Hello.

In order to not hijack the ODB++ discussion, here's this other message.

Is IPC-2581 support feasible? They mention about being open. But I'm not
sure how open, because isn't an ISO/IEC/ECMA/IEEE standard and that worries
me.

It seems most IPC standards require certification and documentation is
sold, not free at all.

Here's an old "bug" about adding IPC-2581 support: https
<https://bugs.launchpad.net/kicad/+bug/594013>://
<https://bugs.launchpad.net/kicad/+bug/594013>bugs.launchpad.net

This is the related IPC-2581 open source stuff I found:
https://github.com/curtacircuitos/pcb-tools/commit/29deffcf77e963ae81aec9f8cbc61b029f3052d5
https://github.com/Cobra-Kao/ipc2581_to_odb

A Japanese guy said the following: " As a hobby, wrote my own IPC-2581
parser which covers all (161?) tags. Used Perl script to automatically
generate most part (about 7000 lines in C++) of parser code, from "formal"
format definition in xsd (2249 lines)."

Some subtle reference to IPC-2581

It's free to join the consortium, but it requires a corporate entity it
seems: http://www.ipc2581.com/index.php/join-the-consortia

There's Associate Membership too:

An user said the following about IPC-2581: "IPC-2581 is similar to the
Linux OS as it's an open source code with a consortium developing it.
Hopefully there will only be one flavor."

Use plugins. The ODB++/IPC-2581 ones could be kept outside mainline
Kicad if we would ensure they can be easily installed by a non-programmer.

- my 5 cents,
