| Abstract: |
The Special Astrophysical Observatory of the Russian Academy of Sciences
(SAO RAS) has an archival system which contains heterogeneous digital
collections with observations, obtained on the different instruments of
the observatory since 1994. For a sufficiently long period of existence
of the archive there have been significant changes in data formats, data processing methods and storage of information.
To date, the archive capacity is 1.5 TB.
By modern standards, it is a small archive, but most of the
observatories in the world produce archives of a similar volume and content.
The most pressing data management tasks in any archive include
validation of data, ingestion, access, long-term preservation with
support for timely migrations to new data media. Standardization of these
stages, the creation of software on the base of the standards for the
entire community, can be a good help for such archive providers, whose
capabilities in terms of software development are often limited because
of the small size of a team and the necessary level of
training. |
