OJSBR
Open-source plugins for PKP software — Open Journal Systems (OJS) and Open Monograph Press (OMP) — maintained by the Brazilian community at ojsbr.com.
🇧🇷 Plugins de código aberto para os softwares da PKP (OJS e OMP), mantidos pela OJSBR. Tudo aqui é distribuído sob a GNU GPL v3, para toda a comunidade usar e contribuir.
Each plugin lives in its own repository, with one branch per supported PKP version (stable-3_5_0, stable-3_4_0, …). Installable .tar.gz packages are available on each repo's Releases page and in the Packages tab (GitHub Container Registry).
When a plugin exists for both applications, the OMP edition lives in its own repository with an Omp suffix (staticEditorialTeam → staticEditorialTeamOmp). The plugin folder inside the package keeps the original name — PKP derives the class namespace from the installation directory, so never rename it.
🇧🇷 Quando o plugin existe para as duas aplicações, a versão de OMP tem repositório próprio com o sufixo Omp. A pasta do plugin dentro do pacote mantém o nome original — o PKP deriva o namespace da classe do diretório de instalação, então não renomeie a pasta.
The same package installs on either application.
🇧🇷 O mesmo pacote serve para as duas aplicações.
