Hi, I have just subscribed to the Apache AGE project, and was going through this thread, so thought to chime in with my two cents.
As you know PostgreSQL is released under an OSI approved 'The PostgreSQL License' [1], that is very liberal in nature and allows use, copy, modify, and distribution of the code and its documentation for any purpose. It even allows the proprietary commercialization and that is the reason we have lots of proprietary variants of PostgreSQL like EnterpriseDB's Advance Server and FUJITSU's Enterprise Postgres. Similarly, we also have open source variants like AgensGraph (the one we are discussing here) and Greenplum database. The reason I am mentioning all these forks of PostgreSQL is that, all of these forks use and modifies the PostgreSQL code and doing that is totally fine, as long as the copies keep the PostgreSQL's copyright notice. [2] For instance, have a look at Greenplum database, that is a PostgreSQL variant and released under the Apache2 license. The source header in Greenplum preserves the original PostgreSQL's copyright notices and adds additional copyright messages (Greenplum's and VMWare's) on top of that [3]. Similarly, Pgpool-II code is another example that copies lots of code from PostgreSQL and uses the same portion copyright notice in the header without removing the PostgreSQL's notice [4]. So, IMHO Apache AGE could follow the same approach, keep the PostgreSQL copyright messages intact in all file headers that it copy/use from the PostgreSQL and just append Bitnine's copyright message to the header along with the PostgreSQL's message. And there is no need for PostgreSQL source files to be donated to the project as the PostgreSQL license already gives the permission to use/modify/distribute its code. 1. https://opensource.org/licenses/postgresql 2. https://www.postgresql.org/about/licence/ 3. https://github.com/greenplum-db/gpdb/blob/master/src/backend/parser/gram.y 4. https://github.com/pgpool/pgpool2/blob/master/src/parser/gram.y Thanks Best regards Muhammad Usama On Thu, Oct 28, 2021 at 4:31 AM Eya Badal <e...@apache.org> wrote: > Hello Justin, > > I fixed the link refrence issue for the latest Apache AGE(incubating) > release.
