ODF (ISO/IEC
26300:2006. Information Technology—Open Document Format for Office Applications
[OpenDocument] v1.0) is an XML-based open file format. Regardless of ISO-announced standards,
some errors in these file formats have been reported. For example, although PDF/A-1 is for longterm
preservation of and access to documents, studies reveal that the feature-rich nature of PDF
can create difficulties in preserving PDF information over time.18 To overcome the barriers of PDF
and PDF/A-1, XML technology seems prevalent for digital resources in archiving systems and
digital preservation.19 The digital repository community is treating XML technology as a panacea
and converting most of their digital resources to XML.
