ISO 24517-1:2008 is an ISO Standard published in 2008.
This standard defines a format (PDF/E) for the creation of documents used in geospatial, construction and manufacturing workflows[1] and is based on the PDF Reference version 1.6 from Adobe Systems. The specification also supports interactive media, including animation and 3D.
PDF/E is a subset of PDF, designed to be an open and neutral exchange format for engineering and technical documentation.[2] For PDF 2.0, PDF/E-1 is superseded by the PDF/A-4e conformance level.
