Resumo
Digital Archives are complex structures composed of human resources, state of the art
technologies, policies and data. Due to the heritage keeping role that archives assume
in our society, it is important to make sure that, the data that is produced by our
organizations is preserved accordingly in order do document is activity and provide
evidence of their activities.
Information stored in an archive must be treated differently than other types of information
because it is kept with the purpose of providing evidence of some organizations activity.
Due to this fact some properties should be preserved for long periods of time: integrity,
liability and authenticity. The preservation of this information extremely complex as digital
objects are far from being stable. They are software and hardware dependent. Normally,
their auto-preservation period is about 5 years.
In this context digital preservation practices become very important and should be part
of the institution's planning. The problem is how to keep digital objects in such a way that
their information is accessible long past their auto-preservation period.
RODA (Repository of Authentic Digital Objects) is a joint venture between public
administration and academic researchers that aims to become the public administration
repository. A repository where users can rely on digital objects authenticity and where
digital objects are expected to endure long beyond the 5 years expectation.
For the first prototype three kinds of digital objects were considered: text documents, still
images and relational databases. We will focus this paper on the relational databases
component.
Relational databases ingestion is accomplished by migrating the original database to an
XML representation. This representation (DBML - database markup language) was
defined according to a series of requisites, trying to preserve database content, database
structure and database attributes.
Throughout the paper we will discuss the creation of DBML and report its application to
some real case studies.
