Copying (partially) tag wiki from one site to another. Attribution and best practices?

Question

I found a great tag excerpt and tag wiki in one Stack Exchange community (say, Stack Overflow). In another community (say, Computational Science), we have the same tag with totally missing usage info. Now, I want to reuse most of the text from Stack Overflow tag wiki by a copy-paste with edits to drive the usage guidance to the rules and needs of Computational Science.

Since the tag excerpt does not allow any links and would be edited for the needs of the community, there is nothing that should be done.

For the tag wiki, it is possible and probably necessary to give the proper attribution according to the CC BY-SA 3.0 license requirements. I found one question on Meta regarding this topic which also mentions the required attribution. However, no example is given.

I am intended to do the following:

• copy/edit tag excerpt and tailor it

• copy tag wiki + edits and add the following in the end:

  The contents of this tag-wiki originates from "julia" tag-wiki description at Stack Overflow and was edited to reflect usage guidance and advice specific for the Computational Science community.

1. Does it seem like an appropriate attribution? I am a bit lost in whether I fulfill the 3.0 license attribution requirements in this particular situation.
2. Are there examples of such tag wikis with attributions anywhere within SE?
3. Am I worrying too much? :)

To be a bit more specific, no blind copy-pasting is intended. However, the fact that the tag wiki originated (was based on, used as a fundamental building block) from a tag wiki in another SE community, should be properly attributed.

1. Does it seem like an appropriate attribution? I am a bit lost in whether I fulfill the 3.0 license attribution requirements in this particular situation.

Yes, that's fine. I am not a lawyer, but if I interpret the rules correctly, you don't need to credit the author(s) (which is required in some cases) since they're not visible on the tag wiki page, and for some elaborate tag wikis you'd need to minutely investigate the edit history to see who actually wrote what. Otherwise, attribution rules on Stack Exchange are often not followed to the letter of the law but, as I personally see it, to the spirit of the law.

2. Are there examples of such tag wikis with attributions anywhere within SE?

Meta Stack Overflow is full of tag wikis copied (almost) verbatim from here (which isn't really surprising, since for a long time this site was Meta Stack Overflow). Here is an example.

Most of the times the content is just copied, without attribution and (equally bad) without tailoring the content to the new community. Examples are abound, e.g. most programming language tags on the technical Stack Exchange sites have been copied from Stack Overflow at a certain point in time and aren't updated. For example, one tag wiki lists Java 8 as the latest Java version :)

3. Am I worrying too much? :)

That's a matter of opinion, I guess. You've got the attribution covered, but I agree with @rene's comment; please check if the original tag wiki is properly attributed. If it's not, well, it's never too late to correct that mistake. Generally, I would say you can put your energy now into providing good content "to reflect usage guidance and advice specific for the Computational Science community."
