The ISO 15926 is an interoperability standard in the process industry. ISO 15926 includes the Work In Progress (WIP) database. WIP is available online and includes technical class descriptions of all the main equipment items, pipe, instruments, buildings, activities and anything else used in engineering, constructing, procuring, operating and maintaining process facilities.
The ISO 15926 Reference Data Library contains the approved core library set and the Object Information Models (e.g. product models), but is expanded with proposed classes and proposed model extensions.
To expand the set a user must be certified. This is to keep the Reference Data Library in a certain structure, and directly usable for all the various connected projects.
When a new item is submitted by a certified user, it can be used immediately, and it will also enter an approval cycle performed by modeling and domain matter experts. In this cycle the new item can reach a higher status of approval; up until ISO certification.
In order to create the WIP, the builders needed to have the content, the infrastructure and the tools.
