Architecture continues to grow and adapt
by Harry Lewis
As you may have noticed, we’ve made some recent changes to our AFP Publications page. We have published an updated IPDS Reference (AFPC-0001-10) and introduced a brand new specification for metadata objects in AFP, MOCA Reference (AFPC-0013-01). These additions represent some exciting changes that are addressing feedback we’ve received and keeping up with new directions in modern document architecture.
The new Intelligent Printer Data Stream (IPDS) Reference includes 31 separate architecture changes ranging from editorial updates to adding support for several new functions defined across AFP, including full text objects, resident resources, group-level jam recovery, and new bar codes and graphics. The updated reference tracks the evolution of IPDS, one of the architecture’s greatest strengths, as AFP is adopted across a wider range of production printing industry segments and solutions.
Published for the first time, the new Metadata Object Content Architecture (MOCA) Reference defines a syntax for carrying metadata in AFP. This underlying metadata object is essential to the implementation of AFP/A (archive) and will allow improved accessibility for users with disabilities in the future. AFP/A is a sanctioned ISO project referred to as TC171 DIS18565.
The AFPC chooses to periodically share updated references with the public so the general AFP development community can make use of them. In the IPDS Reference developers are urged to pay close attention to changes and additions to command, order and triplet syntax. There are also 18 new exception IDs defined for error conditions detectable by an IPDS printer.
With these new references and AFP/A making its way through ISO Standard certification, it’s an exciting time to be involved with AFP. Keep an eye on this blog for more updates as they come.
