The result of this work, and the first of the subsets, was PDF/X. A few years later a variety of government and business interests came together to produce PDF/A, the PDF subset focused on long-term archiving of PDF documents. It was the very public work on the development of PDF/A that led to other industries working to bring about the other standards listed here.
In 2007, Adobe recognized that it was time for the full PDF specification to be brought to the ISO. This led to the publication of ISO 32000-1, which turned PDF 1.7 into a fully open international standard.
