Adobe Systems is taking the first step toward having its entire PDF specification recognized as a global standard by the International Organization for Standardization (ISO).

The vendor announced Monday plans to submit the full PDF 1.7 specification to enterprise content management nonprofit organization the Association for Information and Image Management, with the hope that AIIM will then recommend ISO adopt it as an international standard.

In part, the move was driven by a growing proliferation of ISO standards around different subsets of the PDF specification, according to Sarah Rosenbaum, director of product management with Adobe. "It was becoming a bit of an alphabet soup dependent on industries or uses of the specification," she said.

PDF/Archive (PDF/A) and PDF/Exchange (PDF/X) are already approved ISO standards, with two more under consideration and likely to become standards in the next eight to 12 months: PDF for Engineering (PDF/E) and PDF for Universal Access (PDF/UA). Additionally, AIIM has proposed PDF for Healthcare (PDF/H) as a best practices guide.

Having PDF 1.7 as an ISO standard should make life easier for organizations that need to comply with government-mandated strategies to use the format. "The entire spec will be available as an umbrella standard," Rosenbaum said.

She doesn’t see Adobe’s decision as a response to the recent moves toward standardization recognition by the backers of dueling electronic document formats—the OpenDocument Format (ODF) supported by Sun Microsystems, IBM and open-source players like OpenOffice.org versus Microsoft’s Office Open XML (OOXML). In May 2006, ISO approved ODF as an international standard and is currently considering whether to give the same recognition to Open XML.

Adobe’s work to have PDF subsets approved as ISO standards dates back to 1995, when initial work on PDF/X began.

The process to gain ISO approval for PDF 1.7 will begin with the formation of a joint technical committee under the auspices of AIIM whose members will include Adobe, Microsoft and enterprise applications vendor SAP, Rosenbaum said. The group will flag any issues that need to be addressed in the specification and how to resolve those problems and produce a draft document that it will present to ISO for further development of PDF as an international standard. The entire process could take one to three years before PDF 1.7 becomes an ISO standard, and at any point in the proceedings, changes can be made to the specification, she added.

In the meantime, work won’t stop on the other ISO PDF subset standards currently in development, and Rosenbaum doesn’t expect any change in the use of PDF/A or PDF/X.
