2. Archiving

3. Data archiving is the process of moving data that is no longer actively used to a separate storage device for long-term retention.
Archive data consists of older data that is still important to the organization and may be needed for future reference, as well as data that must be retained for regulatory compliance.
Data archives are indexed and have search capabilities so files and parts of files can be easily located and retrieved.

4. Traditional Archiving
Today’s Archiving

5. Publications/Books Our example! Digital Library
All books published (1864 – 2000)
1,5 million pages
Each page = 1 tiff image
Possible rebuild all original publication (blank pages also)

6. Digital Library
Publications from 2000 are ine.pt, in PDF format.
Ongoing migration of all tiff files to pdf. Should be available in 2017.
New Digital library:
Will be 3250 volumes for infra-annual editions;
With treatment already: 2350 volumes
(so far for statistical publications and studies reviews)
Example – Monthly Statistical Bulletin will be available since 1929 until today without changing its name/title.

Why do we need archiving?

It is Nice to have it??

11. Web archiving is valid also to databases – native digital documents.
Some ideas for discussion!
Would we need to archive data if we only had publications in paper format?
An archiving policy applied for digital statistical data must be defined.
Web archiving is valid also to databases – native digital documents.
External services won’t arise trust issues? Loss of Statistical Confidentiality?

12. Traditional Archiving - Acessibility
Easy and physical accessible
High lifetime
Sensorial/historial experience

13. Today’s Archiving - Accessibility
Technology (software & Hardware) dependent
Easy copy and transport
High lifetime (???!!!!). Should we still read on the future?
How to read data from the past with new H&S?

15. Example for PDF files Some more questions, for discussion….
Do we need to move our data to new media all the time?
Should we have a standard for archiving?
Example for PDF files
PDF/A
PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents.
PDF/A differs from PDF by prohibiting features ill-suited to long-term archiving, such as font linking (as opposed to font embedding) and encryption.
