4. TIFF ("Tagged Image File Format“) és una estructura preestablerta i específica de
bits per a l’organització d’una imatges amb etiquetes.
Els fitxers TIFF contenen, a més de les dades de la imatge pròpiament dita,
"etiquetes" en les quals s'arxiva informació sobre les característiques de la imatge,
que serveix per al seu tractament posterior.

22. The METS schema is a standard for encoding descriptive, administrative, and structural
metadata regarding objects within a digital library, expressed using the XML schema language
of the World Wide Web Consortium. The standard is maintained in the Network Development
and MARC Standards Office of the Library of Congress, and is being developed as an initiative
of the Digital Library Federation.

33. Official standardization process started at the end of 2016
Recommendation of TIFF for Archives already submitted to the ISO TC-171
• Similar to PDF/A the TI/A initiative defines “tags” of TIFF as not recommended,
optional and required.
• The recommendation for TIFF in archival environments is precisely specified
based on feedback of the expert user community and a large (> 2 M files) survey
of „hot“ data.
• The aim of the recommendation is to prevent the need for early migration due to
wrong chosen features.
• The recommendation is focused on technical aspects and not on content based
archival concepts (e.g. compression).

37. “DPF Manager is very easy to
install and extremely easy to use”
“The tool is very fast –
80 TIFFs need less than a minute”
“I think in terms of usability
this tool has easily won the contest”
“HTML output is very nice and there is also METS and XML”
