Abstract
The use of appropriate fonts and file formats for long-term maintenance of digital assets is a challenge for organizations in the public sector. The article reports from a study which investigated the PDF/A conformance and font usage in PDF files provided by Swedish public sector organizations (PSOs). This article presents an analysis of the PDF files' properties and font usage including a categorization of fonts' licenses. This study is motivated by the PDF/A-1 standard's requirement that ‘only fonts that are legally embeddable in a file for unlimited, universal rendering shall be used.' Analyzing PDF sets from three PSOs, the finding shows that the proportion of files that claim or succeed at conforming to PDF/A greatly varies among the sets despite similar backgrounds. Although the most popular way to make use of fonts is by embedding a subset of the font data, for some fonts expected to be ‘always available,' a considerable proportion of PDF files does not include any font data. This puts the onus of locating this data on the PDF reader which is problematic for long-term archival.
对于公共部门的组织来说,使用适当的字体和文件格式来长期维护数字资产是一个挑战。本文报告了一项研究,该研究调查了瑞典公共部门组织(pso)提供的PDF文件中的PDF/ a一致性和字体使用情况。本文分析了PDF文件的属性和字体使用情况,包括字体许可的分类。这项研究的动机是PDF/ a -1标准的要求,即“只能使用合法嵌入文件中的字体,以实现无限的、通用的渲染。”分析三个pso的PDF集,发现尽管背景相似,但声称或成功符合PDF/A的文件比例在集合之间差异很大。虽然最流行的使用字体的方法是嵌入字体数据的子集,但对于一些希望“永远可用”的字体,相当大比例的PDF文件不包含任何字体数据。这就把定位这些数据的责任放在了PDF阅读器上,这对于长期存档来说是有问题的。
