| Abstract: |
The New Archiving Distributed InfrastructuRe (NADIR) is under
development at the Italian center for Astronomical Archives (IA2) to
increase the performances of the current archival software tools at the
data center. Traditional softwares usually offer simple and robust
solutions to perform data archive and distribution but are awkward to
adapt and reuse in projects that have different purposes. Data evolution
in terms of data model, format, publication policy, version, and
meta-data content are the main threats to re-usage. NADIR, using stable
and mature framework features, answers those very challenging
issues. Its main characteristics are a configuration database, a multi
threading and multi language environment (C++, Java, Python), special
features to guarantee high scalability, modularity, robustness, error
tracking, and tools to monitor with confidence the status of each
project at each archiving site. In this contribution, the development of
the core components is presented, commenting also on some performance
and innovative features (multi-cast and publisher-subscriber
paradigms). NADIR is planned to be developed as simply as possible with
default configurations for every project, first of all for LBT and other
IA2 projects. |
