The need to extract the metadata from all the institutional repositories resulted in the creation of the Open Archives Initiative Protocol for Metadata Harvesting (
OAI-PMH), which remains in use today.
At the same time, mirror services and other archives based on
OAI-PMH could collect works and metadata deposited in institutional repository (i.e.
The CKAN data portal and repositories in each domain can mutually harvest and share information based on the
OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting).
Although GeoNetwork can handle Dublin Core records, we found that harvesting them with the
OAI-PMH protocol stripped out several desired elements, and we were faced with a great deal of work to customize it for extended Dublin Core.
Even something as simple as identifying whether an entry harvested via
OAI-PMH has full text attached becomes a nightmare.
En este trabajo, se presenta un marco de trabajo para la publicacion de los datos bibliograficos extraidos de repositorios digitales que usan
OAI-PMH, siguiendo los principios de Linked Data y el ciclo de vida para la publicacion de datos enlazados.
Dowling stressed that
OAI-PMH is handling the bulk of the work when it comes to university participation.
