In case you all haven't seen - they are conducting a similar survey to ours. There's isn't as structured but it will still be interesting to see the results.

> Subject: Architectures and data storage of LTP systems
> Dear Sir or Madam,
> As a part of our work on the development of a national data storage
> infrastructure in the Czech Republic, we are working on an extensive
> worldwide comparison of commonly used architectures of data storage and
> corresponding technical background of the Long Term Preservation (LTP)
> systems. This study is held under the auspices of CESNET, Center Cerit-
> SC,
> Institute of Computer Science at Masaryk University, and the Moravian
> Library in Brno.
> We would appreciate if you will kindly forward this e-mail to the staff
> in
> your institution responsible for the technical foundations/basis of
> your
> long term data preservation systems.
> Please, could you be so kind as to answer as many as possible of the
> following questions? The results of this "dialog survey" will be a part
> of
> a report that will be publicly available around end of this year. We
> will
> be pleased to send you an electronic or printed copy when the report is
> finished.
> The information we would like to gather includes but is not limited to:
> 1. What kind of systems do you use to ensure long-term data
> preservation?
> 2. Does your institution use any LTP system (Rosetta, Tessella,
> Archivematica)? If not, are you planning to deploy some form of LTP
> system
> in the future?
> 3. If yes, what technical solutions stays behind it (home developed,
> iRODS,
> etc.)?
> 4. Do you use your LTP system directly for serving the user copies to
> the
> public or is there any system for accessing the user copies in the
> middle
> and your LTP stores only master copies? If the later option corresponds
> to
> your situation, how often do you synchronize the content of your LTP
> with
> the system for exposing the digital objects to the public? Is the
> performance (throughput/access time) of the LTP system a key quality in
> your infrastructure?
> 5. Do you have your LTP system certified as a trusted repository
> (TRAC, NESTOR) or do you plan a certification?
> 6. What kinds of HW technologies do you use for storing the master
> copies
> (disks, tapes, hybrid solutions, etc.)?
> 7. Would you prefer one geographic location where the actual data is
> stored
> or some kind of more geographically distributed approach keeping in
> mind
> risks of physically destroying the site, e.g., by a natural disaster?
> 8. What are the main pros and cons of your LTP infrastructure (rather
> HW
> infrastructure questions than functional requirements of the LTP
> system)?
> 9. Is your LTP system OAIS (ISO 14721:2003) compliant? How much is this
> important for your institution? How would you categorize this feature
> ("nice to have", "should have", "must have")?
> 10. Do you have a document that maps your system to OAIS? Do you have
> any
> services/processes beyond OAIS? Do you miss some important
> functions/processes of OAIS and why?
> 11. Had you done a similar study before you decided to use the LTP
> system?
> If so, would it be possible to get its results?
> 12. Do you have any documents describing your solution at the technical
> and/or architectural level?
> 13. What is the approximate number of objects already stored? And what
> are
> the expected final (maximum) numbers?
> 14. And how are the objects (data and metadata) structured? In other
> words,
> how is a periodical/monograph/map represented in the LTP? How does your
> for various data types look like? What type of identifiers is used?
> 15. What extent of in-house customization was needed? Was the system
> delivered as an "out of box" vendor solution, did a contract include
> local
> customization or were you the major architects and developers?
> 16. Have you tried any form of distributed data storage? Provided you
> have
> tried some distributed data storage, how consistently is the
> application
> layer of the LTP system separated from the lower distributed data
> layer?
> 17. Is it legally permitted to keep your data saved outside the
> country/institution? If not, would you like to use some form of on-
> premise
> or spread-over-a-few-institution distributed repository for a long-term
> storage instead of cloud storage services like Amazon S3 or Google
> Storage?
> 18. Is there any centralized instance (registry of digitization) for
> monitoring a digitization and subsequent or preventive deduplication of
> the
> digitized data in your country?
> 19. Does your institution participate on exchanging the metadata with
> other
> institutions through OAI-PMH or other protocols?
> The results of our survey will be summarised in a publicly available
> report.
> Many thanks for your valuable time and please feel free to answer this
