Descrição
Este módulo implementa a predefinição {{Webarchive}}.
Categorias de monitoramento
- Categoria:!Predefinição Webarchive wayback links (20 891) – links no Wayback Machine
- Categoria:!Predefinição Webarchive webcite links (75) – links no WebCite
- Categoria:!Predefinição Webarchive archiveis links (9 280) – links no Archive.is
- Categoria:!Predefinição Webarchive outros arquivos (136) – todos os outros websites que não tem a sua categoria de monitoramento
- Categoria:!Predefinições Webarchive arquivos desconhecidos (30) – a predefinição não reconhece o URL do arquivo; Isso pode indicar um erro nos dados; ou se a própria predefinição necessita de atualização para mostrar o novo site do arquivo
- Categoria:!Avisos na predefinição Webarchive (84) – erros menores que deixam a predefinição funcionar mas deixam uma mensagem de aviso em vermelho
- Categoria:!Erros na predefinição Webarchive (2) – erros que normalmente requerem intervenção humana
