Solução 2 - Dspace

Para corrigir o seguinte erro, que ocorre na importação de dados para o Dspace:

• java.lang.IllegalArgumentException: The metadata field "xxx" requires an authority key but none was provided. Vaue="null"

Devem ser efetuados os seguintes passos:

1) Parar o Tomcat;

2) Apagar o conteúdo da pasta [dspace-base]/imports;

3) Comentar as linhas 1653 à 1678 no arquivo [dsapce-base]/config/dspace.cfg:

choices.plugin.dc.subject.cnpq = common_cnpq
choices.presentation.dc.subject.cnpq = suggest
choices.closed.dc.subject.cnpq = true
authority.controlled.dc.subject.cnpq = true
authority.required.dc.subject.cnpq = true

## same idea for dc.publisher.program
choices.plugin.dc.publisher.program = common_publisher_programs
choices.presentation.dc.publisher.program = suggest
choices.closed.dc.publisher.program = true
authority.controlled.dc.publisher.program = true
authority.required.dc.publisher.program = true

## same idea for dc.publisher.department
choices.plugin.dc.publisher.department = common_publisher_department
choices.presentation.dc.publisher.department = suggest
choices.closed.dc.publisher.department = true
authority.controlled.dc.publisher.department = true
authority.required.dc.publisher.department = true

## same idea for dc.description.sponsorship
choices.plugin.dc.description.sponsorship = common_sponsorship
choices.presentation.dc.description.sponsorship = suggest
choices.closed.dc.description.sponsorship = true
authority.controlled.dc.description.sponsorship = true
authority.required.dc.description.sponsorship = true

4) Após salve a edição do arquivo;

5) Inicie o Tomcat;

6) Refaça a importação;

7) Não esquecer de retirar o comentário as linhas, após o término da importação dos itens. Caso isso não seja feito, o auto-completar de alguns campos estará desativado.
