Why Do We Need ISO 15926?
The short answer is: "So we can exchange complex plant information with each other easily."
A slightly longer answer is: "To mitigate the current high costs of rekeying, and reformatting information to move it from one proprietary system to another."
For example, take the task of designing and sepcifying a process instrument for a plant modification. Imagine how many times information has to be rekeyed after the instrument is basically designed, until it is installed and commissioned in the target plant:
- After design, enter the information into From the design datastore, likely a datasheet in Excel, or a database.
- Each bidder will enter some of the data values into proprietary software to make a selection.
- After selection, each bidder modifies some data values and transmits it back to the engineer.
- Rekey certain data values from the winning bid into the engineer's premanent database.
- Data turnover to the client is likely something like an excel file for each datasheet.
- The owner will rekey certain data values into an asset management system.
The situation is improving. A few years ago the datasheets would have been printed and faxed to the vendors who would manually add what they had to and fax them back--now we email editable electronic files. And there are proposals to streamline the final handover so that it is already in the form required for the owner's Asset Management System--but the configuration costs speak to the complixity of the issue.
What we need is a way for each participant's software to be able to communicate complex information to each other without having to know in advance what needs to be communicated.
ISO 15926 is a Babel Fish
If you wanted to listen to Vogon poetry spoken in the original, you might use a Babel Fish.
The Babel Fish would listen to the Vogon speaking, then rearrange the syntax and translate all the words all on the fly, so to speak.
ISO 15926 acts like a Babel Fish by acting as an interpreter between two otherwise incompatible systems.
