Numerous institutions and organizations need not only to preserve the
material and publications they produce, but also have as their task (although
it would be desirable it was an obligation) to publish, disseminate and make
publicly available all the results of the research and any other
scientific/academic material. The Open Archives Initiative (OAI) and the
introduction of Open Archives Initiative Protocol for Metadata Harvesting
(OAI-PMH), make this task much easier. The main objective of this work is to
make a comparative and qualitative study of the data -metadata specifically-
contained in the whole set of Argentine repositories listed in the ROAR portal,
focusing on the functional perspective of the quality of this metadata. Another
objective is to offer an overview of the status of these repositories, in an
attempt to detect common failures and errors institutions incur when storing
the metadata of the resources contained in these repositories, and thus be able
to suggest measures to be able to improve the load and further retrieval
processes. It was found that the eight most used Dublin Core fields are:
identifier, type, title, date, subject, creator, language and description. Not
all repositories fill all the fields, and the lack of normalization, or the
excessive use of fields like language, type, format and subject is somewhat
striking, and in some cases even alarmingComment: BIREDIAL-ISTEC 2017, in Spanis
