English abstract

Digital repositories have experimented a significant development in recent years, from the raising of the Open Archives Initiative (OAI) to the emergence of tools as the Open Archives Initiative Protocol for Metada Harvesting (OAI-PMH). In this paper we analyze metadata from the 69 Spanish repositories available through such protocol. Also, a qualitative and quantitative analysis is performed on the data contained in those repositories. Specifically, we analyze factors that directly affect the quality of the data, identifying the most common problems. The eight most used Dublic Core fields were title, identifier, date, language, format, description, type and subject. Creator was filled only in 56% and subject is frequently missed, and also vocabulary control in general, a key aspect to offer good search results. Biggest repositories usually offer worse quality.

Los repositorios digitales han experimentado un notable desarrollo en los últimos años, en especiala partir de la formulación de la Open ArchivesInitiaitive (OAI) y de la aparición de instrumentos como el protocolo Open Archives Initiative Protocolfor Metada Harvesting (OAI-PMH). En este trabajose analizan los metadatos de los 69 repositorios españoles accesibles mediante dicho protocolo yse realiza un estudio cuantitativo y cualitativo de los datos contenidos en dichos repositorios. En especial,se analizan factores que inciden directamente en lacalidad de dichos datos, identificando los problemasmás frecuentes.
