dArceo: Long term preservation
dArceo is a system for long-term preservation of source data (e.g. master files), primarily focused on textual, graphical and audiovisual content. It makes migration of source data possible with respect to the OAIS model. Additionally, dArceo provides conversion and source data delivery functions, which may help both to build digital libraries and access source data by advanced users, e.g. humanists. dArceo can be configured to store data in the PLATON-U4 archiving services which has been developed ijn scope of the PLATON project and deployed in the Polish nationwide network PIONIER.
