Is there a standard ethical codex for publishing of research? I am asking about some kind of standard well known and complete ethical codex with versions of strictness (a list of rules comparable to the creative commons licenses in the field of software/art publishing).
It seems to me that every journal has its own ethical codex stated, although all of the codexes seem to be almost the same (with minor differences). It seems a little bit silly to me.
I would like to know about something usable like:

to tell my team: &quot;all publishing should be done according to the ethical codex XY v1.x&quot;, or
I would like to state in my hypothetical journal: &quot;the journal complies with the ethical codex XY v2.x&quot;

What am I missing? Where I can find it? Does some open ethical codex standard exist?  If not, why not?
The Committee on Publication Ethics (https://publicationethics.org/) &quot;is a nonprofit organization whose mission is to define best practice in the ethics of scholarly publishing and to assist editors, publishers, etc. to achieve this.&quot;
They have many documents; you can probably start with their core practices.  These cover:

Allegations of misconduct
Authorship and contributorship
Complaints and appeals
Conflicts of interest / Competing interests
Data and reproducibility
Ethical oversight
Intellectual property
Journal management
Peer review processes
Post-publication discussions and corrections

(Note that this focuses on publication ethics.  If you want research ethics then that would be a separate question.)
