pid-parser turns a P&ID drawing into SQL tables and a graph

A vision model finds the symbols and plain image processing finds the connections, then it exports CSV, SQL, GraphML and Cypher. The author tested it on one dense open dataset sheet, not on the workflows he lists.

For process and chemical engineers: once a drawing is a table, you can ask which valves sit between a pump and a tank, or what a valve isolates, then check the answer against the sheet.

pid-to-digital-twin builds a tagged Ignition and PI AF model from P&IDs

AI vision reads the symbols and tags, code traces the lines, and the output is scored against public answer keys. The repo says every extracted item is unverified until reviewed, and that no operations review has been done yet.

For controls and reliability teams: it targets the first step of a digital twin project, retyping tag lists by hand, and it ranks items by review risk so engineers know what to check first.
