The DEXPI XML format

The DEXPI website at https://dexpi.org defines the objective of the DEXPI initiative to be "to develop and promote a general data exchange standard for the process industry", with a special focus in "the exchange of Piping and Instrumentation diagrams (P&IDs)". Accordingly, to enable this data exchange, the DEXPI initiative has defined an open XML format. Exchanging P&ID related data in the DEXPI format can be useful especially when different design disciplines use different software products, and the distribution and updating of data needs to be managed efficiently.

CADMATIC P&ID can import DEXPI XML files that have been exported from any software that supports DEXPI XML export, and CADMATIC P&ID can also export this format. Imported attribute data can be stored in COS in "External Data Management" (EDM) objects which are then linked to diagram objects, so that P&I designers can view the data.

Format

See the official DEXPI documentation.

Benefits

P&I diagrams created in other software programs can be imported into CADMATIC P&ID with document attributes, intelligent object attributes, pipeline division, and graphics.
P&I diagrams created in CADMATIC P&ID can be exported as DEXPI XML documents for import to other software programs. The export files contain all the data that the CADMATIC administrator has defined in the DEXPI mapping tool.
