “string” or empty for complete module)
ArtifactType (one of {“lib”|“app”})
ArtifactIsFree (one of {0|1})
ArtifactFOSSLicense (if FOSS doubly quoted “string” otherwise empty, please use SPDX ID from https://opensource.org/licenses/)
ArtifactURI (doubly quoted DNS resolvable path to complete open-source code, must not require any log-in)

External certification

greeNsort brand logo

Use of the greeNsort^® brand logo requires external certification. Note that for non-open-source software self-certification is not available, non-open-source software requires external certification. For an external certification please contact us at certification[at]greensort.org .

We all need people who will give us feedback. That’s how we improve. ―&Bill Gates
