UnionStation framework parses MODCA, IOCA, FOCA, PTOCA etc. into live objects and easily creates indices
Some legacy solutions are like state machines — they interpret input such as PostScript and AFP, execute the commands, and modify their internal states as it goes. Before long, the number of states and the interaction among them would go out of control and the system would become rigid and fragile. Modern solutions typically chose to use an object-oriented approach where the focus is centered on creating, sharing, and managing live objects who take care of states and actions by themselves.
AFP was designed as a mixture of control flow and embedded data, and the mindset of the designer was largely procedural. However, with UnionStation the task was tackled with the modern vision. The various “CA” (Content Architecture) specifications iterated the various types of data blocks, so it was upon us to create an integral and ordered blueprint of entities from the large collection of discrete parts.
The objects are further convertible into PDF or HTML or they can be exported to another AFP. Unlike most other solutions, there is no distinction between AFP reading module and AFP writing module — the same AFP module is able to read and write AFP data, converting properties to and from raw data, either generating new data from assigned properties on the fly, or taking existing binary data to ensure maximum fidelity and efficacy.
